Scanning For Ideas: The Incredibly Shrinking Check Valve
The High Pressure 156 Lee Chek valve from The Lee Co., Westbrook, Conn. (theleeco.com), weighs only 0.7 gm with a diameter of 0.156 in., but is said to be 2.5 times as efficient as high-pressure check valves of similar size.
The
all-stainless-steel
valve is rated for
5,000-psid work
pressure. Cracking
pressure can be 1
or 5 psid.
