Pneumatic Acutator Bidirectional Knife Gate Valve

Bidirectional Knife Gate Valve is a wafer knife edge gate valve used on industrial pipeline for on-off operation.

The structure of body and seat eliminates clogging shutoff for flow with fine particles. Additionally, beveled knife edge helps

the gate cut through thick media easily. According to different working situation: non-rising stem knife gate valve, wafer knife

gate valve, lugged knife gate valve, pneumatic knife gate valve, electric knife gate valve, manual knife gate valve and bevel

gear knife gate valve are all available.

Features:

1. Body:

a) Integral body with full bore structure ensures smooth flow, easy assembly and smaller shell leakage possibility.

b) Non-groove body design eliminates any potential clogging when valve shutoff.

2. Gate:

a) Beveled knife edge provides strong cutting stress and tight sealing.

b) Gate thickness can be increased to meet higher pressure.

3. Seat:

a)U-shaped elastomer seat provides a peripheral seal along the edge of the gate and ensures tight seal in both

flow directions.

4. Other:

a) Double thrust bearing minimize the torque required for operation.
