More information
Omniprocess 316/316L stainless steel valve blocks combine block & bleed, equalisation and venting in a single compact hub. All models are test-pressurised to 1.5 × max pressure (630 bar) and comply with NACE MR0175 for corrosive media.
IV series - block & bleed for pressure sensors
- IV01 - easy shut-off (1 needle valve) for pressure gauges and transmitter lines.
- IV02 - block & bleed (2 valves) allows safe calibration without process interruption.
Both models come with ¼″ NPT ports, non-rotating stem tip and metallic body-to-hood seal for bubble-tight closure up to 420 bar / 200 °C.
MD Series - 3 & 5 way differential pressure manifold
- MD31D - 3-way configuration (2 cut-off + 1 equalisation) for routine zeroing of DP transmitters.
- MD51D - 5-way variant with dual bleed valves; ideal for live calibration & sampling.
Compatible with most DP sensors via direct flange. Stuffing box in PTFE (standard) or graphite for up to 450 °C.
MP series - monoflange with rotatable adapter
MP21 "Pancake" combines an O.S.&Y process valve with secondary shut-off and optional venting in an ultra-compact monoflange. 360° swivelling adapter allows you to orientate the manometer for optimal reading.
