Safety Valve: ?

Safety valves are overpressure protection devices for protecting personnel and equipment, and usually installed in HP operation line for cementing/fracturing pumps, pressure vessels and other equipment under HP and high displacement. The preset pressure value ranging 5000psi to 15000psi(35MPa to 105MPa) is adjusted through the top nut. When pumping pressure or operating pressure exceed the preset value, the safety valves will automatically open for pressure release. While the pressure is less than the preset value, they will be automatically closed.

Gate Valve:  

Gate valves are mainly used for control of fluid flow in drilling well control system and drilling fluid manifolds (such as, kill manifolds, choke manifolds, mud manifolds and standpipe manifolds).There are two types of valves: visible and invisible bar type. They can be manually or hydraulically operated.

1.Low opening torque is needed while under pressure;

2.End connections are flange, thread or union , and meet the requirements of API;

3.Valve plates and seats have high hardness and good wear-resistance performance;

4.Valve is an integral forging with high strength, load-bearing capacity and long service life, and suitable for sour environments including offshore drilling operations.

 PLATE GATE VALVE AND WEDGE GATE VALVE:

 The designs are conformed to the latest SY/T5127-2002,metal to metal seal is used between the body and the bonnet,metal seal or non-metal seal is used between the seat and the gate plate as needs. Back seal is set between the stem and the bonnet in order to replace the fill of the valve-stem when the valve bears pressure.The seal surface is welded with hard alloy of corrosion resistance and impact resistance.

For the parallel gate and the seat with preloaded spring ,operation torque is little.

The wedge valve gate is sealed by wedge seal surface ,it can adjust fit compactness between the seal surfaces by loading with a handwheel.

Plug Valve: ?

Plug valves, forged of quality high strength alloy steel, are low torque valves based on the technologies introduced from SPM. 1″,2″and 3″ plug valves with rated working pressure of 6000,10000,15000 psi(42,70,105MPa) are available. They can work in normal temperature, low temperature or H2S environments.

1.End connections of plug valves with sizes in English system may be union or male/female thread (LP,TBG), and they can be freely connected with products in international market;

2.Maintenance and repair of valve body can be done without removal, and no special tools are needed for removal;

3.The plugs have very good sealing performance?

4.Visible: There is a visible positioner where we can see if valve is open or closed. Brake spring will limit the position of valve;

5.3″hand wheel opener is suitable for opening in low temperature. Valves can be opened freely and flexibly.

Sure Flow Retainerless body design

In standard or competitive designs, some manufacturers drill four holes through the body of the check valve to facilitate the installation of a hinge pin and stop pin. The valves are then sealed by four pipe plugs. These holes are potential leak paths from the body of the valve.

Sure Flow Equipment Inc. utilizes an internal stop pin and hinge pin which are machined into the cavity of the body wall. This design eliminates a potential shell or body leak path.

Lapped body / disc seal

All valves meet or exceed API 598. When it comes to the Sure Flow metal to metal valve, an additional special machining cure is performed to provide a maximum flatness and a fine, lapped finish. The Sure Flow disc provides an almost zero leakage on metal seated valves with no additional cost.

Shock bumpers

Sure Flow Equipment Inc. has cast “Shock Bumpers” into the reverse side of each of the discs (flappers). Both sides of the disc meet or touch in the fully open position, thus preventing them from contact with the internal pins. This reduces the force on the hinges to a minimum.

In some competitive designs the disc (flapper) strikes the stop pin in the fullly open position, creating a lever force which could cause the hinge pin to break. The Shock Bumpers eliminate this potential problem.

Seat life

Increased seat life is obtained by eliminating the problem of dragging on the seat when opening. The soft seated valve has a seat molded to the body by use of a heating temperature suitable to the materials.

basin faucet

 Wether authentic, contemporary or cosmopolitan, it is not only the design of your faucet that will influence the look of your bathroom. The choice of mounting options and typologies plays a key role in terms of functionality and looks. 

Lineare single-lever mixer

Single-lever mixer faucets

Also referred to as monobloc faucets, single-lever mixers are designed for installation in a single hole in the basin surround. They feature a lever handle mounted on the top or the side of the faucet to control both the water temperature and flow. The hot and cold water is then mixed in an internal cartridge before it reaches the spout. Choose a faucet with ceramic discs and a wide operating angle, for smooth and precise control.

