The Z45X gate valve adopts the integral coating of the valve plate to produce deformation compensation and achievegood sealing effect.It overcomes the phenomenon of poor seal,leakage and rust of general gate valve,and saves installationspace more effectively.Can be widely used in tap water,sewage,construction,petroleum,chemical industry,food,medicine,textile,electric power,ship,gold,energy system and other fluid pipeline as a regulating and intercepting device used.The softseal gate valve adopts no cavity structure,the inside and outside surface of the valve body valve cover is sprayed with epoxyresin,and the surface of the gate plate is coated with rubber,so the possibiity of corrosion is fundamentally eliminated.Thevalve stem seal is replaced by an”O”sealing ring,which makes the sealing more reliable.
