gang-bang,Main parts and materials
Soft-sealing gate valve is the replacement of the traditional gate valve, the use of flexible disc produce trace deformation compensation effect, achieve good sealing effect, the valve has the switch light, reliable sealing, elastic memory and long service life etc, can be widely used in tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems and other fluid on the pipeline as the adjusting and intercepting device is used.,hidden-xxx
● Flat-bottomed seat traditional gate valves are usually deposited in the bottom groove of the valve due to external objects such as stone, wood, cement, paper, debris, etc., after flushing the pipe with water. Cause cannot close tightly and form slack phenomenon, soft-sealing gate valve using the same as the pipe at the bottom of the flat design, not easy to cause debris deposition, the fluid flow unimpeded, the whole package glue valve plate is made of high quality rubber, within the whole outsourcing, domestic first-class rubber vulcanization technology make the valve plate after vulcanization can ensure accurate geometry size, and rubber and nodular cast iron gate connecting firm, not easy to fall off and elastic memory preferred.,u-porne
