A
Threaded in-line flow control valves are unidirectional flow control valves. Intake air flows freely through the flow control; exhaust
air is metered out through a specially designed adjustment screw. An arrow on the body of the valve indicates the direction of
controlled flow. The valves may be installed as meter in or meter out devices.
Technical specifications:
• working fluid: compressed air
• working pressure: 15 PSI to 145 PSI
• working temperature: 30°F to 160°F
Materials:
• body: nylon with nickel plated brass thread
• adjustment screw: nickel-plated brass
• locking nut: nickel-plated brass
• threads: nickel-plated brass
Legris Non-Return In-Line Check Valves
Allows air to pass in one direction while blocking flow in the other direction. A pressure of more than 7 PSI will overcome
the spring pressure and allow flow. An arrow indicates free flow direction. Maximum working pressure: 145 PSI at ambient
temperature (70°F)
Legris In-Line Check Valves
These in-line check valves allow air to pass in one direction while blocking flow in the other direction. Their extreme
compactness and light weight make them suitable as a safety item in compressed air circuits. The body of the fitting contains
an arrow to indicate the direction of flow. A pressure of more than 7 PSI will overcome the spring pressure, which is keeping the
valve closed, thus allowing the passage of air. Meter out check valve.
Technical specifications:
• working pressure: 15 PSI to 145 PSI at ambient
temperature (70°F)
Materials:
• body: nylon with nickel plated brass base
• pre-applied thread sealant on tapered threads
Stainless Steel Legris Uni-Directional Check Valves
Stainless steel valve blocks the fluid passage when the pressure differential is lower than 3.6 PSI.
Technical specifications:
• working pressure: 7 PSI to 580 PSI
• working temperature: -4°F to 360°F
Materials:
• body: 316L stainless steel
• shut-off valve: 316L stainless steel
• return spring: 302 stainless steel
• seals: Viton®
