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.

Gate valve in cast iron and ductile iron, metal seated and resilient seated, which accord with din ansi bs jis standard, it is popular used in water works.
Soft-sealing gate valve is the replacement of the traditional gate valve, the use of flexible disc produce trace deformation compensation effect, achieve good sealing effect, the valve has the switch light, reliable sealing, elastic memory and long service life etc, can be widely used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems and other fluid on the pipeline as the adjusting and intercepting device is used.
Features:
Flat-bottomed seat traditional gate valves are usually deposited in the bottom groove of the valve due to external objects such as stone, wood, cement, paper, debris, etc., after flushing the pipe with water. Cause cannot close tightly and form slack phenomenon, soft-sealing gate valve using the same as the pipe at the bottom of the flat design, not easy to cause debris deposition, the fluid flow unimpeded, the whole package glue valve plate is made of high quality rubber, within the whole outsourcing, domestic first-class rubber vulcanization technology make the valve plate after vulcanization can ensure accurate geometry size, and rubber and nodular cast iron gate connecting firm, not easy to fall off and elastic memory preferred.
The corrosion resistant valve body is painted with powder and epoxy resin to prevent corrosion and rust of the valve body, and can be used in sewage system.
Not easily broken into traditional cast iron...
