Pressure Reducing Valve Series

Product image
(Pressure Reducing Valve)

Stable Gas Supply, Safe & Efficient

The pressure reducing valve lowers the high gas pressure from a cylinder or pipeline to a stable low outlet pressure - a key component for gas appliances and outdoor cylinders. Internal channels are designed based on fluid mechanics for both high flow and stable pressure, ensuring stable and complete combustion.

Q: What does a gas pressure reducing valve do?

It reduces high gas pressure to a stable low outlet pressure, ensuring stable supply to burning appliances - a key safety component for gas appliances and outdoor cylinders.

Plug Valve Series

Quick Open/Close, Reliable Sealing

Plug valves connect or shut off gas pipelines by rotating the tapered plug. With a simple structure, flexible operation and quick open/close, they are widely used in gas pipeline control with a long service life.

Q: What is the difference between a plug valve and a ball valve?

A plug valve uses a rotating tapered plug for open/close - simple and quick to operate. A ball valve uses a rotating ball with lower flow resistance. Both can be used for gas pipelines; choose according to your application and pressure requirements.

Thermocouple & Safety Valve Series

(Thermocouple & Safety Valve)

Flame Failure Protection for Safety

The thermocouple flame failure device works with the safety valve: while the flame burns normally, the thermocouple generates electromotive force that keeps the solenoid valve open; if the flame goes out accidentally, the electromotive force disappears and the valve automatically cuts off the gas supply, preventing gas leakage at the source.

Q: How does thermocouple flame failure protection work?

When heated by the flame, the thermocouple generates electromotive force keeping the solenoid valve open. If the flame goes out, the thermocouple cools, the electromotive force disappears and the solenoid valve automatically cuts off the gas supply.

Medium Pressure Gas Valve Series

Q: What is the difference between medium pressure and low pressure gas valves?

Medium pressure gas valves are used in medium pressure gas supply systems with higher pressure ratings; low pressure valves are mainly for end-use appliance gas control. Selection depends on the system supply pressure.
