Grooved valves

Groove gate is the introduction of the European high-tech production of rubber and valve manufacturing technology, overcome the rubber aging and rust and other defects. The valve using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, grooved gate is the introduction of the European high-tech production of rubber and valve manufacturing technology, overcome the rubber aging and defects such as rust. The valve using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, this valve has the switch light, reliable sealing, good elastic memory and long life and other significant advantages, the products are widely used in tap water, sewage, sea water, water treatment, environmental protection, construction, fire protection, petroleum, chemical, electric power, food, medicine, textile, shipping and energy industries such as pipeline online as regulation and river closure device. Flat type seat

General valve after water flushing tube is often due to the external things such as concrete, iron and other debris sedimentation on the bottom of the valve groove, easy to cause cannot close tightly and form slack phenomenon, at the bottom of the seal gate valves of the elastic base seat USES the same flat as the pipeline design, not easy to cause debris deposition, make the flow unimpeded. The body of the precision

The body is made of precision casting, and the precise geometry size makes it possible for the valve to be sealed without any processing at any time. Valve plate plastic bags

Survey on the valve plate is made of high quality rubber plastic bags, inside and outside the first-class rubber vulcanization technology make the valve plate after vulcanization can ensure accurate geometry size, and rubber and nodular cast iron valve plate then, fall off not easily and elastic memory preferred. "O" ring sealing ring

Due to the valve stem and valve cover adopt three type "O" ring sealing ring seal design, can reduce the frictional resistance when switch, can significantly reduce leakage phenomenon and medium flow in the pipeline for the replacement seals. Help to raw drink

Due to the inner body with non-toxic, epoxy resin coating, both internal and external surfaces of the valve plate with rubber lie without completely molten iron or corrosion phenomenon, to drink. Labor-saving devices

DN450-600 - mm, with labor-saving devices separately, the required torque is about half of the normal, only a small hand wheel, under stressful circumstances, can be fully open or close operation, the energy saving device in every action, to restore energy function after the valve fully open first. This is the introduction of groove gate valves.
