DIN ductile iron resilient seated gate valve

German standard resilient seated gate valves

Features:Flatbed seat - the traditional gate valve are often through the washing tube after by 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 tightly and the formation of leakage phenomenon, 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 glue of the overall package - high-quality rubber valve within the overall outsourcing glue, making the domestic first-class rubber vulcanization vulcanization after the valve to ensure accurate geometry, then solid rubber and ductile iron valve, not falling and good elastic memory.Corrosion-resistant - Body Powder epoxy coating to prevent corrosion and rusting of the body, and can be used for the sewage system. Difficult to fragmentation of the past, traditional cast iron gate valve are often hit by foreign objects, collision or overlap caused by the fracture phenomenon. The body to switch to ductile iron, this is the case can mate the degree to reduce.Three "O" ring seal - stem three type "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.Help to drink - due to internal body rubber completely non-toxic epoxy resin coating, the gate of the inner and outer surfaces are coated and thus will not rust water or corrosion, available to drink.The casting body - the body uses the precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve.Light weight - the body ductile cast made to reduce about 20% to 30% lighter in weight than traditional gate valve weight, easy installation and maintenance
