Three manifold configurations for every process requirement.

All BETLOCK manifolds can be designed and manufactured according to specific process requirements — custom configurations on request.

● BLOCK & BLEED

2 Valve Manifold

Isolate and drain a pressure instrument from the process.

Block (isolation) and bleed (vent/drain) valves in one body
Ideal for gauge pressure and absolute pressure transmitters
Integral and remote mount configurations
Compact, lightweight — lower installation cost
Available in high-pressure versions up to 420 Bar

● BLOCK & BLEED

3 Valve Manifold

Isolate, equalize and vent for differential pressure transmitters.

Two block valves + one equalize/bypass valve
Ideal for DP flow, level and pressure transmitters
Enables calibration without process shutdown
T-Type, H-Type and Coplanar flange designs
Process conn: ½" NPT or ½" BSP (M/F)

● FULL FUNCTION

5 Valve Manifold

Full block-bleed-equalize-calibrate function in one compact body.

Two block + two bleed + one equalize valve
Safe isolation, calibration and zero check without removal
Ideal for critical DP measurements in hazardous areas
Integral or remote mount — vertical or horizontal flange
Flanged per IEC 61518 / DIN 19213 available

Integral or remote — to suit any installation.

Integral Mounting

Block & Bleed design
T-Type (top) mounting
H-Type (horizontal) mounting
Coplanar flange design (DIN / ANSI)
Vertical flange design
Direct mount to transmitter — eliminates impulse tubing

Remote Mounting

Pipe-to-Pipe (NPT Female) design
Used where transmitter is remote from process tap
Allows flexible installation routing
Instrument connection: ½" NPT (M/F), ½" BSP (M/F)
Flanged per IEC 61518/B / DIN 19213
