1 CP KWWA Soft Seat Knife Gate Valve for Water Works Donghae Co., Ltd.

2 Donghae Co., Ltd. DONGHAE We will come closer to our customers with advanced technology and quality. Donghae Co., Ltd. has been specialized in manufacturing Knife gate valves since its foundation. With abundant experience and continuous efforts to develop the technology, we have introduced a leak-free water gate valve (soft seat and plate-type disc structure) that goes beyond the limits of knife gate valves that have been applied only for limited and special applications such as chips and powders. Our patented technology, soft seat water gate valve has no leakage when shutting off(ansi 150LB & 300LB(JIS 10K & 20K) applicable). It not only solves the persistent problem of the valve which has been applied to the existing waterworks, but also shows both performance and economical advantages as there is no foreign substances buildup on the bottom of the valve port and it has the bonnet structure not allowing leakage to the outside of the body. This soft seat knife gate valve is supplied to all fluid lines such as rectification line, gas line, marine shipbuilding, power plant as well as water supply and drainage line, and has been recognized for its quality. It is a valve with sufficient competitiveness as an alternative to gate valve, ball valve and butterfly valve, which are in high demand for valves. Dong Hae Co., Ltd will do our best to develop technology and improve quality in order to give back to customers support.

4 SOFT SEAT KNIFE GATE VALVE No leakage Features DONGHAE SOFT SEAT & PLATE-TYPE DISC TYPE 04 It satisfies domestic and overseas standard requirements ; * KWWA-CP Confirmity Product Certificate of Knife Gate Valve for Water Supply * Water Valve Compliance Criteria * SPS-KWWA B Standard for Water Soft Seal Sluice Valve * SPS-KVIC Stainless Steel Sluice Valve * KS B 2332 Sluice Valve Standard * KS B 2334 Ductile Cast Iron Sluice Valve Standard * MSS SP-135 High Pressure Knife Gate Valve Standard Zero Leakage even at high pressure with double sealing of soft seat and metal seat Applies to all fluid lines including pure water, a mixture of sludge and water Leakage protection is possible at all times as there is no foreign substances buildup on the bottom of the valve port. Price is competitive as material requirements are low with narrow interfacial structure, and it is easy to install even in a narrow space. Reduced packaging and shipping costs due to its light weight. Advantageous in cost reduction as it is possible to operate with a small driving force, so that a smaller specification actuator can be applied. Reduced repair costs as valve seat, soft seat, can be removed and attached. When the valve is closed, the disc first touches the soft seat and then contacts the metal seat. So lifespan of valve is expended preventing wear of the disc and soft seat. Essential valve for water supply and drainage line because there is no leakage to outside of valve and it is advantageous to make clean environment.
