Valve blocks

A valve block (manifold) serves for connection of pressure gauges, differential pressure gauges, pressure transducers and differential pressure transducers to the process. The compact design of valve blocks with connections for generally 2, 3 or 5 valves offers different instrumentation possibilities for functions such as shut-off, blow-off, bleeding or zero point calibration in one instrument and in a minimum of space.

Valve Blocks and Pressure Gauge Shut-off Valves – M Series

Application

M Series valve blocks are suitable for process pressures of up to 410 bar (6000 psi) and temperatures of up to 648°C (1200°F). The valve blocks are available in versions for direct installation or for in-line installation. M Series valve blocks are also available for use in systems with sour gas applications.

Flexible Instrumentation with Differential Pressure Measurement

Hy-Lok D M Series valve blocks offer connections for 2, 3 or 5 instruments for direct installation or in-line installation with PTFE or Grafoil seal materials for high-temperature applications. In addition to valve blocks, Hy-Lok offers pressure gauge shut-off valves and an extensive range of accessories, such as needle valves with different openings, adapters or screw fittings.
