- Working Principle
In the non-working status, the valve is normally closed (open) due to spring force ,when actuator piston is compressed by air. The double-acting valve control by compressed air.
- Features
1. High flow rate,low fluid resistance, Y-type design increases 30% flow rate.
2. Position indicator: The limit switch and emergency manual are adaptable.
3. Easy installation: Actuator 360°rotated free.
4. Automatically position correction, Self-lubricating PTFE seal, maintenance-free, good stability.
5. Multi actuators to adapt different working status, normal, high temperature, heavy corrosion, etc.
6. Easy installation.7. Start frequently for a short time, high sensitivity. Precise temperature control, drip with liquid.
