3 Valve Manifolds

A range of Straight Type 3 Valve Manifold specially manufactured for remote or separate mounting. This product is a three valve instrument manifold made from heavy duty steel and brass used to perform the block, equalizing and vent supplies of differential pressure transmitter functions. This product is uniquely designed with the inclusion of a single mounting flange that allows the transmitter to bolt directly to the manifold, which eliminates the piping of excess tubing and nipples.
