One of the major issues that must be considered when designing and selecting valves is the operating temperature of the valve.

The wafer type butterfly valve is one of the most common types of valves in industrial pipelines. The structure of the wafer type butterfly valve itself is relatively small. Just put the butterfly valve in the middle of the flanges at the two ends of the pipeline, and use the double stud bolts to pass through the pipeline flanges and pairs.

Soft sealing butterfly valve usually used in medicine, chemical, petroleum, electricity, textile, paper industry .Its mainly to adjust and stopped the medium in the water and gas line .Its working temperature ≤ 80 ℃.

Plastic ball valve has the advantages of simple structure, small volume, light weight, material consumption, installation of small size, fast switching, reciprocating and rotating 90 degrees, small driving torque characteristics, for truncation, connect, adjust the line of medium, has good sealing off fluid control features and performance.

All welded ball valve is widely used in various fields, its superior quality and high performance stability is the common cast steel ball valve which can not be achieved, all welded ball valve service life is far greater than the steel ball valve, full welded ball valve is widely used in city gas, city heating, petrochemical, shipbuilding, steel, power plants and other types of pipeline, pressure regulating station equipment.

Gate valve is a widely used valve. Its closure principle is the gate sealing surface and the valve seat sealing surface is smooth,consistent with each other, it not only prevent the flow of media, but also rely on the top mold, spring or gate shape, to enhance the sealing effect. It plays a main role in the pipeline.
