3-Valve DN5 Product Description
 3-Valve DN5, also named DN5 three-valve manifold, is an integrated valve assembly used with differential pressure transmitters. It is designed for pressure measurement isolation, balancing and venting operations, supporting safe maintenance of pressure measuring instruments for process equipment renovation.

This manifold delivers reliable pressure control for process measurement tasks. The pressure control integrates high-pressure valve, low-pressure valve and balance valve. The pressure control realizes isolation of transmitter from process pipeline and pressure balancing before disassembly. Stable pressure control prevents overpressure damage to differential pressure sensors.

The built-in valve body structure achieves steady media switching. The media switching completes cut-off, balance and vent operation by manually rotating valve stems. The media switching supports online calibration and safe instrument replacement without pipeline shutdown. Accurate media switching ensures pressure measurement matches site process monitoring requirements.

Compact integrated structure brings convenient pipeline installation. Pipeline installation can be directly mounted on pressure transmitter. Pipeline installation connects process pipeline and transmitter via threaded ports. Flexible pipeline installation is widely used for legacy pressure measurement system spare replacement.

3-Valve DN5 supports high pressure resistance and corrosion resistance, equipped with internal valve stem and seal structure. It adopts stainless steel material option for liquid, gas and steam media. Widely applied in chemical industry, power plant and oil & gas process measurement systems. This product is available as industrial spare parts, complying with process instrument manifold standards.
