  • The manifolds provide, in a single body, 3 or 5 valves for differential pressure measurement applications. This compact, industry standard-sized design results in fewer leaks to the environment. These manifolds have large 3/8″ (9.5mm) bores connecting the process and instrumentation sides. The manifolds are available in Pipe by Pipe, Pipe by Flange, Flange by Flange configurations with inline or right-angle process flows in stainless or carbon steel.  Kerotest manifold valve accessories, such as mounting stabilizers, stabilizers with integrated block valve, dielectric isolation kits, and vent plugs help complete the product line and needs of our customers.
