T Type Three Valve Manifold

T Type Three Valve Manifold

SIYelectric instrumentation manifolds are designed to provide safe isolation, equalizing, bleeding, venting, and calibration support for industrial pressure measurement systems.

By integrating multiple valve functions into one compact body, an instrumentation manifold helps simplify installation and maintenance for pressure gauges, pressure transmitters, differential pressure transmitters, pressure switches, and other field instruments. It allows operators to isolate the instrument from the process line, release trapped pressure, balance pressure between measurement sides, and perform calibration or inspection more safely.

These manifolds are widely used in pressure measurement, differential pressure measurement, flow measurement, level measurement, filter monitoring, and process control applications across oil & gas, chemical, petrochemical, power generation, water treatment, HVAC, laboratory, and general industrial systems.

Applications

Oil & Gas Industry

Pressure monitoring and control
Used in drilling, production, pipeline transmission, gas processing, and refinery systems where pressure instruments need reliable isolation from high-pressure liquids and gases.

Flow measurement support
Suitable for pressure and differential pressure measurement loops used to monitor flow in pipelines, refineries, separators, compressors, and process units.

Isolation, venting, and draining
Manifold valves allow operators to isolate instruments, release trapped pressure, drain residual media, and perform calibration or maintenance more safely in high-pressure service.

Chemical and Petrochemical Plants

Process pressure measurement
Applied in reactors, pumps, dosing systems, filters, distillation columns, storage tanks, and chemical pipelines where stable pressure or differential pressure measurement is required.

Safer maintenance in demanding media
The blocking, bleeding, and equalizing functions help reduce maintenance risk when instruments are installed on corrosive, toxic, flammable, high-pressure, or high-temperature process lines.

Power Generation

Steam and water systems
Used in boiler systems, turbine auxiliary systems, feedwater lines, condensate systems, and steam pipelines where pressure or differential pressure instruments require reliable isolation.

Instrument protection and calibration
Instrumentation manifolds help protect transmitters and gauges during commissioning, shutdown, zero checking, routine inspection, and calibration work.

Pharmaceutical and Biotechnology

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

Clean process isolation
For hygienic or sanitary applications, material selection, connection type, sealing structure, and surface requirements should be confirmed according to the actual medium and cleaning requirements.

Water Treatment and Distribution

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

Filter pressure drop measurement
Suitable for monitoring differential pressure across filters, membranes, and treatment units, helping operators identify clogging, fouling, or maintenance requirements.

HVAC Systems

Heating and cooling system measurement
Applied in chilled water, heating water, refrigerant, air handling units, filter sections, pump systems, and heat exchangers where pressure or differential pressure instruments require isolation.

Service and maintenance isolation
The manifold provides a convenient local service point, helping technicians inspect, calibrate, or replace instruments with less system interruption.

Laboratories and Research Facilities

Controlled gas and liquid pressure lines
Used in laboratories, test benches, pilot plants, and research systems where gases or liquids require stable pressure measurement and safe isolation.

Flexible instrument connection
The compact manifold body supports instrument mounting, pressure release, equalizing, calibration, and pressure line management in experimental or small-scale process systems.
