Flow regulating valve/Piston valve
Linear Regulation for Precise Flow Control
Linear flow characteristics ensure precise flow regulation — ideal for applications requiring strict control over flow and pressure.
Low Maintenance and Extended Service Life
Optimized flow channel design and material selection ensure long service life and reduced maintenance costs.
Low Operating Force and Stable Performance
Hydraulic balance design and copper-alloy guided piston ensure smooth and stable operation with minimal driving force.
Flexible Installation for Various Pipeline Conditions
Can be installed vertically, horizontally, suspended, or at any angle — offering great flexibility for on-site layout.
Multiple Control Modes with Integrated Functions
Supports hydraulic, electric, manual, and remote operation modes. Integrates multiple functions: flow control, pressure reduction, pressure holding, regulation, and combinations thereof.
