Page of TI-P7- CH Issue Cert. No. LRQ 9 ISO 9 PF Stainless Steel Piston Actuated On/ Off Valves Description A -port pneumatically actuated on / off stainless steel valve for use on steam, water, air, oil and gases. A pneumatic signal acts on the actuator piston to open or close the valve with a spring return action. A valve position indicator is included on standard and flow regulator models. Standard versions have PTFE stem seals for operation up to C. Optionally, high temperature stem seals (H) can be provided for operation up to 9 C. Valves are available with one of three sizes of actuator: Type (5 mm), Type ( mm) and Type (9 mm) with the following action options: - NC (Normally Closed) - Designed for flow over the seat (port to ). Caution: Not recommended for waterhammer prevention. - NO (Normally Open) - Designed for flow under the seat (port to ). Can be used to prevent waterhammer on valve closure in liquid applications. - BD (Bi-Directional normally closed) - Designed for special applications that require flow in both directions and incorporates an anti-waterhammer design for liquid applications flowing under the seat (port to ). Note: To help prevent the possibility of waterhammer on liquid applications flowing over the seat (port to ) the pressure should not exceed bar g. Optional extras (see 'Valve selection guide', page 7): - Travel switch. - Flow regulator.
