ASME Gate Valve
- Standard Compliance: Strictly designed and manufactured according to American standards such as API and ASME
- Compact Structure: Reasonable design with small installation space requirement
- Low Fluid Resistance: Smooth channel with small flow resistance coefficient and minimal pressure drop loss
- Good Sealing Performance: Sealing surface made of high-quality materials for reliable sealing
- High Strength: High valve body strength and good pressure resistance
- Flexible Operation: Small opening/closing torque for easy operation
ASME Gate Valve is a gate valve product designed and manufactured according to American standards. Its closing element is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. ASME Gate Valve can only be fully opened or fully closed, and cannot be used for regulation and throttling. The product strictly complies with American standards such as API and ASME for design, manufacturing and inspection. It features compact structure, reasonable design, good valve rigidity, smooth channel, and small flow resistance coefficient. ASME Gate Valves are widely used in pipeline systems in industries such as petroleum, chemical, power, and metallurgy, suitable for media such as water, steam, and oil.
