instructions

ZSHVE/ZDRVE series cut-off ball valve is a rotary cut-off ball valve, which is an execution unit in pneumatic or electric unit combination instruments, generally used in combination with solenoid valves and other components. There are two types of sealing forms: soft sealing and hard sealing, which are used under working conditions of -40 ℃~180 ℃ and -60 ℃~450 ℃, respectively. This series of products has the characteristics of high transmission efficiency, high thrust, good sealing performance, high rated flow coefficient, and good interchangeability of parts. This series of products is widely used for cutting off or opening media in gas and liquid pipelines in production departments such as petroleum, chemical, pharmaceutical, metallurgical, textile, papermaking, and sewage treatment, meeting the requirements of working conditions.

The "O" type cut-off ball valve adopts a cylinder piston pneumatic actuator or DCL electric actuator. The ball surface of the "O" type cut-off ball valve is hardened by a special process to make its surface smooth and wear-resistant. The valve seat and sealing material are made of high temperature resistant and wear-resistant carbon fiber material, and the product structure is exquisite and reasonable. This series of cut-off ball valves has two types: pneumatic piston "O" type cut-off ball valve and electric "O" type cut-off ball valve; The nominal pressure rating of this series of products is PN (mm) 1.6, 4.0, 6.4; Valve body nominal diameter range DN (mm) 15~300; The leakage standards include Level IV and Level VI; The valve core angle is 90 degrees, and various varieties and specifications are available for selection.
