Product
PTM 1
Vent valve on top, isolation valve on the side, with the drain / vent port available at 1/4" or 1/2" NPT.
Manifolds
PTM 1
Two valve manifold is designed in a single block with female screwed inlet and outlet port combining isolation valve and vent / calibration valve. Generally used on static pressure transmitters, switches or gauges.
PTM 1 carries the vent valve on top of the block and the isolation valve on the side. Process and instrument connections are 1/2" NPT (F); the drain / vent is offered at 1/4" NPT (F) or 1/2" NPT (F), which is the widest drain choice in the PTM series.
A drain plug is available as an option, as is a three piece union for positioning the gauge. Two mounting bolts to IS 1364-1960 are supplied with the manifold.
