Allan Test-Block Valve and Integral Union Test-Block Valve
Positive-stop handle identifies selected operation and indicates direction of flow
Connections on center line easily installed -- no pipe stress
No cavities to collect contaminants -- self draining
Easy installation/removal
Stainless steel packing nut stops inter-port and steam leakage
High temperature design to 600 psi - 500ºF (41.0bar - 260ºC)
Allan valve offers Series STM Stainless Steel 3-Way Valves with or without integral spiral gasket union. Valve is available with integral union on inlet only or on both inlet and outlet.
Union connections on Series STM Valves provide fewer screwed connections, less installation labor and reduced down time. Series STM comes complete with adjustable position test pigtail. Series STM is standard with oval arrow handle, positive top-position indicator and 316 stainless steel internal parts.
Test steam traps accurately by the visual method using Series STM Valves. Series STM is a problem solving sampling system valve providing continuous flow sampling and eliminating multiple valves and fittings.
