Product Overview

Piston flow control valve is a high-performance valve for precise flow control, widely used in petroleum, chemical, electric power, HVAC and many other industries. The valve is suitable for water, steam, gas, oil and various corrosive media, with excellent high temperature resistance, corrosion resistance and pressure resistance. Piston flow control valves achieve precise flow regulation through the up and down movement of the piston in the valve body, ensuring stable operation of the system under various working conditions. The advantages of the product include high adjustment accuracy, fast response speed, good sealing performance, precise flow control, and simple structure and easy maintenance. The valve adopts the advanced automatic adjustment principle, which can automatically adjust the flow rate according to the pressure change in the pipeline, preventing the occurrence of over-flow or under-flow, and improving the system safety and operation efficiency. Piston flow control valves have a wide range of applications in industrial systems requiring high-precision flow control and high stability, and are the ideal equipment for ensuring precise adjustment of flow in piping systems.

Product Technical Characteristics

Piston type flow control, pressure control valve is a kind of valve that can meet a variety of special adjustment requirements, its adjustment function is to rely on the piston-like valve plug in the valve cavity for axial (water flow direction) movement, to control the water flow of the valve outlet area to realize.

Product Design Features

1. Unlike a butterfly valve or gate valve with a valve plate: the spool (not the plate) of a piston valve moves in the axial direction (the direction of water flow).

2. Piston valves have a piston-like opening or closing mechanism.

3. The cross-section of the water flow at any position inside the valve body is annular.
