Series 27 Poppet Valves for Line Mounting Series 27 Poppet valves for line mounting are available with single or double solenoid pilot control, or an air head for pressure control. Valve elements have end-guided stainless steel stems. Flush flexible manual override buttons are standard on solenoid models. Solenoid models listed in this catalog use an internal pilot supply. They are, however, easily field-convertible for use with an external pilot supply. Models for external pilot supply may also be ordered from ROSS. FEATURES: • Poppet construction for near zero leakage & high dirt...

Series 21 Poppet Valves for Line Mounting Series 21 High Temperature and Low Temperature Service Series 21 valves are configured like the Series 27 valves, but are designed with metal internals and special seals appropriate for use in more extreme temperatures. The valves are designated as either Type H (High Temperature) or Type O (Low Temperature) valves. Temperature specifications for the two types are given below. Solenoid models listed in this catalog use an internal pilot supply. They are, however, easily field-convertible for use with an external pilot supply. Models for external...

Anatomy of a Vacuum Service Valve Special ROSS poppets are the toughest available, ideal for dirty vacuum applications. ROSS poppets also have large flow areas, which allow high flow. Pilot can be fed to port X-1 externally by compressed air. Internally, atmospheric pressure can be used as pilot for “full vacuum” version. 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. Typical applications place vacuum or atmosphere on port...
