ZQEV Series

The Zeetork Quick Exhaust Valve (QEV) is a pneumatic device designed to rapidly expel air from a system, accelerating actuator movements like cylinders. It works by bypassing the slower exhaust path through the solenoid valve and directly venting air to the atmosphere. This enables faster actuator response, improved cycle times, and enhanced process control. QEVs are ideal for high-speed automation tasks, such as packaging and pick-and-place systems, or any application needing quick pneumatic actuation.

QEVs provide faster actuator response by reducing backpressure during exhaust, enhancing cycle time and production efficiency in automated systems. They enable the use of smaller, cost-effective solenoid valves without sacrificing speed. Acting as a secondary pressure relief, QEVs offer additional system protection. They also simplify retrofitting by easily integrating into existing setups. Their precise control makes them ideal for time-sensitive operations, improving automation reliability in industries like packaging and high-speed manufacturing.

The Quick Exhaust Valve (QEV) is installed directly on the actuator port or close to it, positioned between the actuator and the solenoid valve. This configuration allows rapid air expulsion during the actuator stroke, bypassing the slower solenoid exhaust path. Installation requires minimal modification and serves as a simple retrofit solution for existing pneumatic systems. Its compact size ensures easy integration, making it highly effective for upgrading production lines to achieve faster automation without major system redesign.

A Quick Exhaust Valve significantly improves actuator speed and process efficiency by allowing air to exit rapidly, preventing backpressure buildup. This leads to faster piston movement and shorter cycle times, which are crucial for high-speed operations such as packaging machines and pick-and-place systems. The QEV improves timing accuracy and system responsiveness in time-sensitive applications. Its ability to operate with smaller solenoid valves makes it a cost-effective solution for enhancing automation performance without needing large, expensive components.

Yes, the Zeetork QEV also provides secondary pressure relief protection by offering an additional exhaust path in case of over-pressurization. This prevents damage to actuators, valves, and piping caused by excessive pressure. The rapid exhaust mechanism reduces the risk of sudden jerks or uncontrolled actuator movement, contributing to safer operation. The valve’s simple integration enables safer retrofitting into existing systems, making it suitable for both safety-critical and high-speed industrial automation environments.
