Integrated design: Integrates high-pressure valve, low-pressure valve, and equalizing valve into one body, offering compact structure and reduced potential leakage points.
Specifically for differential pressure transmitters: Designed specifically for use with differential pressure transmitters, allowing direct installation between transmitter and process pipelines for simplified installation and maintenance.
Standardized operation sequence: Coordinated operation of three valves enables normal commissioning, zero calibration, and online isolation of differential pressure transmitters, preventing damage from single overpressure due to misoperation.
Multiple sealing options available: Various sealing types including cone seal, ball seal, or plane seal can be selected based on application requirements, ensuring reliable sealing and long service life.
All-stainless steel construction: Body typically made of 304/316 stainless steel, offering excellent corrosion resistance for various industrial media and harsh conditions.
Flexible connection options: Inlet end can be connected to process pipelines via flange, thread, or welding; outlet end directly connects to transmitter with standardized interfaces for strong universality.
Reliable stem sealing: Multi-layer packing or PTFE sealing with gland prevents external leakage.
High-pressure design: Robust body structure withstands high working pressures, suitable for medium to high-pressure applications.
