Pneumatic Wafer Knife Gate Valve

Valve Body

a) The knife gate valve adopts an integrated ultra-thin body design with a full-bore flow channel. This effectively minimizes medium leakage, reduces flow loss, lowers costs, and facilitates easy installation and operation.

b) The bottom of the valve body flow channel uses fixed guiding claws to secure the gate plate, replacing the traditional groove design. This prevents medium accumulation and avoids jamming when closing the valve.

Gate Plate

a) The bottom of the gate plate adopts a knife-shaped arc design, which provides excellent shearing capability and superior sealing performance when the gate moves. It is particularly suitable for controlling pulp and media containing fibers.

b) The gate plate is equipped with PTFE point-guided supports, which reduce friction and prevent damage to the plate.

c) The thickness of the gate plate can be increased based on actual pipeline pressure requirements.

Valve Seat

a) The valve adopts a replaceable seat design (non-integrated sealing). When the sealing surface is worn, only the valve seat needs to be replaced, making maintenance easier, extending the overall valve service life, and reducing equipment operating costs.

b) The replaceable valve seat is secured and preloaded using a seat cover. When sealing performance decreases, the sealing effect can be improved by adjusting the seat cover fixing screws.

Others

a) The dual-bearing design reduces valve torque, making opening and closing smoother and easier.
