Flow and pressure regulating valve

Product Introduction

Our piston-type flow and pressure regulating valve is engineered for large diameter water transmission pipelines, featuring an innovative piston mechanism that delivers dual precision control of both flow rate and pressure. Ideal for water supply networks, hydraulic engineering, and industrial water systems requiring smart flow and pressure management.

Product technical features

The piston-type flow regulating and pressure regulating valve is a valve that can meet various special regulation requirements. Its regulating function is achieved by moving the piston-like valve plug axially (water flow direction) in the valve cavity to control the valve outlet area of ​​the water flow.

Product design features

1. Different from the valve plate of butterfly valve or gate valve: the valve plug (not the valve plate) of piston valve moves in the axial direction (water flow direction).

2. The opening or closing device of piston valve is piston-shaped.

3. The water flow section at any position in the valve body is annular structure

Product Structure

Piston type flow regulating valve application

1. It can be used as a discharge valve or explosion-proof pipe valve in high-end water diversion projects.

2. It can be used as a liquid level or pressure regulating valve for water source storage.

3. It can be used as a flow regulating valve in pipe network water delivery projects.

4. It can be used as a pump start protection valve or water and gas flow regulating valve in water purification or sewage treatment projects.

5. It can be used to adjust the pressure balance of the pipe network during water supply.
