Pneumatic Sleeve Single-Seat Control Valve

Category: CCK Series Single-Seat Control Valve

Summary:The CCKSC pneumatic/electric single-seat sleeve control valve features a sleeve-type orifice structure for its seat, allowing both the sleeve and valve core to provide dual-stage media regulation. This design minimizes damage to the valve’s internal components caused by flash vaporization, cavitation, and erosion. The valve is ideally suited for applications requiring excellent shut-off performance and handling clean fluids prone to cavitation.

Product Details

The pneumatic/electric single-seat control valve features a sleeve-type opening structure for its seat, allowing both the sleeve and the valve core to provide dual-stage media regulation. This design minimizes damage to the valve’s internal components caused by flash vaporization, cavitation, and erosion. The valve is ideally suited for applications requiring excellent shut-off performance and clean fluid control in environments where cavitation is likely to occur.

　　The valve features a simple design with a straight-through, arc-shaped flow path that ensures excellent flow capacity. It consists of key components such as the valve body, valve seat, valve core, stem, packing gland, and bonnet assembly. The flow channel is designed in an S-shaped streamline configuration, offering minimal pressure drop, high flow rates, and a wide adjustable range. Additionally, the valve core is equipped with a dedicated guide sleeve, providing a large guiding area for superior vibration resistance and smooth operation. The precise alignment between the valve seat and core ensures high control accuracy. Depending on the specific application requirements, the valve can be fitted with either a pneumatic or electric actuator, delivering compact design, small footprint, lightweight construction, robust output force, and highly responsive performance. Due to its unique single-valve-core-and-seat design, the valve experiences significant unbalanced forces acting on the core during fluid flow. As a result, this valve series is ideally suited for applications where low leakage rates are critical and where the pressure differential across the valve is relatively modest. These valves are widely applicable for controlling fluids under a variety of pressure and temperature conditions.
