Flow Switches

 

  • VSR-CR

    The Potter VSR-CR is a vane type waterflow switch for use on wet sprinkler systems where external corrosion is a concern. It is UL Listed for use on steel pipe. Models available for pipe sizes 2" through 10". The Potter VSR series is the industry standard for flow switches for fire sprinkler systems and is compatible with the widest range of pipe schedules (5 through 40) in the industry as well as all necessary listings and approvals for installation worldwide. Please see the individual data sheets for specific information about a particular model and size, including the VSR-CR-10 for use on 10" pipe.

  • Supervisory Switches


  • PIVSU-EX-O

    The PIVSU-EX-O is designed to supervise the position of a Post Indicator or Butterfly valve in hazardous outdoor locations. The device mounts in a 1/2" NPT threaded nipple to the valve body. When properly mounted, the indicator of the Post Indicator valve or the operating mechanism of the Butterfly Valve will be pushing against the return spring of the PIVSU-EX-O so that as the valve is operated, the spring in the PIVSU-EX-O pulls the trip rod over and activates the switch. To aid with installation the trip rod length is adjustable. This device features a UL listed explosion proof switch enclosure.

  • Pressure Switches


  • NAMD

    The Nitrogen Air Maintenance Device (NAMD) is a field adjustable pressure regulating device used to keep nitrogen or air pressure at the correct level in dry pipe and preaction fire sprinkler systems. It can also be used to control pressure in dry pilot line systems of dry pilot actuated deluge or preaction valves.
    The NAMD is used in sprinkler systems with an automatically controlled compressed nitrogen or air source that is at a pressure higher than required for proper system operation. These sources can include nitrogen generators and air compressors dedicated to the fire sprinkler system and “plant” air or nitrogen systems. The NAMD includes a manual bypass that, after sprinkler system maintenance or operation, allows quick filling of the sprinkler system.
