Tyco Valves and Controls has introduced a series of new, butterfly valves for general purpose industrial applications, the PremiSeal range. The PremiSeal range is designed for use across a range of industrial applications, providing a wafer thin disc for excellent flow characteristics and head loss. Available in a wafer or lugged configuration, PremiSeal provides bubble-tight shut-off control in both directions, and is also suitable for end-of-line duties up to 16 bar. Available with either a parallel flat or square shaft drive, PremiSeal is ideally suited for use with the range of Tyco PremiAir pneumatic actuators or TVC electric actuators but is also available in a manually operated design. The standard valve configuration consists of a ductile iron body and a stainless disc. The valve seat is available in either EPDM or Nitrile Rubber.
