The SS-M2F8 five-valve manifold is an integrated instrument manifold specifically designed for use with differential pressure transmitters, integrating two isolation valves (high pressure and low pressure), two drain/vent valves, and one equalizing valve into one compact body. Featuring female threaded connections (typically NPT 1/2” female threads) and precision internal flow paths, it enables connection or isolation between the transmitter's high/low pressure chambers and the impulse lines, equalization between the two chambers, and draining/venting of accumulated condensate, gas, or impurities inside the manifold. This manifold is primarily used for differential pressure transmitter root isolation, online zero calibration, equalizing operations, draining/venting, and system venting. Its core purpose is to achieve safe isolation of differential pressure, flow, or level measurement systems, online transmitter maintenance, and draining/venting without interrupting process operation, thereby ensuring continuous, stable operation and measurement accuracy of automated control systems.

1. Five-valve integrated design: Integrates two isolation valves, two drain valves, and one equalizing valve into one body, offering compact structure, comprehensive functionality, and significantly reduced leakage points.

2. Full-function operation: Coordinated operation of the five valves enables normal commissioning, zero calibration, online isolation, draining/venting, and system venting, meeting diverse on-site maintenance requirements.

3. Specifically for various differential pressure transmitters: Widely compatible with 3051, 1151, EJA series differential pressure transmitters with strong compatibility.

4. Female thread connections for easy installation: Both ends feature standard female threads (e.g., NPT 1/2”), ensuring convenient connection and reliable sealing.

5. Metal-to-metal hard seal for reliability: Tapered or spherical hard seal between disc and seat ensures wear resistance and long cycle life.

6. All-stainless steel construction: Body and internal components made of high-quality stainless steel (304/316) for excellent corrosion resistance in various industrial media.

7. High pressure capability and wide temperature range: Nominal pressure up to PN16-PN40 or higher, temperature range from -70℃ to 570℃, suitable for medium to high temperature, high pressure, and complex media applications.
