Vacuum, Low/High Temperatures [Classic 21 Series] 2173B6901W
![](https://ross-admin-global-us-east.s3.amazonaws.com/production/uploads/series/image/927/21_Series_SlC_3-2_md.png)
- 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
