FREE-Valves Bi directional knife gate valves are known as slurry gate valves. Its are bidirectional valve deals with flow in both directions, while offering zero leakage. The U shape peripheral seat design ensures full-port flow and non-clogging shutoff.The disc bottom of knife gate valve is made into a blade shape with the purpose to cut some soft materials such as fiber,pulp or wood pulp, and it also serves favorable closing and opening. Features: 1) Knife gate valve is Bi directional,zero leakage,withstanding high differential pressure and full bore valve with minimal seat cavity for maximum flow capacity. 2) No groove is designed on the valve seat,which prevents accumulating media on the sealing surface, and thus avoids sealing surface leakage or disc blockage cause by media accumulation. 3) The integrated body structure with precision casing. 4) U shaped resilient seat is embed into the body and is well connected with the gate,and the friction is reduced during the upward and downward movements of the gate.This greatly prolongs the using life of the seat and realized bi directional sealing. 5) Replaceable flexible wire reinforced elastomer seat ensures bi-directional zero leakage shutoff. 6) Full port flow path with minimal pressure drop achieved through full port valve design.

Mining, coal washing, iron and steel industry used for washing coal pipes, filter slurry pipes, discharging ash pipes, etc. 2. Purification system used for waste water, mud, sewage and water with suspended solids. 3. Paper industry used for any mixture of pulp, material and water of any concentration.
The knife gate valve is truly a high performance knife gate valve design. This valve provides zero leakage Bi-directional shut-off, has mechanically retained seal, has a compact non-rising stem design, and can be Repacked in service under full pressure. The chest and seating areas of the valve are self-cleaning. The Reduced chest area, minimal gate arc, and contoured flushing corners in the body prevent jamming by Eliminating material build-up in the chest, body and seating area. The gate seals against a combination Metal and resilient seat and is guided for the full stroke length of the valve. The top “transverse” seal is repackable while in service under full pressure. The valve is tested and rated for zero leakage (liquid or Gas) downstream and to atmosphere.
PZ Series Knife Gate Valve This series knife gate valve is a kind of gate valve, it is straight stroke cut off valve, the knife gate valve gate head has oblique cutting edge, has certain cutting effect to the medium, can be equipped with manual, pneumatic, electric actuator, widely used in papermaking, mining, chemical, sewage treatment and other process automatic control system.
