Designed specifically for pressure gauges: Compact structure allows direct installation at the pressure gauge root, facilitating online removal, calibration, and maintenance.
Threaded connections for easy installation: Both ends feature standard threaded ports (such as M20×1.5, G1/2, NPT1/2) matching pressure gauge and pipeline interfaces, ensuring simple installation and reliable sealing.
Needle-type disc for precise regulation: The needle disc cooperates with the seat to enable precise adjustment and control of small flow rates with excellent regulation performance.
Metal-to-metal hard seal for reliability: Sealing surfaces are directly machined from stainless steel, forming a wear-resistant metal-to-metal hard seal with long service life.
All-stainless steel corrosion resistance: Body and main components are made of 304/316 stainless steel, providing excellent corrosion resistance for various corrosive media.
High-pressure design: Robust body structure withstands high working pressures, suitable for high-pressure applications.
Reliable stem sealing: Multi-layer packing or PTFE sealing with gland prevents external leakage.
Compact structure for space adaptability: Small size and light weight make it ideal for space-limited installations.
