TianKang HongJi Integral Five Valve Manifold(Differential pressure gauge)

The Hongji Integral Five Valve Manifold is a precision-engineered assembly that consolidates five valve functions into a single, robust body, serving as a critical control hub for differential pressure measurement systems. It is specifically designed to interface directly with differential pressure transmitters, enabling safe and accurate measurement of differential, static, and line pressures. Through its integrated configuration, the manifold provides essential capabilities for pressure equalization—effectively protecting the sensitive diaphragm of the DP transmitter—as well as for instrument isolation, impulse line venting (bleeding), and in-line calibration. This all-in-one design not only streamlines complex operational procedures but also significantly enhances system safety by minimizing potential leak points, thereby ensuring reliable performance and extended service life for your critical process instrumentation.



Overview

Integral five valve manifold made by Hongji Instrument& Valve Manufacturing Co., Ltd. combine several valves in one body with multiple connections. This equipment assists pressure instruments such as pressure gauges, pressure transmitters, and differential pressure transmitters directly and indirectly in measuring and equalizing pressures, differential pressures, static, gauge, and variable in process instrumentation lines by bleeding, blocking, and calibrating.

Applications

  • In the Oil & Gas sector, they enable accurate pressure measurement, secure isolation of high-pressure lines, and safe calibration of transmitters during drilling and refining operations. Chemical and Petrochemical Plants depend on them for precise process monitoring, allowing safe equalization and isolation during reactor and distillation control.
  • Within Power Generation, manifolds support reliable instrumentation by managing the measurement and isolation of steam and water pressure in boilers and turbines. In Pharmaceutical and Biotechnology processes, they ensure sterile and contamination-free fluid control by providing clean isolation and controlled venting during maintenance and validation.
  • For Water Treatment, valve manifolds regulate and monitor pressure across filtration and distribution systems, ensuring stability and efficiency. In HVAC applications, they simplify system isolation, aid in pressure balancing, and enhance maintenance safety for refrigerant and chilled-water circuits. Meanwhile, Laboratories and Research Facilities rely on them for precise differential pressure measurement, calibration, and controlled fluid routing in analytical or testing setups.
  • Their capability to isolate, equalize, and vent pressure instruments safely and accurately makes valve manifolds indispensable for maintaining operational safety, measurement accuracy, and system reliability in any process environment.
