GB flange gate valve

Overview：

National standard flange gate valve refers to a type of gate valve that complies with Chinese national standards (GB). It adopts a flange connection method (fixing the valve to the pipeline flange with bolts), and its valve disc moves vertically along the center line of the valve seat, controlling the opening and closing of the pipeline through the "fully open" or "fully closed" state. The core functions are:

◆ Cut off medium flow: When fully open, the fluid resistance is extremely low, and when fully closed, the sealing performance is excellent, suitable for scenarios where flow rate adjustment is not required.

◆ Bidirectional sealing: Some models can achieve bidirectional pressure sealing, and there is no need to strictly limit the flow direction of the medium during installation.

Nominal diameter：10mm～2000mm and 1/2"～80".

Working pressure：0.25MPa～76.0MPa/150Lb～4500Lb/10K～320K.

Adopting standards：GB, DIN, API, ANSI, JIS, BS, etc.

Drive mode：Manual, worm gear transmission, pneumatic, electric, hydraulic, etc.
