PNEUMATIC QUICK EXHAUST VALVE SERIES – RQEV -900 (1/4”) / RQEV -910 (3/8”) / RQEV -920 (1/2”) / RQEV -930 (3/4”) / RQEV -940 (1”)
DESCRIPTION
The Rtork pneumatic Quick Exhaust Valve is a robust and efficient quick exhaust valve designed for rapid purging or exhausting of pneumatic systems. Constructed from durable SS316L stainless steel, it offers excellent corrosion resistance and reliable performance in demanding environments. With a 1/4″ NPT connection, the RQEV is easy to install and integrates seamlessly into various pneumatic applications. It operates within a pressure range of 0 to 12 bar and a temperature range of -20°C to +180°C. This valve is suitable for air quality meeting ISO Class 4 standards The RQEV ensures high flow rates (up to 11.0 Cv) for quick and effective exhaust, making it an ideal choice for optimizing pneumatic system performance.
FEATURES
Rtork Quick Exhaust Valve having simple, compact design and constructions that grants for reliability in operations Enables air to be exhausted quickly from air reservoirs and cylinders allowing higher cylinder speed to be achieved Specially designed for severe environments
Applications include marine environments, oil and gas production, chemicals and food processing, medical analysis, corrosive atmosphere etc.
Can be used in every position, but for a prompt fluid discharge it is suggested to connect them as near as possible to the cylinder
