Forged Steel Electric Power Station Globe Valve

Brief introduction:
 
Middle part of pressure seal globe 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 to clients' requirements
Medium can be high temperature and high-pressure water, steam, oil products and super-heated steam
Widely used for the thermal power plant, petrochemical industry, metallurgy and other industrial sectors

Main features:

1. Central connection adopt pressure self-tightening structure

2. Disc and seat are welding with hard alloy

3. High temperature creeps resistance design

4. Material of stem is precipitation hardening stainless steel by nitriding

5. Operating device can be manual, gear, bevel gear and an electric actuator
