CS - Quick Exhaust Two-way Valve
A high-performance quick exhaust valve for rapid actuator chamber venting in on/off applications.
Compact, high-flow design enables rapid actuator exhaust for improved system response
Robust construction with anodised aluminium or stainless steel 316 for durability in harsh conditions
Flange-mounted configuration ensures easy integration with actuators and SL exhaust protection systems
The CS Quick Exhaust valve is engineered for rapid venting of actuator chambers in critical on/off applications. Designed for both single and double-acting actuators, it ensures swift operation even when piloted by a small CV device. Its compact design allows flange mounting on actuator caps, making it highly adaptable to standard, offshore, and extreme environments, including sandstorm and copper-free conditions. Constructed with anodised aluminium or stainless steel 316, the CS valve operates efficiently across a wide temperature range. With a maximum exhaust CV of 60, it enhances actuator response time, ensuring optimal system performance in process automation.
