A self-operated pressure control valve is a type of valve used to regulate pressure within fluid systems. It operates without the need for external power sources such as electricity or pneumatic energy. These valves utilize changes in fluid pressure to adjust their opening or closing, thereby maintaining pressure within the system stable within a specified range. This design is particularly useful in applications where preventing excessive or insufficient pressure is critical.

Regulating valves

The control valve is a crucial valve in the process of industrial automation. It’s mainly used for precisely controlling the parameters such as the flow rate, pressure, and temperature of fluids (like liquids, gases, or vapors).The control valve usually consists of an actuator and a valve body. The actuator drives the movement of the valve core in the valve body according to the control signal and changes the cross – sectional area of the fluid passage, thus realizing the adjustment of fluid parameters. It features high precision and good stability. It’s widely used in numerous industries such as chemical, petroleum, and electric power, capable of meeting complex process requirements and effectively improving production efficiency, product quality, and the safety and economy of system operation.

Self-acting Control Valve

The self – operated regulating valve is a valve that doesn’t require external energy and relies on its own regulating mechanism to control fluid parameters. It mainly consists of a valve body, an actuator and a regulating element.Its working principle is based on the energy of the medium itself, such as pressure and temperature changes, to drive the valve to act. When the regulated parameter changes, the regulating element will automatically adjust the valve opening so that the fluid parameter is stabilized near the set value. The self – operated regulating valve has the advantages of simple structure, convenient installation and energy – saving. It’s widely used in fields such as petroleum, chemical industry, heat – supply and HVAC. It’s especially suitable for systems that don’t require extremely high control accuracy but need stable operation, providing a reliable solution for the automatic regulation of fluid systems.
