Coplanar Two Valve Manifold

Coplanar Two Valve Manifold

Coplanar two valve manifold is designed for direct mounting with industrial pressure instruments, especially coplanar pressure transmitters, differential pressure transmitters, pressure gauges, and process measurement systems.

By combining multiple valve functions into one compact body, the manifold provides reliable isolation, venting, bleeding, equalizing, and calibration support for process instrumentation lines. It helps operators safely isolate the instrument from the process, release trapped pressure, and perform maintenance or calibration without unnecessary disassembly.

This type of manifold is widely used in pressure measurement, differential pressure measurement, flow measurement, level measurement, and process control applications across demanding industrial environments.

Applications

Oil & Gas Industry

High-pressure measurement support
Used in drilling, production, pipeline transmission, refining, and gas processing systems where pressure gauges or transmitters need safe isolation from high-pressure fluids and gases.

Flow and differential pressure measurement
Suitable for instrument loops where differential pressure transmitters are used to monitor flow through orifice plates, flow nozzles, or other primary elements.

Isolation, venting, and draining
The manifold allows operators to isolate the instrument, release pressure, drain the line, or perform calibration more safely in high-pressure process conditions.

Chemical and Petrochemical Plants

Process instrumentation control
Applied in reactors, pumps, distillation columns, storage systems, and chemical pipelines to support stable pressure or differential pressure measurement.

Safer maintenance in harsh media
The manifold provides controlled blocking and bleeding functions, helping reduce maintenance risk when instruments are installed on corrosive, toxic, or high-pressure process lines.

Power Generation

Steam and water pressure measurement
Used in boiler systems, turbine auxiliary systems, feedwater lines, condensate systems, and other high-pressure measurement points in power plants.

Instrument protection and calibration
Helps isolate transmitters and gauges during commissioning, calibration, shutdown, or routine inspection, reducing the risk of process disturbance.

Pharmaceutical and Biotechnology

Clean utility and process measurement
Suitable for auxiliary pressure measurement points in clean utility systems, water systems, fermentation equipment, and process skids.

Isolation for maintenance
For applications requiring hygienic or clean operation, the manifold helps isolate pressure instruments for inspection or replacement. Material, surface treatment, and connection type should be selected according to actual sanitary requirements.

Water Treatment and Distribution

Pressure monitoring in pipelines
Used in filtration systems, pumping stations, treatment units, and distribution pipelines to support stable pressure measurement.

Convenient instrument maintenance
The manifold allows pressure instruments to be isolated from the pipeline, making calibration, replacement, or troubleshooting easier.

HVAC Systems

Pressure measurement in heating and cooling systems
Used in chilled water, heating water, refrigerant, and ventilation-related control systems where pressure instruments require isolation and maintenance access.

Reduced downtime
By isolating the instrument locally, maintenance can often be carried out without affecting the entire system.

Laboratories and Research Facilities

Controlled gas and liquid pressure lines
Used in test benches, pilot plants, laboratory skids, and research systems where accurate pressure measurement and safe isolation are required.

Flexible instrument connection
The compact manifold body supports controlled routing, blocking, bleeding, and calibration of pressure measurement lines.
