Overview

ZZY type self operated pressure regulating valve does not require external energy. It uses the energy of the regulated medium as a power source, introduces an actuator to control the position of the valve core, changes the pressure difference and flow rate at both ends, and stabilizes the pressure before (or after) the valve. It has the advantages of sensitive action, good sealing, and small pressure set point fluctuations, and is widely used in automatic control of pressure reduction and stabilization or release and stabilization of gas, liquid, and steam media.

Product Overview

ZZYThe type of self operated pressure regulating valve does not require external energy. It uses the energy of the regulated medium as a power source, introduces an actuator to control the position of the valve core, changes the pressure difference and flow rate at both ends, and stabilizes the pressure before (or after) the valve. It has the advantages of sensitive action, good sealing, and small pressure set point fluctuations, and is widely used in automatic control of pressure reduction and stabilization or release and stabilization of gas, liquid, and steam media. This product has three types of structures: single seat (ZZYP), sleeve (ZZYM), and double seat (ZZYN). The actuator has two types: diaphragm type and piston type. The action types include pressure relief valve rear pressure regulation (B type) and pressure relief valve front pressure regulation (K type). The nominal pressure rating of the product includes PN16, 40, and 64; Valve body diameter range DN20~300; There are three levels of leakage levels: Level II, Level IV, and Level VI; The traffic characteristic is fast opening; The pressure is adjusted in stages from 15 to 250MPa. Can be combined as needed to meet user operating requirements.
