TianKang HongJi QFF3 Three Valve Manifold

TianKang HongJi QFF3 Three Valve Manifold assembly is a connection and operation device used between differential pressure measuring instruments - such as differential pressure gauges, differential pressure transmitters or differential pressure meters - and the process piping. It can perform basic operations such as isolation, balancing (equalization) and venting/discharge, facilitating the maintenance, calibration and safe shutdown of the instruments.

TianKang HongJi Coplanar Three Valve Manifold

TianKang HongJi Coplanar Three-Valve Manifold, engineered and manufactured by Hongji Instrument & Valve Manufacturing Co., Ltd., integrates multiple valve functions into a single, compact unit with versatile connection options. This robust and precision-crafted manifold plays a critical role in process instrumentation by enabling direct and indirect support for pressure measurement devices—including pressure gauges, pressure transmitters, and differential pressure transmitters. Through its efficient bleeding, blocking, and calibration capabilities, the manifold ensures accurate measurement and equalization of various pressure types—such as differential, static, gauge, and variable pressures—across industrial process lines. Designed for reliability and ease of operation, it enhances system safety, simplifies maintenance, and improves calibration workflows, making it an essential component in modern automation and control systems.

TianKang HongJi Integral Three Valve Manifold

The TianKang HongJi Integral Three-Valve Manifold from Hongji Instrument & Valve Manufacturing Co., Ltd. is a precision-engineered valve assembly that integrates three critical functions—blocking, bleeding, and equalizing—into a single, compact body. Designed as a central control point for pressure instruments like gauges, transmitters, and differential pressure transmitters, it ensures system safety and operational efficiency. This manifold enables safe isolation, pressure equalization to protect sensitive DP cells, in-line calibration, and venting, all while minimizing leak points and simplifying maintenance in process instrumentation lines.
