Orifice Plate Choke Valve

Orifice Plate Choke Valve

The orifice plate choke valve utilizes a rotary fork to drive the valve seat assembly, requiring only a 90-degree or 180-degree rotation to easily open and close the valve. Both ends of the fork are pre-tightened to enhance fork stiffness, minimize vibration, and ensure smooth, safe operation. By pairing with hydraulic, pneumatic, and electric drive devices, the orifice plate throttle valve achieves more accurate adjustment, making it widely used across industrial applications.
