Plug Ball Cock Valve VS. Mini Ball Valve [2012-02-01]

 

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow in one direction, but is pushed open by flow in the opposite direction.
Function:Ball valves and plug Ball Cock valves perform the same function. Each kind controls the flow of liquids and gases either in a simple on/off function or as a multipath function.
Type:Ball valves and plug Ball Cock valves are generally called "quarter turn" valves because they need their handle turned only 90 degrees to change on/off positions. This does not hold true for three- and four-way valves.
Porting:Mini Ball Valve can be full port or reduced port. Full port means the ball is oversized and allows for full flow; reduced port means the ball is roughly the same size as the inner diameter of the valve and restricts flow. Plug Ball Cock valves are mostly full port.
Longevity:Ball valves tend to function reliably for years, even with long-term disuse. Some plug Ball Cock valves can eventually stick, becoming difficult to operate.
Control Capability:Ball valves do not offer the fine control of other valves for throttling purposes, but they can be used for some degree of throttling. In general, plug Ball Cock valves offer even less control for throttling.
