Z61Y High Temperature High Pressure Power Plant Pressure Seal Bonnet Gate Valve
Product Description
Z61Y High Temperature High Pressure Power Plant Pressure Seal Bonnet Gate Valve
Introduction
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.
