ZZY/ZZC/ZZV self-operated pressure regulating valve: 1) It is performer products achieving the self-regulation through the self-force of the controlled medium and saving energy at the same time. The setting value of the pressure and temperature may be regulated freely in the process of operation
Which has the feature of quick opening flow. With a number of advantages such
As the highly sensitive motion, stable controlled parameter, high-precision regulation, and small leak volume, the products are extensively applied to the automatic control for the pressure and temperature under various working conditions
