Power Station Pressure Seal Motorized Gate Valve (GAZ961Y)

Power Station Pressure Seal Motorized Gate Valve (GAZ961Y)Product DescriptionIntroduction   The middle part of pressure seal gate valve using pressure self-tightening structure,make sure the valve has good sealing performance under high pressure and high temperature conditions,usually,the sealing ring has two kinds of material,one is low carbon steel,the other is flexible graphite+SS 316,besides,the sealing surface is welding with hard alloy,after the welding is finished,the thickness of metal layer should be 3mm or more,therefore,it has advantages of wear-resistant,temperature-resistant and anti-corrosion,greatly prolong the service life.Both ends adopt welding structure,the dimensions of welding groove can be customized on clients' requirements.The medium can be high temperature and high pressure water,steam,oil products and super-heated steam.,etc,it's widely used for thermal power plant,petrochemical industry,metallurgy and other industrial sectors.Product FeaturesThe central connection adopt pressure self-tightening structure.The disc and seat are welding with hard alloy.High temperature creep resistance design.The material of stem is precipitation hardening stainless steel by nitriding.Operating device can be manual,gear,bevel gear and electric actuator.SpecificationSpecifications.1.Design Manufacture According to JB3595. 2.Face to face According to JB3595. 3.Connection end conforms to JB3595 or user's requirements. 4.Valve check and test According to JB3595.
