STT15-150-D Forged steel right-angle stop valve

Short Description:

Forged steel right-angle stop valve is a kind of valve whose closing piece moves vertically along the center line of the passage. It is widely used to cut off or throttle the medium in the pipeline in the pharmaceutical, chemical, metallurgical, electric and other industries. In the process of using forged steel stop valve, because the valve stem of forged steel stop valve has a relatively short opening or closing stroke, its cut-off function is very reliable, and the change of valve seat opening is in direct proportion to the stroke of valve disc, which is very suitable for flow regulation. Therefore, the function of forged steel stop valve is not only to cut off, but also to regulate or throttle.

Working Principle

Forged steel stop valve is the most widely used valve. The reason why it is widely popular is that the friction between sealing surfaces is small, relatively durable, the opening height is small, easy to manufacture, and easy to maintain. It is not only suitable for medium and low pressure, but also for high pressure. Its closing principle is to make the sealing surface of the valve clack and the sealing surface of the valve seat closely fit with the pressure of the valve rod to prevent the flow of medium. Forged steel stop valve only allows one-way flow of medium and has directionality during installation.

Characteristics

1. The valve body is integrally forged with high strength, beautiful shape and reliable material.

2. The middle chamber adopts self-sealing structure. The higher the pressure, the better the sealing. The unique stainless steel self-sealing ring is convenient for disassembly and reliable for sealing.

3. The surface of the valve rod is treated with ultra-dense wear-resistant treatment, wear-resistant and corrosion-resistant, and the opening and closing friction is small, ensuring that the product is free from leakage.
