Electric gate valve from the valve operating force larger than pneumatic, pneumatic valve switching speed can be adjusted, simple structure, easy maintenance, action process due to the cushioning properties of gas itself is not easy to get stuck due to damage, but there must be gas source, and its control system is also complicated than the electric valve. The electric flange valve response is sensitive, safe and reliable, and many factories with high control requirements set up the compressed air station for the pneumatic instrument control components. Electric is a device that requires electricity and can control its flow. The electric flange wedge valve is a kind of linear motion gate valve. It is composed of Z multi rotary actuator, which has the switch type and the intelligent type. The valve operation is the most common open and close valve, which uses the up and down work of the gate to connect and turn off the fluid medium in the pipe. It is widely used in power, metallurgy, petroleum, chemical, papermaking, sewage treatment and other departments. It is mainly used to connect – truncate or adjust the medium in the pipeline.
Electric flange gate valve product advantages:
1, the fluid resistance is small, the sealing surface is scoured by the medium and the erosion is small (the opening of the gate is high).
2, the opening is more powerful, the sealing performance is good, the flow direction of the medium is not restricted, the flow is not closed, the pressure is not reduced.
3, the form is simple, the manufacturing process is good, the scope of use is wide, Shanghai Yi Fan valve specialized product.
Electric flanged gate valve features:
1. The material is well chosen and in line with the relevant standards both at home and abroad. The material has high overall quality.
2. According to the requirements of advanced standards at home and abroad, the seal is reliable, excellent in performance and beautiful in shape.
3, the seal pair is advanced and reasonable, and the sealing surface of gate and valve seat is made of alloy with different hardness. The sealing is reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance and long life.
4, the stem is treated by quenching and tempering and surface nitriding. It has good corrosion resistance, abrasion resistance and wear resistance.
5, the use of the wedge type elastic gate structure, medium and large caliber thrust bearing, friction force is small, and equipped with impact manual, open and close easy.
6. All kinds of pipe flanges and flange seal faces can be used to meet the needs of various projects and users.
