Differential Pressure Control


V03 manifold/valve assemblies provide isolation and control in systems equipped with Ashcroft 1132 and 1133 differential pressure gauges. Available in 3 or 5 way configurations, these stainless steel manifolds permit removal of the gauge without disrupting the process. They also allow hi and lo side equalization prior to startup to eliminate damaging hi-side spikes. 1132 and 1133 gauges can be direct mounted or remote mounted via a capillary or hard tubing.
