CCKZXY Direct-Acting Pressure Regulating Valve

Category: CCK Series Self-Actuated Control Valve

Summary:The CCKZXY-1 direct-acting pressure regulating valve with a shut-off function requires no external piping—instead, the medium flows directly through the valve core and is throttled by the valve seat before entering the lower diaphragm chamber of the actuator. The force exerted by the medium on the diaphragm pushes the valve core toward the closed position. Meanwhile, the opposing force from the spring enables the actuator to move, establishing a dynamic equilibrium. By adjusting the regulating screw, the setpoint can be modified to achieve stable pressure control. This valve is ideally suited for applications such as micro-pressure automatic regulation of gases in various industrial furnace combustion systems, petroleum refineries, oil depot protective gases, and heat treatment protective atmospheres.

The CCKZXY-1 direct-acting pressure regulating valve with shut-off function eliminates the need for external piping; instead, the medium flows directly through the valve core and is throttled by the valve seat before entering the lower diaphragm chamber of the actuator. The force exerted by the medium on the diaphragm pushes the valve core toward the closed position. Meanwhile, the opposing force from the spring enables the actuator to move, establishing a dynamic equilibrium. By adjusting the regulating screw, the setpoint can be modified to achieve stable pressure control. This valve is ideally suited for applications such as micro-pressure automatic regulation of gases in various industrial furnace combustion systems, petroleum refineries, oil storage facility protective gases, and heat treatment protective atmospheres.

　　The CCK series self-operated control valve requires no external power source, instead using the energy inherent in the controlled medium itself as its driving force. It incorporates an actuator to precisely regulate the position of the valve core, thereby adjusting the pressure differential and flow rate across the valve and maintaining stable upstream (or downstream) pressure. This self-operated control valve is composed of key components such as the valve body, valve core, valve seat, stem, and diaphragm cover. It features finely segmented pressure ranges that overlap seamlessly, delivering exceptional control accuracy. Primarily designed for pressure reduction, relief, and stabilization of gaseous, liquid, and steam media, these valves are widely used across various industrial applications—including petroleum, chemical processing, power generation, metallurgy, food production, and light manufacturing—making them a versatile solution for critical process control needs.
