The forged steel gate valve operates with a gate that moves perpendicular to the fluid flow direction. It is designed to be either fully open or fully closed, with no intermediate throttling or adjustment capability. The valve features two sealing surfaces on the gate, which are typically arranged in a wedge shape; the angle of this wedge varies depending on the valve's specifications. Forged steel gate valves can be driven manually, pneumatically, electrically, or through a gas-liquid linkage system.

TECHNICAL FEATURES

Advantages of forged steel gate valve
 

• Small fluid resistance.
• The external force required for opening and closing is small.
• The flow direction of the medium is not restricted.
• When fully open, the sealing surface is less eroded by the working medium than the stop valve.
• The body shape is relatively simple, and the casting process is better.

Disadvantages of forged steel gate valve
 

• Large External Dimensions: Forged steel gate valves require a significant installation space due to their large external dimensions and opening height.
• Sealing Surface Friction: The opening and closing process involves friction between the sealing surfaces, which can lead to scratches over time.
• Maintenance Challenges: The presence of two sealing surfaces in forged steel gate valves adds complexity to processing, grinding, and maintenance tasks.
