Electric Gate Valve

The electric gate valve is composed of electric actuator and wedge gate valve. The work is driven by electric power, and the electric actuator drives the valve stem to do lifting motion. Electric actuator has torque control mechanism, field operation and hand/electric switching mechanism. Besides on-site operation, it can also carry out over-distance operation, PLC control, 4-20MA current input and output intelligent control, etc.

Application:

Water, sewage, construction, petroleum, chemical, food, pharmaceutical, textile, electric power, shipbuilding, metallurgy, energy systems, etc.

Product introduction:

The electric gate valve is a kind of gate valve. The driving method of the electric gate valve is electric actuator. The connection method is flange type, welded type and clip type.

Structural characteristics of electric gate valve

1. The ram has two sealing faces. The most common is that the two sealing faces of the ram form a wedge shape, and the wedge angle varies with the valve parameters, usually 5°.

2. The sealing principle of the electric gate valve is achieved by the tight combination of the two sealing faces on the wedge gate and the two sealing faces on the valve body when wedged.

3. Electric gate valve, American standard wedge valve can be divided into open gate valve (lifting gate valve) and dark gate valve (rotating rod gate valve) according to the different ways of opening and closing the valve stem.

4. According to the different structure of the ram, the electric gate valve can be divided into an elastic ram gate valve and a rigid ram gate valve.

5. The valve body is cast and molded, the valve body and the valve cover are bolted, and the middle flange is sealed with a wound gasket. When the customer has special requirements, the metal ring can also be used for connection.

6. The channel is smooth and the flow coefficient is small. The sealing surface is less scoured and eroded by the medium.

7. The sealing surface is made of alloy steel or hard alloy, which has good wear resistance and scratch resistance.

8. It adopts flexible graphite packing, which is reliable in sealing and light and flexible in operation.

9, the flow direction of the medium is not limited, no disturbance, no pressure reduction.

10. The shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide.

Advantage:

1. The use of equal-diameter straight-through structure with runner greatly reduces the loss of flow resistance coefficient and energy, and significantly improves the service life and performance of the valve.

2. The valve chamber adopts pressure self-tightening sealing structure, which has good sealing performance.

3. The sealing surface of gate and seat is made of cemented carbide surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and abrasion resistance.

4. The surface of the valve stem has good corrosion resistance and abrasion resistance after corrosion-resistant nitriding treatment.

5. The structure of hoist can be designed into single board, double board and parallel double board according to user's requirements.
