This product is made by means of importing the high-tech rubber and the know-how of valve manufacture of Europe and over comes the defectives as rubber aging and rust etc., It uses the compenseating actiion ftrom the micro-deformation of elasticity produced by the elastic gate plate to get the good sealing effect and features the advantages of light on-off, reliable sealing, good memory of elasticity, long duration and so on. It can be used as the adjust and shutoff device on the popeline in tap water, sewage,seawater,water treatment, environmentAl protection, construction, petroleum, chemical indystry, electric power, food medicine, light & textile industry, ship, energy source etc. industries.

For the common gate valves, it is easy to make it unable to tihgtly close the valve and thus resulting in leakage after being rinsed with water because of the foreign matters such as stones, wood blocks, cement, ferric bits, sundry things etc. Which are piled up inside of the concave slot on the valve bottom. The elastic-seat enclosed gate valve uses the same design of flat-bottom as that of the pipeline so as not to be easy to get sundry matters piled up thus making the fluid smoothly flowing without any resistance.

This valve is made of high-quality Ductalloy, resulting in a reduction of weight by about 20%-30% of that of the traditional ones and an easy installation and service.
