Automatic Control Valve Products
A flow control valve regulates the flow or pressure of a fluid. Flow 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. Pneumatically-actuated globe valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Control valves can also work with hydraulic actuators (also known as hydraulic pilots). These types of valves are also known as Automatic Control Valves. The hydraulic actuators will respond to changes of pressure or flow and will open/close the valve. Hydraulic Operated Automatic Control Valves do not require an external power source, meaning that the fluid pressure is enough for opening and closing the valve.
Automatic Flow Control Valves
Control valves regulate the flow or pressure of a fluid. They normally respond to signals generated by independent devices such as flow meters or temperature gauges. They regulate the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. They 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.
Pressure Control
Water Control valves can also work with hydraulic actuators (also known as hydraulic pilots). The hydraulic actuators will respond to changes of pressure or water flow and will open/close the valve. Flomatic also carries actuated solenoid valves.
