A Cepex UPVC diaphragm valves are a type of industrial valve used for precise flow regulation in corrosive or high-purity fluid applications. Manufactured under Cepex's "Extreme Series," they are designed for reliability and chemical resistance. 

Key features

• Materials: The valve body is constructed from PVC-U (unplasticized polyvinyl chloride), with membranes typically available in EPDM or FPM (Viton®). The right material choice depends on the specific chemical and temperature requirements of the system.
• Performance: The valves are engineered for:
  • Precise flow regulation: Allowing fine control over the fluid's volume and speed.
  • Minimal pressure loss: Ensuring efficient fluid transfer with little pressure drop.
  • Corrosion resistance: The PVC-U body offers excellent resistance to a wide range of inorganic chemicals.
  •  
• Operating specifications:
  • Sizes: Available in a range of sizes, including D20 (DN15) to D63 (DN50).
  • Pressure rating: Nominal pressure rating is PN10 at 20°C (73°F).
  •  
• Configurations: Cepex offers several connection options to fit various piping systems:
  • Female solvent socket (socket fusion)
  • Female threaded ends (BSP, NPT)
  • Flanged ends
  • Butt welding ends (for PE100)
• Actuation: While manual options are standard, Cepex also produces automated versions with electric or pneumatic actuators.
• Quality assurance: Cepex valves undergo a 100% water pressure test at the factory to ensure reliability and are certified with the CE mark.
