Available in double acting style (air to open and close) or spring return style (air to open, spring closes when air is exhausted). Valves include cast iron bodies, EPDM seats, 316 stainless discs and 416 stainless stems. Valves are rated to 250 PSI and 250 Deg. F. (See more details on valve this page). Air actuators are direct mount (no brackets) and include 1/4" FPT air port connections.

Designed to open/close valves at 100 PSI in most applications (120 PSI maximum air pressure for Matryx actuators; 150 PSI maximum for Keystone actuators).

NOTE: The EPDM seats used in these valves are not suitable for use with Diesel Fuel. Buna & Viton® available.
