M Series Modulating Bronze Construction Process Control Valves

Key Features

  • Actuators in sizes 37 and 64 provide for a wide range of operating requirements.
  • Multiple-spring design reduces valve height.
  • Field reversible from "air-to-open" to "air-to-close" without disassembling the valve body.
  • Nylon-reinforced, molded EPDM rolling style diahragm provides ease of maintenance and uniform thrust throughout the valve stroke.
  • Dual stem guides with integral bearings for maximum alignment and longer life.
  • Nemur mounting rail for accessory mounting.
  • Yoke is made of cast bronze for rugged construction and long service life. Stainless steel valves use the same quality yoke with particle/silicone resin coating for superior wash down service and is FDA approved for incidental food contact.
  • Extended threads on stem allow for easy adjustment to accommodate a wide range of inlet pressures.
  • Engineered and manufactured by Parker Hannifin, the combination of stainless steel filled PTFE seals and carbon filled PTFE seals provide optimum sealing, low friction and long life for a wide variety of temperatures and services.
  • Bronze valve with union nut retention of the bonnet allows for servicing without removal from the installation.
  • Stainless steel valve with bolted flange construction allows for easy servicing without removal from the installation.
  • Plugs are hardened stainless steel for maximum protection against erosive and corrosive services with Class IV shutoff.
