R610/R640/R650 Series China Self-operated Control Valve

A self-operated control valve, also known as a self operated pressure control valveor self operated temperature control valve, is an auto control valve that relies on the pressure and temperature of the medium flowing through the valve as an energy source to drive the self operated control valveto work automatically and does not require an external power supply and secondary instrumentation.

Self Actuated Pressure Control ValveWorking Principle

A self actuated temperature control valveis a type of control valvethat regulates the pressure of a fluid in a system without the need for an external power source or control signal. It operates on the principle of pressure balance.

The valve has a diaphragm or a piston that separates the process fluid from a reference pressure fluid. The reference pressure fluid is typically supplied from a source that is independent of the process fluid, such as a compressed gas or a spring-loaded pressure vessel.

When the process fluid pressure rises above the set-point of the valve, the diaphragm or piston is pushed upward, which in turn restricts the flow of process fluid through the valve. This causes the process fluid pressure to decrease until it reaches the set-point of the valve. At this point, the diaphragm or piston moves back down, allowing the process fluid to flow through the valve again.

The set-point of the valve is typically adjustable and can be changed by adjusting the tension of the spring or the pressure of the reference fluid.

Self-actuated pressure control valves are commonly used in different kinds of application of control valve in industry to maintain a constant pressure in a process line or to protect equipment from overpressure. They are simple, reliable, and require minimal maintenance.
