The Multi Instruments 150 – 600# ANSI/ASME standard isovent gauge valve is a needle pattern valve with a non-rotating spindle tip, ensuring a positive bubble tight shut-off function.
The instrument is usually fitted directly on the manifold adapter which is mounted directly on the process nozzle.
This manifold is standard produced in AISI316 material, but “exotic” materials are also available.
Maximum working pressure is 420 Bar
Maximum temperature is 200°C
Vent and/or testports will always be 1/4″ threadsize, independent of process connection sizes.
For ordering information please consult the Model Code Wizard for port connection types available.
