Description Yunyi stainless steel pneumatic one-way valve
The one-way valve is that the fluid can only flow along the water
inlet, but the medium at the water outlet cannot flow back,
commonly known as a one-way valve. One-way valve is also called
check valve or check valve. Used in hydraulic systems to prevent
reverse flow of oil flow, or used in pneumatic systems to prevent
reverse flow of compressed air. There are two types of check
valves: straight-through and right-angle. The straight-through
check valve is installed on the pipeline with a threaded
connection. Right-angle check valves are available in three forms:
threaded connection, plate connection and flange connection.
Features Yunyi stainless steel pneumatic one-way valve
1. One-piece valve body, compact structure;
2. Maximum working pressure: 207 bar (3000 psig);
3. Various end connections and body materials.
The thickened valve body can increase the pressure bearing height
under the same pressure bearing conditions, which is safer and more
secure.
No soldering required
It does not need welding when it is connected with the steel pipe,
which is beneficial to fire prevention, explosion-proof,
high-altitude operation, and can eliminate the disadvantages caused
by inadvertent welding.
Good performance and high quality
Forged by precision machining, polished and polished, smooth
without burrs, with high hardness, strong toughness, strong sealing
and other characteristics, corrosion resistance and corrosion
resistance.
The product connector is firmly connected
The ferrule joint has a firm connection, high pressure resistance,
good sealing and repeatability, and safe and reliable work.
