Angle Type Two Valve Manifold
Angle Type Two Valve Manifold from SIYelectric is designed to integrate multiple valve functions into one compact manifold body, providing reliable isolation, venting, bleeding, and calibration support for industrial pressure instruments.
It is commonly used with pressure gauges, pressure transmitters, differential pressure transmitters, and other process instrumentation devices. By allowing operators to block, bleed, equalize, or calibrate the pressure line, the manifold helps improve measurement safety, maintenance efficiency, and long-term instrument reliability in demanding process applications.
Applications
Oil & Gas Industry
Pressure monitoring and control
Used in drilling, production, pipeline, and refining systems to support the measurement and control of high-pressure liquids and gases.
Flow measurement support
Installed together with pressure or differential pressure instruments to assist flow monitoring in pipelines, process units, and refinery applications.
Isolation, venting, and draining
The two valve manifold allows instruments to be isolated safely from the process line, making inspection, venting, draining, and calibration easier in high-pressure service.
Chemical and Petrochemical Plants
Process pressure control
Suitable for pressure instrument connections in reactors, pumps, distillation columns, dosing systems, and process pipelines.
Safety and maintenance
Provides a controlled way to isolate instruments from aggressive or high-pressure media, helping reduce maintenance risk and improve operational safety.
Power Generation
Steam and water systems
Used in boiler, turbine, feedwater, condensate, and steam line instrumentation where stable pressure measurement and safe isolation are required.
Instrumentation protection
Helps protect pressure transmitters and gauges during commissioning, calibration, shutdown, and routine maintenance.
Pharmaceutical and Biotechnology
Controlled fluid measurement
Can be used in auxiliary process lines, clean utility systems, and instrumentation loops where controlled isolation and pressure measurement are required.
Hygienic process support
For applications with cleanliness requirements, suitable material selection and connection design should be confirmed according to the actual process medium and cleaning conditions.
Water Treatment and Distribution
Flow and pressure regulation
Used with pressure instruments in filtration systems, pumping stations, distribution pipelines, and water treatment units.
Easy maintenance
Allows instruments to be isolated without shutting down the entire pipeline section, improving maintenance convenience.
HVAC Systems
Pressure and temperature system support
Applied in chilled water, heating water, refrigerant, and ventilation-related control systems for pressure monitoring and instrument isolation.
Service isolation
Makes it easier to maintain or replace pressure gauges and transmitters in complex HVAC piping systems.
Laboratories and Research Facilities
Precise fluid control
Used for gas and liquid pressure measurement lines in testing equipment, pilot systems, and laboratory process skids.
Multi-point instrument connection
Supports controlled routing, isolation, and calibration of pressure instruments in experimental or research environments.
