Premium quality Ball Valve range from X2 Valves

X2CDBFV model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with a centric disc construction and is available in wafer type body paten. The body liner which also functions as the soft seat, comes in either a replaceable version or an integrally moulded (bonded) version and offers -100 % bi-directional sealing against full vacuum to rated pressures of PN10 or PN16. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

Benefits & Application

  • Self lubricated PTFE bearings for both drive end and non-drive end shaft ensures minimum bearing friction torque.
  • Seat liner extending on to the flange contact faces, eliminates the need for separate flange gaskets during installation.
  • Bi-directional valve with tight shut-off sealing capability to hold vacuum to rated pressure in either direction Suitability for ON/OFF as well as throttling duties. Catalogue
  • Choice of seat and disc materials to suit media conditions and service requirements.
  • Excellent adaptability for actuated operation through standardized top flange mounting dimensions for actuator fitment.
