Steam-thermal oil system valves

Bellows sealed globe valves are emission-free and maintenance-free. A continuous metal barrier is located between the pipeline and the environment. Components that undergo relative movements during valve operation are welded to the ends of a metal bellows that absorbs and compensates for movement. Therefore, these valves are suitable for any fluid and are recommended when zero emission performance is required to protect the environment and workers' health from contaminating leaks, to prevent costly waste due to wasted energy and fluid, and to eliminate significant costs. replacement of packaging. In conclusion, the valves are especially suited for hazardous, flammable, deadly and explosive environments.

Molten salt valve

The molten salt valve series developed by WEIKE is based on the requirements of molten salt valves for solar thermal systems, and is an improvement on the bellows valves that Van Loon has considerable experience in designing and producing. The improvements are reflected in the structure to prevent salt leakage from the middle flange, the heat tracing system to prevent molten salt crystallisation at the bellows, and the reasonable selection of materials.
The molten salt valve includes two categories of molten salt stop valve and molten salt regulating valve, which are used in solar thermal power generation systems where molten salt is used as the energy storage medium.

Toxic and hazardous media valves

Weike developed a special valve for toxic and hazardous media - bellows shut-off valve, suitable for transporting flammable, explosive, permeable and radioactive media, especially in the transport of thermal media heat transfer oil more zero leakage advantage, the use of multi-layer seal, excellent performance, is to create a green factory quality products, for special gas pipeline transport, such as chlorine, ammonia, gas, hydrogen, natural gas, etc., is a best choice

Bellows gate valve

The bellows gate valve is designed to form a metal barrier between the fluid medium and the atmosphere by automatic roll welding, ensuring zero leakage from the stem. The bellows gate valve has an internal bellows structure with the lower end of the stainless steel bellows welded to the stem by a stainless steel gasket to prevent the process fluid from corroding the stem. The other end is placed between the valve body and the valve cover to form a static seal. The double seal design avoids leakage if the bellows fails to fill the stem, and the bellows is welded to the stem to maintain a stable operating performance and avoid stem vibration due to flap vibration. Most suitable for steam, flammable, explosive, thermal oil, high purity, toxic and other media in the pipeline.

Control valve

Widely used for precise control of gas, liquid and other media process parameters such as pressure, flow, temperature and level to maintain a given value. They are particularly suitable for applications with high flow rates, large differential pressures and high leakage requirements.
