Electric Pressure Seal Power Station Gate Valve (GAZ960Y)Product
DescriptionBrief intro. 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
FeaturesMain Features.The 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.Product
