high quality standard rising stem seal gate valves /gate valves manufacturers/gate valves for water/knife gate valves

 rising stem seal gate valves elastic base 

The traditional gate valves are often in the wash out water is for external things such as stone, wood, cement, the paper scraps, sundry etc deposition in the bottom of the valve in the groove. Easy to cause the cannot close close and the formation of slack phenomenon, seal gate valves with elastic base at the bottom and conduit of the same flat design, is not easy to cause sundry deposition, make the fluid unimpeded.

· overall plastic bags

Valve plate adopts the high quality rubber in the whole, outsourcing glue, the domestic first-class rubber vulcanization technology makes the valve plate after sulfide to ensure accurate geometry size, and rubber and nodular cast iron disc connecting firm, is not easy to fall off and elastic memory preferred.

· corrosion resistance

The valve body the epoxy coating powder, can prevent the body the corrosion and rust, and can be used for sewage system.

· is not easy to break

Before traditional iron gate valves is often caused by external things hit, collision or overlap and cause fracture wait for a phenomenon. Because this valve to switch to nodular cast iron, the situation has been greatly reduced.

· three O type ring seal

Because stem the use of three 0 type ring sealing ring seal design, can reduce the friction resistance when switch cuts, slack phenomenon and can not replace the sealing ring water supply construction.

· help born drink

Because the body with non-toxic inside the epoxy coating, the inside of the disc surface are coated with rubber completely without water or corrosion phenomena appear rust, born to drink.

· light weight

This valve USES the nodular casting and become, weight is traditional gate valves about 20%-30% weight. Easy installation and maintenance.
