Self operated pressure reducing valve with commander-Fornitore globale

Working principle and purpose of the product:

ZZVYP Type Self operated Pressure Reducing Valve with CommanderIt is an energy-saving pressure regulating valve that does not require external energy and relies solely on the pressure changes of the regulated medium to achieve automatic regulation and stabilize the pressure at a constant value after the valve.

This product can be used in high-temperature (200 ℃) steam environments without the need for a condenser.

Product Structure Features:

The pressure setting of the self operated pressure reducing valve with a commander is achieved on the commander, making it convenient, fast, time-saving, and labor-saving for continuous setting in operation; High control accuracy, comparable to the general ZZY type direct operated self operated pressure regulating valve, suitable for occasions with high control accuracy requirements; The detection and execution components are made of high-temperature resistant materials.
