This range of metal quick exhaust valves is offered in nickel-plated brass, aluminium and stainless steel.
These valves, which are suitable for any environment, increase the return speed of the cylinder rod by allowing the exhaust to pass directly to atmosphere.
Features/Benefits:
– Time Saving & Compact
• Reduction in cycle times: return speed improved
• Dimensions optimised for space reduction
• Exhaust silencer incorporated on some models
• Excellent exhaust capacity
• Robust
– Nickel-Plated Brass or Stainless Steel
• Ideal for applications in restrictive environments
• Orientation as required
• Many installation options and choice of silencer
• Designed without retention areas to optimise frequent cleaning operations (stainless steel)
– Aluminium
