Forged throttle stop and vent valve-Gas valve series-燃气阀厂家-上海冠环阀门制造有限公司

Product Overview
Throttling, shut-off, and venting valves are widely used as closed circuit devices on pipelines for oil, natural gas, gas, liquefied petroleum gas, refining, airports, chemicals, and oil and gas storage and transportation.

Product Features
1. This valve adopts cage shaped labyrinth throttling, with a multi-level throttling effect.
2. The valve adopts dual sealing (hard and soft sealing) to ensure reliable sealing.
3. The sealing surface of the valve seat is sealed with a taper.
4. The valve disc is equipped with a balance hole and a piston type seal.
5. The throttle stop vent valve and double acting throttle valve have both throttling and shut-off functions (sealed to zero leakage).
6. The double acting throttle globe valve also has a multi-stage throttle function, with a large throttle pressure difference, and can be suitable for throttling and shut-off under high pressure.
7. The packing adopts a V-shaped packing structure with self sealing ability.
8. This valve can be repaired online, and the pipeline can replace a series of vulnerable parts such as packing under pressure.
