2 Way Manifold Valve Manufacturer in India – Instrumentation Manifold Valves

Forxar Industries Pvt. Ltd. is a trusted 2 Way Manifold Valve Manufacturer in India, offering precision-engineered instrumentation manifold valves designed for pressure isolation, controlled venting, and safe maintenance of pressure measurement instruments.

A 2-Way Manifold Valve, also known as a 2 Valve Manifold, Double Valve Manifold, or Block and Bleed Manifold, is used in pressure instrumentation systems to control the connection between a process line and a pressure gauge or pressure transmitter.

A typical 2-way manifold incorporates two separate valve functions: one for isolating the process pressure and another for controlled venting or bleeding of pressure from the instrument side.

This compact arrangement allows operators to isolate pressure instruments for inspection, calibration, replacement, and maintenance without unnecessarily disturbing the main process piping.

Forxar 2-Way Manifold Valves are engineered with precision-machined flow passages, suitable sealing components, and carefully selected materials to support reliable pressure control and instrumentation performance.

Our industrial instrumentation manifolds are suitable for oil and gas, petrochemical, chemical processing, power generation, hydraulic systems, and other demanding industrial applications.

How Does a 2-Way Manifold Valve Work?

A 2-Way Manifold Valve typically contains two independently operated valves within a single manifold body.

The first valve acts as an isolation valve, controlling the process pressure connection to the measuring instrument.

The second valve provides a bleed or vent function, allowing controlled release of trapped pressure from the instrument side after the process connection has been isolated.

During normal instrument operation, the isolation valve is generally open and the bleed valve remains closed.

For maintenance, the process connection is isolated first. The instrument side can then be depressurized through the bleed connection using the approved site procedure and a suitable discharge arrangement.

This configuration simplifies pressure instrument maintenance and helps reduce the number of individual components required around the instrument.

However, a two-valve manifold should not automatically be treated as a double-block-and-bleed arrangement. Additional isolation requirements may apply for hazardous services and critical maintenance tasks.
