Product Description

 

Product Description

Introduction:

Gate valves with high/medium pressure flange connections are suitable for petroleum,chemical, and power pipelines, with pressures of PN1.6-16.0 MPa and temperatures ≤-29°C to 550°C. They cut off or connect media like water, oil, steam, acids, alkalis, and natural gas. Operation modes include manual, gear, electric, and pneumatic.

 

 

Structural features:

 

• Premium material selection: Compliant with domestic and international standards, ensuring high-quality materials.
• Advanced design: Meets global standards, offering reliable sealing, excellent performance, and an aesthetically pleasing appearance.
• Optimized sealing pair: The gate and seat sealing surfaces are welded with Stellite cobalt-based hard alloy of varying hardness, ensuring reliable sealing, high hardness, wear resistance, high-temperature resistance, corrosion resistance, anti-scuffing properties, and extended service life.
• Treated valve stem: Quenched, tempered, and surface-nitrided for superior corrosion resistance, anti-scuffing properties, and wear resistance.
• Efficient structure: Features a wedge-type elastic gate design, with thrust bearings for medium and large diameters to reduce friction, and an impact handwheel for smooth and effortless operation.
• Versatile compatibility: Supports various piping flange standards and sealing face types, meeting diverse engineering needs and customer requirements.
