ЗЗЫ / ZZC / ZZV прямого действия регулирования давления иуп

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 2) Type: ZZY standard/ZZYP pilot/ZZC difference pressure/ZZV tiny pressureMain technical parameters: 1) Nominal size: DN 20-300mm2) Nominal pressure: ANSI 150-600lbs3) Flange standards: ANSI4) Leakage class: ANSI ≤VI5) Body's material: WCB/CF8/CF8M Characteristics: 1) Quick open 2) Temperature range: -20 +350°C shut off valve control valve micro pressure control valve
