Pneumatic V-shaped adjustable control valves
features
ZYHV pneumatic v-type regulating control valves (hereinafter referred to as regulating control valve), is a kind of adjusting valves, and the execution unit of pneumatic unit combination instrument, generally combines with electric valves locator or pneumatic valves locator for usage. V-type regulating control valve spool opened a v-shaped incisions, and the seat relative rotation produce shearing force, prevent jammed. Especially suitable for mud and contain fiber medium, and contain tiny particles and contain suspended medium regulation. Shanghai Yihuan flow control equipment Co.,ltd produced pneumatic v-type regulating valve is widely used in petroleum, chemical, pharmaceutical, metallurgical, textile, paper, sewage treatment and production department gas, steam, liquid medium in pipelines flow control, in order to achieve production process control requirements. Pneumatic v-type regulating valves nominal pressure rating has PN1.6, 4.0, 6.4 MPa, nominal diameter scope from 25mm to 300mm, allowed leakage has Class IV and Class VI.
