valve has a light switch, reliable seal, the elastic memory of good and long life.
Overview:
Has long been used on the market in general gate valve, the prevalence of leaks, rust easily phenomenon, the enterprises to introduce foreign advanced technology produced by soft sealing gate valve. Overcome the general gate valve seal fatigue flexibility, easy to rust and other defects. Soft sealing valve is a new generation product of traditional gate valve, the flexible gate the role of micro-deformation compensation to achieve a good sealing effect, the valve has a light switch, reliable seal, the elastic memory of good and long life, significant advantages can be widely used in water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, fluid lines, as the regulation and closure devices.
• flat style seatThe traditional gate valve often through the washing tube after siltation due to foreign objects such as stones, wood, cement, paper and other debris on the valve end of the groove. Easily cause can not be closed tightly and the formation of water leakage, soft sealing gate valve, the lower part of the same flat design and pipes, less prone to debris deposition in, so that the fluid kept clear
• The overall package glueThe valve plate within the overall outsourcing glue, after the curing of the domestic first-class rubber vulcanization technology makes the valve plate to ensure accurate geometric dimensions of high quality rubber, and rubber and ductile iron gate connected firmly, not falling, and good elastic memory.
• corrosion-resistantValve body with a powder epoxy coating to prevent corrosion and rusting of the body, can be used for the sewage system.• difficult to fragmentationThe past, traditional cast iron gate valve often park hit by foreign objects, collision or overlap caused by the fracture phenomenon. As the valve switch to ductile iron, such cases could be substantially reduced.
• three "O" ring seal"0" ring seal valve stem seal design can reduce the friction resistance when the switch to substantially reduce the leakage phenomenon of lightning can turn off the water construction to replace the seals.
• The casting bodyThe body uses the precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve.
• help to drinkRust water or corrosion due to internal body with non-toxic epoxy resin coating, the gate of the inner and outer surfaces are rubber coated completely which is not available to drink.• LightweightThis valve uses a spheroidal graphite cast to reduce about 20% -30% lighter in weight than traditional gate valve weight. Installation and maintenance.
