2-Valve Manifolds

2-Valve Manifolds

Two-valve manifolds are compact valve assemblies designed specifically to isolate, vent, and calibrate pressure-measuring instrumentation within industrial process control applications. Constructed from robust materials such as stainless steel, these manifolds integrate two separate valves—usually one isolation and one vent valve—into a single, streamlined unit. This combination simplifies the setup and maintenance of instruments like pressure transmitters and gauges, ensuring safe and reliable operation.

The primary advantage of two-valve manifolds is their ability to enhance operational safety and measurement accuracy. By integrating isolation and vent valves into one assembly, they significantly reduce potential leak paths and facilitate easy isolation and depressurization of instruments. This enables maintenance technicians to safely calibrate, inspect, or replace pressure instrumentation without interrupting the primary process, minimizing downtime and enhancing overall system reliability.

Industries frequently utilizing two-valve manifolds include oil and gas, chemical processing, petrochemical refining, power generation, pharmaceuticals, and water treatment facilities. In these industries, accurate pressure measurements and reliable instrumentation performance are critical for maintaining process safety, product quality, and operational efficiency.

Applications for two-valve manifolds include isolating pressure gauges and transmitters, safely venting trapped fluids or gases during calibration and maintenance activities, and providing secure connection points for instrumentation in high-pressure process systems.
