Features & Benefits
Complete Isolation and Venting
Two independent block valves, two bleed vents, and one equalising valve provide full DP transmitter calibration, zeroing, and removal capability.
Remote or Direct Mount
Direct mount 54 mm pattern or remote mount with tube connections to suit complex instrument rack and panel layouts.
One-Piece Barstock Construction
Solid SS316 barstock eliminates all internal threaded connections, reducing potential leak paths and improving cyclic pressure fatigue life.
Non-Rotating Tips All Valves
Every valve uses a hardened non-rotating needle tip for bubble-tight shutoff through thousands of calibration cycles.
SIL Capable Design
Valve configuration supports Safety Instrumented Systems with redundant isolation paths and venting for proof testing.
