Product
Direct Mounting, Equalise
Double isolate / equalise / vent block with a common drain, for general liquid and gas differential pressure measurement.
Manifolds
Direct Mounting, Equalise
Designed for general liquid and gas measurement applications on differential pressure instruments, with a common drain. It differs from the double isolate / vent block beside it by carrying an equalising valve, which is what a DP transmitter needs to be zeroed in service.
The isolation valve has a T-bar handle and the vent valve an anti-tamper handle, removed after operation — the same protection against an openable vent, which makes it suitable for hazardous fluids.
Process and drain connections are 1/4" NPT (F), 1/4" BSPT (F) or 10 mm OD tube, and the instrument connection is flanged. Four mounting bolts to IS 1364-1960 and two PTFE or Viton interface seals are supplied.
