Automatic flow control valves.

An actuator will stroke the valve depending on its input and set up allowing the valve to be positioned accurately and allowing control over a variety of requirements. An altitude valve controls the level of a tank. Have the integral capability to control the function using energy from the conveyed water by adjusting the position of the obturator. Isolator r isolator y and k valves are available with a wide range of flows and psid.

More complex control systems using valves requiring automatic control based on an external input i e regulating flow through a pipe to a changing set point require an actuator. Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area. They can be directly operated i e. Pressure reducing valves flow control valves back pressure sustaining valves altitude valves and relief valves.

For a demonstration of the flow control valve in action click here. Parker flow control valves are designed to regulate the flow rate and pressure of media through a pipeline. Save time and money with automatic flow limiting valves with griswold controls. An automatic flow control valve afcv with threaded ends.

Automatic control valves do not require an external power source meaning that the fluid pressure is enough to open and close the valve. Automatic flow limiting valves do not require any additional balancing as do manual balancing valves therefore they reduce labor costs from not having to balance and rebalance the valves. The procedure to manually balance a system is very labor intensive. Mat holding is constantly.

For more than 65 years ocv control valves has been a worldwide industry leader in designing and manufacturing hydraulically operated diaphragm actuated automatic control valves. A typical application for this type of automatic control valve is as a pressure type filter effluent control valve where a constant flow rate is maintained despite variation in head loss through the filter or anywhere a constant rate of flow is desired. In april 2018 ocv control valves a family owned company was acquired by and began operating under the mat holding group umbrella. The force is applied via a spring or diaphragm directly to the obturator.

The umt comes standard with two pressure and temperature test plugs and additional ports for optional accessories. Automatic control valves include.
