Electric welding gate valve, welded gate valve, gate valve

Product Overview of Electric Welding Gate Valve:

In some pipelines, there is a certain interchangeability relationship. The middle part adopts a pressure self-tightening type without a valve cover, which has excellent sealing performance under high-temperature and high-pressure conditions. There are two types of self-sealing rings, one made of low-carbon steel and the other made of 316 flexible graphite wire (mesh). The upper layer of the sealing surface is welded with drill-based hard alloy, and the processed pure metal layer is ≥ 3mm, which is wear-resistant, resistant to high temperature, corrosion-resistant, resistant to scratching, and has a long service life. The ends of the branch pipe are welded structures, and the welding groove can be made according to standards or user requirements. Suitable for use in pipelines transporting water, steam, oil products and superheated steam in thermal power plants, petrochemical plants, metallurgical plants, etc., under high temperature and high pressure conditions.

Advantages of the electric welding gate valve product:

1. Central pressure self-tightening connection without valve cover

2. Gate plate is of wedge-type elastic single gate plate or wedge-type double gate plate structure

3. Both the gate plate and valve seat are double-sided hard alloy clad

4. Design resistant to high-temperature creep

5. Valve stem is made of nitrided precipitation hardening stainless steel

6. Available in manual, gear (sun gear and regular gear) transmission, and electric versions

This electric welding gate valve is of no-flange pressure self-tightening type and has excellent sealing performance under high-temperature and high-pressure conditions. There are two materials for the self-sealing ring, one is low-carbon steel, and the other is 316 flexible graphite wire (mesh). The upper layer of the sealing surface is welded with drill-based hard alloy, and the processed pure metal layer is ≥ 3mm, which is wear-resistant, resistant to high temperature, corrosion-resistant, resistant to scratching, and has a long service life. The ends of the branch pipe are of welding structure, and the welding according to the groove can be made according to standards or user requirements. It is suitable for pipelines in high-temperature and high-pressure environments such as thermal power plants, petrochemicals, metallurgy, etc., for water, steam, oil products, and superheated steam.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition

Overview of the electric welding gate valve product:

The electric welding gate valve is a valve without a flange that uses pressure self-tightening mechanism. It has excellent sealing performance under high-temperature and high-pressure conditions.