Atrio Ypsilon two-handle mixer

Two-handle mixer faucets

Like single-lever mixers, two-handle faucets are installed in a single hole in the basin rim. They feature independent controls for the hot and cold water supplies.

Atrio Jota three-hole mixer

Three-hole faucets

Featuring individual controls for the hot and cold water, three-hole faucets deliver the mixed water via a central spout. Available in a variety of designs, this style works well in both contemporary and traditional settings.

Europlus E electronic faucet

Electronic faucets

Two types of electronic faucet are available. Sensory-controlled (touchless) faucets sense the presence of the user, e.g. by using infrared light. One-touch faucets require the user to touch-start the water.

Atrio Ypsilon pillar faucet

Pillar faucets

Due to their authentic look, pillar faucets are often chosen for traditional settings. They deliver the hot and cold water supplies independent of one another.

Allure two-hole mixer faucet, wall-mounted

Wall-mounted faucets

For vessel style basins, or when there are no faucet holes in the sanitaryware, choose a wall-mounted faucet. As they are installed in the wall directly above the basin, the pipe work must be concealed in the wall prior to tiling.

product news

A ball valve is an extremely durable stop valve that is designed primarily for On/Off function. They provide tight shut-off and high capacity with just a quarter turn to operate. The position of the handle immediately indicates whether the valve is open or closed. In the open position there is virtually no obstruction to flow, and head loss through full bore ball valves is almost negligible. Along with being easy to monitor, ball valves have an advantage in that the seat performs a self-wiping action, preventing build up of foreign particles within the valve.

The body of ball valves may be manufactured from a wide variety of materials, including Brass, Stainless Steel, PVC, or many others

There are three general types of ball valves: full port, standard port and reduced port.

In a full port ball valve the hole in the ball is the same size as the hole in the pipe, flow is unrestricted and there would be minimal friction loss.

A standard port ball valve is generally less expensive, but has a smaller ball and hence a smaller bore. Flow through this valve is one pipe size smaller than the valves pipe size resulting in slightly greater friction loss than a full port ball valve.

In a reduced port ball valve, the bore through the valve is generally two pipe sizes smaller than the valves pipe size, once again this results in greater friction loss than a standard port ball valve.

Ball valves are extremely versatile and can handle many different types of liquids and pressures. It is important to consult the manufacturer’s technical data sheets prior to installation, this ensures the correct valve is being installed for the application. New valve designs, have also meant some types of ball valves may now be used in “High-Vacuum” applications. Some ball valves may also be fitted with Pneumatic actuators.

Advantage of Cast Iron Pipe Fittings:
Cast iron pipe fittings have several advantages over other types of fittings. Some of the notable advantages are:

• Performance: The performance and durability of cast iron pipe fittings are far better than other materials used for sanitary and storm drain, waste, and vent piping. Cast iron pipe fittings are extremely durable, nearly indestructible and does not react with most chemicals, and will not burn or melt except under the most extreme conditions. This decreases the hazard of poisonous gases in case of fire or other accidents. Cast iron fittings are also known for their unparalleled performance. These fittings are usually not preferred for pipes delivering water.
• Soundproofing Qualities: In most installations, neoprene gaskets and hubless coupling are used with cast iron pipe fittings. This in turn, minimises noise and vibration caused by the contact between pipe and pipe fittings to a great extent. The structure and composition of cast iron helps to dampen the sound rather than transmitting or amplifying it.
• Versatility: Cast iron pipe fittings are known for their versatility as they come with a wide range of joining methods that allow efficient installation both above and below the floor and even underground. Because of this feature, cast iron is mostly preferred for sanitary and storm drain, waste, and vent piping material on the market. They are also suitable for use in all types of building construction.
• Low Cost Installation: One of the significant advantages of cast iron fittings is that they ensure low-cost installation.

Investment casting is an industrial process based on and also called lost-wax casting, one of the oldest known metal-forming techniques. From 5,000 years ago, when beeswax formed the pattern, to today’s high-technology waxes, refractory materials and specialist alloys, the castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. Lost foam casting is a modern form of investment casting that eliminates certain steps in the process.

The process is generally used for small castings, but has produced complete aircraft door frames,
steel castings of up to 300 kg and aluminium castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.
