Product overview
Zzvp self operated micro pressure regulating valve this series of products are divided into single seat (zzvp, zzcp) and double seat (zzvn, zzcn) structures according to the valve core form of micro pressure regulating valve; The function types of micro pressure regulating valve include pressure regulation behind the pressure reducing valve (type b) and pressure regulation in front of the pressure relief valve (type K). Nominal pressure grades of products include pn0.1, 1.0 and 1.6 (MPA); Diameter range: DN20 ~ 300; The leakage level includes level II, level IV, level V and level VI; The flow characteristic is fast opening; The pressure regulation range is 0.4 ~ 150kPa, and the micro pressure regulating valve can be combined according to the needs of users to meet the working conditions.
