Spirax Sarco PF61G-2N0 Actuated Valve

The Spirax Sarco PF61G-2N0 Actuated Valve is a two-port, pneumatically actuated stainless-steel valve designed for on/off isolation in steam, water, air, oil and gases. It is part of Spirax Sarco’s PF6 piston-actuated valve family and uses a robust stainless-steel body with screwed BSP or NPT connections for straightforward installation in a wide range of piping systems. Available sizes span DN15 ½" to DN50 2" (examples include ½", ¾", 1", 1¼", 1½" and 2"), allowing you to match the valve to your line size. For automated control, the PF61G can be pilot-operated with a DM-type solenoid valve to enable reliable electro-pneumatic actuation in control loops. Variants cover NC (Normally Closed), NO (Normally Open) and BD (Bi-directional) configurations, with PF61G-2NC cited as a representative PF61G option; the 2 in the code denotes two-port construction. This valve is suitable for use in steam applications as well as water, air, oil and gases, providing quick, positive shut-off with a compact footprint suitable for process and utility isolation where reliable pneumatically driven control is required.
