Supply of the dark bar gate trench

Flat-style seat traditional gate often through water pipes after foreign objects such as stones, wood, cement, paper, and other debris deposition in the valve bottom groove. Unable to close tight and likely to cause the formation of water leakage, soft seal valve lower part using the same flat pipe design, easy to siltation caused by debris, the fluid unhindered. ? Whole package plastic valve plates made of high quality rubber within the overall outsourcing glue, rubber vulcanization domestic first-class technology allows the valve plate after vulcanization can ensure accurate geometry, and rubber and ductile iron gate connection secure, easy to fall off and good elastic memory. ? Corrosion valve body using epoxy powder coating to prevent corrosion and rusting valve can be used for wastewater system. ? Help to drink due to the valve body with a non-toxic epoxy resin coating, inner and outer surfaces are rubber shutter completely covered and will not appear rust or corrosion of water available to drink. ? Light weight of the valve using ductile cast, lighter in weight than the conventional valve about 20% -30%. Easy installation and maintenance. ? Easy to fragmentation of traditional cast iron gate outside the park was hit often, overlapping fracture caused by a collision or other phenomena. As the valve is switched to ductile iron, such a situation has to be drastically reduced. ? Three "O" ring seals due to the valve stem with three "0" ring ring seal design, can reduce the friction resistance switch, significantly reducing water leakage lightning can stop water construction to replace the seals.
