        "description": "- Poppet construction for high dirt tolerance\n- 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\n- Can be mounted close to actuator, reducing length of pipe to be pressurized/exhausted on each cycle\n- Internal/external pilot supply\n- Near zero leakage",
