Scanning For Ideas: The Incredibly Shrinking Check Valve

The High Pressure 156 Lee Chek valve from The Lee Co., Westbrook, Conn. (, 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.
