21 Vacuum Series

2171A4917Z

 

 

  • Poppet construction for high dirt tolerance
  • ROSS vacuum valves have larger orifices, allowing greater flow and easing the transport of air even though there is a small differential between the vacuum within the valve and atmospheric pressure outside the valve
  • Can be mounted close to actuator, reducing length of pipe to be pressurized/exhausted on each cycle
  • Internal/external pilot supply
  • Near zero leakage
