Frequently Asked Questions

What is an ARO quick exhaust valve used for?

An ARO quick exhaust valve, like the EV125, accelerates pneumatic cylinder retraction by venting exhaust air directly to atmosphere instead of routing it back through the control valve. This improves cycle speed in industrial automation, packaging, and material handling systems.

What are the specifications of the ARO EV125 quick exhaust valve?

The ARO EV125 quick exhaust valve has a maximum operating pressure of 125 psi and a minimum of 1 psi. It features 1/8 in NPT ports on both inlet and outlet. This compact valve is designed for reliable performance in pneumatic circuits requiring rapid cylinder movement.

Where to buy ARO quick exhaust valves worldwide?

3G Electric supplies the ARO EV125 quick exhaust valve to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial sourcing partner, we provide genuine ARO pneumatic components with technical support for your application.

How to install an ARO quick exhaust valve?

Install the ARO EV125 quick exhaust valve directly at the cylinder port using 1/8 in NPT fittings. Ensure the arrow on the valve body points toward the cylinder. Apply thread sealant to NPT threads and tighten to standard torque. Verify minimum 1 psi operating pressure for proper venting.
