ZZYP self-operated pressure regulating valve

Self-operated pressure regulating valve
No external energy is required, and the energy of the regulated medium is used as the power source to introduce the actuator to control the position of the valve core, change the pressure difference and flow rate at both ends, and stabilize the pressure in front of the valve (or behind the valve). . It has the advantages of sensitive action, good sealing, and small pressure set point fluctuation. It is widely used in the automatic control of pressure reduction and pressure stabilization or pressure relief and pressure stabilization of gas, liquid and steam media. This series of products has three structures: single-seat, sleeve, and double-seat (). The actuator has two action types: diaphragm type and piston type. There are post-valve pressure adjustment (type) for pressure reduction and front-valve pressure adjustment (type) for pressure relief. ). The nominal pressure grade of the product is ,, the valve body diameter range is D~, and the leakage level is grade Ⅳ, grade Ⅳ and grade Ⅳ. The three-speed flow characteristics are step-by-step adjustment of quick opening pressure. Can be combined as needed to meet user working conditions.

Features
The self-operated pressure regulating valve does not require external energy and can work in places without electricity or gas. It is convenient and saves energy.
The pressure segmentation range is thin and the cross-adjustment accuracy is high.
The pressure setpoint can be set continuously during operation.
To adjust the pressure behind the valve, the ratio of the pressure in front of the valve to the pressure behind the valve is:~:.
The rubber diaphragm detection actuator has high detection accuracy and sensitive action.
The pressure balance mechanism is used to make the regulating valve responsive and control precise.
