Overview

The working principle of the Ouyan electric gate valve DN250 is driven by the motor of the electric actuator. After being decelerated by the reducer, it drives the valve stem to make a linear motion of rising or falling, thereby controlling the opening and closing of the gate. When the gate is lifted, the valve opens and fluid can pass through; When the gate descends, the valve closes, preventing fluid from passing through.

Product Details

1、 Electric gate valves are suitable for cutting off or connecting pipeline media in various systems of petroleum, chemical, hydraulic, and thermal power plants with a nominal pressure of PN1.6~16.0MPa and a working temperature of ≤ -29 ℃~550 ℃. Applicable media include water, oil, steam, acid, alkali, ammonia, urea, sulfur-containing natural gas, etc. The operation modes include manual, gear transmission, electric, pneumatic, etc.

IIOuyan Electric Gate ValveStructure and Characteristics of DN250

1. The selection of materials is meticulous, in compliance with relevant domestic and international standards, and the overall quality of the materials is high.

2. Meets the requirements of domestic and international standards, with reliable sealing, excellent performance, and beautiful appearance.

3. The sealing surfaces of the gate and valve seat are made of cobalt based hard alloy with different hardness by welding, which ensures reliable sealing, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, and long service life.

4. The valve stem has undergone quenching and surface nitriding treatment, exhibiting excellent corrosion resistance, abrasion resistance, and wear resistance.

5. Adopting a wedge-shaped elastic gate structure, thrust bearings are installed on the medium and large diameters, with low friction, and equipped with manual impact for easy and smooth opening and closing.

6. Various piping flange standards and flange sealing surface forms can be adopted to meet various engineering needs and user requirements.

IIIOuyan Electric Gate Valveworking principle

The working principle of an electric gate valve is driven by the motor of an electric actuator, which, after being decelerated by a reducer, drives the valve stem to move in a straight line up or down, thereby controlling the opening and closing of the gate valve. When the gate is lifted, the valve opens and fluid can pass through; When the gate descends, the valve closes, preventing fluid from passing through.
