Diaphragm valve CK

pneumaticpneumatically-operatedcompact

Overview
The CK/CP is a pneumatically actuated diaphragm valve with an innovative, extremely compact design. It is the evolution of the CM/CP series, offering improved reliability, durability and versatility. Designed for demanding industrial applications, the CK/CP combines compactness, lightness and high performance to ensure safe and long-lasting operation even in heavy-duty conditions.

Key benefits

• Very compact full-plastic construction suitable for installations in confined spaces.
• New compact and lightweight piston actuator designed for very frequent operations and long valve life.
• Operating life exceeding 1 million cycles (laboratory tests).

What makes the CK/CP unique?

• Compressed air inlets adjustable by 90° to align connections with the piping according to plant configuration, simplifying installation and integration.
• Anti-unscrewing actuator system to prevent piston rotation, extending diaphragm life and enabling maintenance-free operation.
• Fully integrated sealing diaphragm within the valve body to guarantee optimal rubber compression without lateral expansion.
• Innovative circular rib integrated into the valve body that enhances the diaphragm sealing system by promoting outward compression, maximizing sealing efficiency and eliminating the risk of leaks under pressure.

10 key features

• Valve body with socket connection available in PVC-U, PVC-C, PP-H and PVDF.
• No metal parts in contact with the fluid or the environment.
• New range available in four materials to suit different chemical compatibilities.
• Safety guaranteed by DualBlock® technology to prevent actuator nut loosening.
• Total installation flexibility thanks to 90° adjustable air inlets.
• New diaphragm seal fully integrated into the valve body, protected against distortion.
• Maximum effectiveness of the external sealing system thanks to a circular rib integrated into the valve body.
• Compatible with a wide range of chemicals.
• Ideal for industrial applications, dosing and sampling.
• Compact and lightweight design for easy installation even in confined spaces; flow rate increased by an average of 10% compared to the previous CM/CP series.

Applications

• Designed for demanding industrial applications, including dosing and sampling systems where frequent actuation and long maintenance-free life are required.
