Vacuum, Low/High Temperatures [Classic 21 Series] 2173B7901W
- 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
