Knife-type Gate Valve Series

Our company produces 4 series of knife gate valves, which are suitable for pipelines with pressure of 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.0Mpa, and 150LB. They are widely used in papermaking, mining, infrastructure and other industries.

Double-piece Bidirectional Seal Knife Gate Valves

The valve body of LGD series knife gate valve is of double-piece closed design, which attains the machining of the inner cavity of the valve body, and the valve body can be fully lined with rubber or polyurethane. This product has passed ISO5208-2.0Mpa test and obtained 0 leakage rating.
It adopts the patented 45-degree fit of the gate edge and sealing surface, which strengthens the sealing of the valve without increasing the opening torque, and realizes a good performance of 0 leakage in the middle cavity after 5,000 times gate opening and closing test.

Lug Type Bidirectional Seal Knife Gate Valves

LGS series knife gate valves are bidirectional seal valves. The valve body is made of ductile iron, which has corrosion resistance. The valve body is designed with a patented slot to ensure light opening and closing torque. After embedding the rubber seal, it can fulfil 8,000 times of gate opening and closing without the seal coming off. The product has passed ISO5208-1.0Mpa test and obtained 0 leakage rating.

Knife Gate Valve With Cover

DMZ series knife gate valves are unidirectional seal valves and are conventional general-purpose valves. Both hard and soft seals are available, and ceramics can be embedded as seal. The product enhances the pressure-bearing capacity in the middle cavity through the valve cover.With the purging hole design on the valve cover, it can prevent ash from the inner cavity clogging after long-time use.

Rising Stem Quincuncial/Circular Knife Gate Valves

PZ43/73 series knife gate valves are unidirectional seal regular knife gate valves with good versatility. Both hard and soft seals are available, and ceramics can be embedded as seal. This product is widely used in slurry and slag discharge pipelines in medium and low temperature conditions, and is a cost-effective product.
