Flow Control Valve/Jacket Valve
Introduction:
Flow control valves are the flow control system for special valve products manufactured by Yofull Company.
Onve Yofull vessel bottom control valve is used, there is no meed to be depolyed with any other kind of valves.
Yofull control valves can carry out no-dead-zone flow control to the high pressure system.
When using Yofull control valves, flow control by users are free of limitations of traditional valves.
Features:
- No limitation on the types of valves.
- One valve can be used both as a stop valve and control valve.
- Low pressure system control provides gas membrane actuator and pneumatic cylinder actuator.
- High pressure system control applies electrical actuator and hydraulic element.
