Flat seat of the valve through the washing tube after often due to foreign objects such as stones, wood, cement, paper, debris and siltation in the valve end of the groove, likely to cause can not be closed tight and the formation of water leakage. The soft sealing gate valve at the bottom of the same flat design and pipes, not easy to cause the debris deposition in the fluid kept clear. 
 The overall package plastic valve with high quality rubber within the overall outsourcing glue, making the domestic first-class rubber vulcanization vulcanized valve to ensure accurate geometry, and then solid rubber and ductile iron valve, easy to fall off, and flexible good memories. 
 Corrosion-resistant body with powder epoxy coating to prevent corrosion and rusting of the body, and can be used for the sewage system. 
 Is not easy to fragmentation of the past, traditional cast iron gate valves often hit by foreign objects, touch Shan or overlap caused by the phenomenon of fracture. The body to switch to ductile iron, this is the case can mate the degree to reduce. 
 Three "O" type 
 Ring seals the valve stem to the three "O" ring ring seal design can reduce the frictional resistance of the switch to substantially reduce water leakage and can not stop water construction to replace the seals. 
 Will help to drink because of the internal body rubber completely non-toxic epoxy resin coating, the gate of the inner and outer surfaces are coated and will not appear rusty water or corrosion, available to drink. 
 Body casting body uses precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve. 
 The light weight body with spheroidal graphite cast is made to reduce about 20% to 30% lighter in weight than traditional gate valve weight, easy installation and maintenance.
