Product Description

High Pressure High Tempereature Butt Welded Pressure Seal Gate Valve

Product Description

High Pressure High Tempereature Butt Welded Pressure Seal 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.

Product Features

High Pressure High Tempereature Butt Welded Pressure Seal Gate Valve
1. Carbon steel (WCA, WCB, WCC) Suitable for medium and high pressure valves with operating temperatures between -29 and 425 °C. For superheated steam. High temperature and low temperature oil, liquefied gas, compressed air, water, natural gas and other media.
2. Low-temperature carbon steel (LCB) Suitable for cryogenic valves with operating temperatures between -46 and 345°C.
3, alloy steel WC6, WC9 suitable for working temperature between -29 ~ 595 °C non-corrosive medium high temperature and high pressure C5, C12, C12A suitable for working temperature between -29 ~ 650 °C corrosive medium temperature High pressure valve.
4, austenitic stainless steel Applicable to the working temperature of -196 ~ 600 °C between the corrosion of any media valve.
5, Monel alloy is mainly used in valves containing hydrofluoric acid medium.
6, Hastelloy is mainly used in the valve of strong corrosive medium such as dilute sulfuric acid
7. Titanium alloy Mainly applicable to all kinds of valves with strong corrosive medium
