Internal thread stainless steel pneumatic angle seat valve

Features of Pneumatic Angle Seat Valve:
1. Visual position indication: limit switch or emergency manual device can be connected.
2. Easy to install: The pneumatic control head can be rotated 360°, and even the limit switch can be rotated 360°. One or two limit switches can be easily installed.
3. Advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low-wear piston structure, easy to large and low gas consumption. No internal parts are self-lubricating and maintenance-free.
4. It has a variety of control methods: normally open, normally closed, double action.
5. A smaller pneumatic actuator is required: when fluid flows from above the valve stem, a smaller control head can be selected.
6. Easy to connect: MAMUR standard connection, embedded metal connector.
7. Long-life guide rod: The valve stem is sealed with tapered Teflon (PTEE) to avoid the introduction of dirt. Self-lubricating and maintenance-free. The valve stem is specially treated to ensure the best fixation and can automatically correct its position.
8. No water hammer effect: When fluid flows in from below the valve stem, water hammer (water impact) is absorbed.
9. Advanced valve body mechanism: The flow rate is 30% larger than the ordinary angle seat, the volume is smaller, and the fluid flow pattern is better. Stainless steel 316 valve body, Teflon seal, high temperature resistance and corrosion resistance. Life span of up to 7 million times.

Possible failures of pneumatic angle seat valves and their troubleshooting methods:
The reason
Elimination method

Power on
Can't open

Power supply voltage is too low
Burnt coil
Medium pressure is too low

Adjust the voltage to within the range of use
Replace the coil
Increase pipeline pressure
Turn off the power
The valve does not close or closes poorly
Medium pressure is too high
Diaphragm is damaged or stuck with foreign objects
Deflection of the tower spring above the diaphragm
Reduce the pressure of pipeline media
Replace with a new diaphragm to remove foreign objects
Relocate the installation

Overview of Pneumatic Flanged Metal Hard Seal Butterfly Valve: D373H wafer type metal hard seal butterfly valve, also called flap valve, is a simple regulating valve, and it can also be used for on-off control of low-pressure pipeline media. Wafer metal hard seal butterfly valve is a kind of valve that uses a circular butterfly plate as an opening and closing part and rotates with the valve stem to open, close and adjust the fluid passage. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened.
