Rising Stem Hard Seal Groove Gate Valve

• 

Product Overview:
The Rising Stem Hard Seal Groove Gate Valve is a high-performance designed strictly in accordance with national standards and inspired by advanced international models. This valve is engineered for full open or full close functions, not for throttling, and is widely applied in high-reliability pipeline systems requiring robust sealing and safety.

Key Features:

• Optimized Structure: Compact, safe, and attractive design based on foreign models, with enhanced tensile and compressive strength.

• Integrated Sealing Surface: Oxygen welding technology forms the valve plate and body as a copper alloy whole, minimizing friction, preventing deformation, and ensuring stable operation at varying temperatures.

• Low Torque Operation: The copper-to-copper contact reduces friction, ensuring light and easy opening and closing.

Technical Specifications:

• End Connection: Flange (ANSI150LB / GB / BS Standard)

• Stem Material: 2Cr13 / Stainless Steel

• Bonnet & Body Material: Ductile Iron QT450

• Seal Material: Ductile Iron QT450 + NBR Rubber

• Surface Finishing: Epoxy Red or Blue
