Specify with confidence
Isolation duty, manual/actuated operation and access Connection, bore and preferred valve construction, including ball-valve requirements Coolant, wetted materials, working pressure and temperature Shut-off leakage criteria and required verification Quantity and assembly interfaces
Isolation valves provide a defined shut-off point for maintenance or equipment separation. The available access and connection arrangement matter as much as the valve body.
State manual or actuated operation, preferred construction, port geometry, coolant and pressure conditions. Specify seat leakage acceptance, actuation access and whether the valve belongs to a larger assembly.
Identify the line or assembly to isolate, the required connections and the space available for operation. Specify preferred construction, including any ball-valve requirement, without assuming suitability from valve type alone.
Provide coolant, material, pressure, temperature and shut-off leakage requirements, together with quantity and verification needs. Configuration and documentation are confirmed with quotation.
