Shuttle, Quick Exhaust, Flow Control

Check Valve

The body is made of anodized aluminum. A stainless steel valve, plated spring and Buna N Seal contribute to trouble free service.

Less than 1/2 psi pressure is required to open the valve. The valve is spring loaded and can be mounted in any position. Max. working pressure 250 psi.
Operating Temperature -40°F to +160°

Quick Exhaust Valves

The AVENTICS Quick Release Valves are pneumatic quick exhaust valves with NPT ports. A few psi pressure differential across the diaphragm opens the exhaust. Large internal air passages allow large volume flow. The diaphragm design eliminates chattering.
