Pneumatic angle seat valve manufacturer, factory and supplier for spring return normally closed and normally open. Pneumatic angle seat valve nornally closed is 304 316 2 way y type single acting pneumatically actuated piston valve for liquids, gases, steam and some aggressive fluids.Pneumatic angle seat valve nornally closed enables the plug to retract farther from the flow path, ensuring the highest flow capacity. The dual packing design, and a large diameter self aligning stem insures the highest cycle life. A full range of accessory items are available including limit switches, solenoid valves, manual override devices, stroke limiters.

Pneumatic angle seat valve nornally closed feature:
1.Visual position indication: can be connected to the limit switch or emergency manual device;

2. Easy to install: pneumatic head can rotate 360 degree. Easy to install one or two limit switches;

3. Pneumatic controller: thickened engineering plastic shell, low wear piston structure, large capacity and low gas consumption. Internal components self-lubricating, maintenance-free;

4. With a variety of control modes: normally open, normally closed, double action;

5. Smaller pneumatic actuator is required: when the fluid flows from above the pneumatic angle seat valve stem, smaller control head is optional;

6. Easy connection: MAMUR standard connection, embedded metal connector;

7. Long life guide rod: stem Teflon (PTEE) seal, avoid stolen goods import. Self lubricating, maintenance free. Pneumatic angle seat valve stem is specially treated to ensure that it is fixed and automatically positioned;

8. No water hammer effect, fluid from below the valve stem flow, water hammer (water impact) is absorbed;

9. Pneumatic angle seat valve nornally closed body mechanism: the flow is 30% larger than the ordinary Angle seat, the volume is smaller, the fluid flow is better. Stainless steel 304, 316 body, Teflon seal, life up to 7 million times.
