Valve manifold is a standard accessory for pressure transmitter and differential pressure transmitter. By providing a valve manifold in the instrument, it will allow a calibration or change the instrument without the necessity of plant shutdown. In particular application there are three type of valve manifold, 2-way valve manifold, 3-way valve manifold, and 5-way valve manifold.
The 2 valve manifold,2 way manifold valve Fig N.20MN3131EB6021 Series is a line-mounted two valve manifold that functions as a shutoff and bleed valve for static pressure instrumentation. Compared to traditional piping methods that use an arrangement of nipples, pipes, elbows and tees, and gate valves, the Series will provide a low cost, easy-to-install unit that performs the same functions traditionally performed by a number of piping components. The use of the HM59 Series also reduces the number of threaded connections, resulting in fewer leak points.
3 valve manifold ,3 way manifold valve Fig N.30MN3131AB6026 Series is a general purpose instrument manifold designed for connecting differential pressure transmitters or flow records to impulse line tubing. Connections are 1/2" NPT on industry standard 3-2/8" center-to-center dimensions (models for 2-3/16" and 2-1/4" center-to-center dimensions are also available).
For differential pressure applications, the 5 valve manifold,5 way manifold valve Fig N.50MN3131EB602X performs the block and equalizing functions of a standard three valve manifold and provides two additional block valves to be used for blowdown purposes. To blow down the impulse lines, the block valves on the manifold are closed, and the two blowdown valves are opened, allowing the impulse lines to be blown out through the ports on the lower side of the blowdown valves.
This series of manifolds combines double isolate (Primary and Secondary) and bleed vent in a combination of ball
and needle into one block, for interface with pressure measurement transmitters, gauges and switches for
applications up to 10,000psig (689 barg).
A variety of end connections can be provided including NPT as standard with optional BSPT and BSPP. Kp-lok can also combine single or twin ferrule integral fitting technology into the product offering the end user the benefit of
leak path reduction and contaminant free connections by eliminating taper threads.
