A valve that controls the flow of air that passes through the valve. Used often for retardation or timing circuits, but especially for regulating the piston speed in cylinders. ( 010)
A manually controlled valve generally located in the hot water supply line used to increase or decrease the flow of a liquid in a system.
A valve which controls the rate of flow of hydraulic fluid.
A valve that can be mechanically adjusted to restrict flow and thus discharge pressure.
A cylindrical pressure-compensating valve installed to regulate the flow of water. Rated in gpm or gpd.
Check valve that prevents a reverse flow of water when a hot water heating system is turned off.
A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners.
