Product Details

The piston ring type sleeve regulating valve adopts sleeve guidance and pressure balanced valve core. It is suitable for high-temperature working conditions. The sturdy sleeve guidance and the unique metal piston ring provide high stability for the up and down movement of the valve core, reducing vibration and mechanical noise. This series of regulating valves have excellent dynamic stability and are high-performance regulating valves suitable for high-pressure working conditions. Due to the structure that balances the fluid pressure acting on the valve core, it only requires a small operating force to achieve stable regulation.
