The Proseal range of Butterfly valves is available in a wide range of sizes and materials and provides a cost effective solution where valves are required for utility type applications. The valve has an easily replaceable cartridge type liner comprising a rubber seat with a phenolic backing. The cartridge is pressed into the body, secured by means of the shaft and is therefore blow out proof and particularly suited for use on vacuum applications. The thickness of the rubber seat is optimised, therefore reducing possible swelling, and the hard phenolic backing minimises distortion of the rubber when tightening the valve between flanges. These design features ensure that the valves operate with the minimum torque requirement, and mean that, unlike those with loose liners they can be installed with the blade in the closed position, thus eliminating any possibility of damage to the blade during installation. The splined drive between the disc and the shaft is free from media ingress and possible corrosion therefore the shaft is easily withdrawn and the valve easily stripped irrespective of the time that the valve has been in service.

Features:

  • Low torque, especially important when actuating
  • Cartridge type liner means seat is easily replaced
  • Optimised seat thickness means less swelling and reduced torque
  • Wide range of sizes and materials
  • Available in wafer pattern and lug type
  • Shaft ends available in square, double D and splined configurations
