CCKZXY-2 Direct-Acting Pressure Regulating Valve

Category: CCK Series Self-Actuated Control Valve

Summary:The CCKZXY-2 direct-acting pressure-opening type pressure regulating valve 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 creates a tendency for the valve core to open. This force, combined with the counteracting force from the spring, drives the actuator and establishes 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.

Product Details

The CCKZXY-2 direct-acting pressure regulating valve opens directly without the need for external piping. 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 creates a tendency to open the valve core. This force, combined with the counteracting force from the spring, drives the actuator and establishes 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 employs 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 pressure either upstream or downstream. 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 fine, overlapping pressure adjustment ranges and delivers exceptional precision in regulation. Primarily designed for applications involving gas, liquid, and steam—specifically for functions like pressure reduction, pressure relief, and pressure stabilization—the valve is widely used across various industrial sectors, including petroleum, chemical processing, power generation, metallurgy, food production, and light industry.
