The piston-actuated throttling valve, also known as the piston valve, is a type of control valve that uses a piston mechanism to control the flow of fluid. It consists of a cylindrical housing with a piston inside that moves up and down to regulate the fluid flow.

When the piston is in the closed position, it blocks the flow of fluid, and when it is in the open position, it allows the fluid to flow through. The position of the piston can be adjusted to control the flow rate within a desired range.

This type of valve is commonly used in industries such as oil and gas, chemical, and power generation, where precise control of fluid flow is crucial.

Product description:

LT942X piston flow regulating and pressure regulating valve is a speed regulating and pressure regulating valve developed by our technical staff based on the advanced experience of Germany and Japan, summarizing domestic design, manufacturing and practical experience, and according to the characteristics of fluid mechanics. It has been widely used in power stations, water diversion, water supply and other fields. The improved flow regulating valve of this series is not only suitable for clean water, but also has good tolerance for natural river and lake water and light sewage. From the design structure and material selection, the problems that the flow regulating valve is easy to scale, jam and the driving device is too large have been solved for many years.

Features：

This valve is superior to the traditional flow regulating valve in that its structural design and material selection make it not afraid of sewage clogging the slideway, not afraid of fouling, and not easy to jam. The drives are significantly smaller. The valve can automatically adjust the preset pipeline medium parameter value to keep it constant within a certain accuracy, and the accuracy range can also be adjusted. The valve has good cavitation resistance, and the ribs on the inner wall of the valve also function as a rectifying plate, which can disperse the water flow and prevent cavitation. At the same time, the noise of the valve and the vibration of the piston are also reduced. The degree of control and precision requirements are not very high,the control of the valve can be in manual or common electric form. The water flow section at any position in the valve body is a ring structure.
