Automatic control valves include.

Automatic flow control valves.

2 and 2 a combination automatic flow control valve afcv isolation valve with threaded ends. Pressure reducing valves flow control valves back pressure sustaining valves altitude valves and relief valves. In april 2018 ocv control valves a family owned company was acquired by and began operating under the mat holding group umbrella. 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.

They can be directly operated i e. Automatic control valves as described by en 1074 5. Isolator r isolator y and k valves are available with a wide range of flows and psid. The umt comes standard with two pressure and temperature test plugs and additional ports for optional accessories.

Flow control valves are essential for optimising system performance and relying on a flow passage or port with a variable flow area. Save time and money with automatic flow limiting valves with griswold controls. The procedure to manually balance a system is very labor intensive. An altitude valve controls the level of a tank.

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. The range includes pneumatic and hydraulic control valves which are designed to cope with high flow rate working pressure and can be used for a variety of. 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. 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.

Parker flow control valves are designed to regulate the flow rate and pressure of media through a pipeline. For a demonstration of the flow control valve in action click here. The force is applied via a spring or diaphragm directly to the obturator. 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.

Automatic pressure independent valves are the cost effective option over manual balance valves. Automatic control valves do not require an external power source meaning that the fluid pressure is enough to open and close the valve.
