Product Description

 

Product Description

Suitable for semiconductor, lithium battery and biopharmaceutical industry, inert bulk gas distribution, nitrogen for pneumatic application, process vacuum exhaust, dry, oil-free compressed air system, S-type solvent, such as isopropanol, respirable air.

Easy torque handle

Heavy duty long handle provides sufficient leverage to open or close the valve to prevent the flow of flowing fluid.

Full channel design

By using the same diameter of valve internal parts and connecting pipe, the fluid flow resistance can be significantly reduced. Eliminate butt weld and reduce contamination.

Ultra high pressure cleaning, packaging and testing

The final cleaning uses 18 mbdi water and high purity nitrogen from a low temperature source. Each valve is 100% nitrogen tested inside the seat and body seal

Pressure rating
Vacuum to 300 psi (20 bar
Test pressure: 150psi (10bar)

Leakage test: 1 × 10scc/sec
