RBVS Universal Ball Valve Switch

The Potter RBVS Universal Ball  Valve Switch is designed to monitor the fully open position of a ball valve installed in a sprinkler system. The unit will fit on most ball valves installed on backflow preventers and alarm trim lines of dry, alarm, and deluge sprinkler valves. The switch operates if the ball valve handle is moved from the open position. A cover tamper switch is available and is activated by the removal of the RBVS housing cover. If an attempt is made to remove the RBVS by the removal of the mounting brackets, the unit will be set into the tripped mode by this action.

Engineering Specs

           

Ball Valve Supervisory Switch:

UL, cUL Listed and FM Approved supervisory switch specifically manufactured for monitoring ball valves shall be furnished and installed on ¼ turn ball valves that can be used to shut off the flow of water to a portion of the sprinkler system including the trim piping on alarm check or dry pipe valves.

Locations shall be as indicated on drawings and as required to comply with the requirements of section 903.4 of the IBC and IFC as well as the requirements of NFPA 72.

The supervisory switch shall monitor the position of the handle on the valve and be capable of monitoring a valve in the open or closed position. Movement of the valve handle from normal shall activate the supervisory switch. Restoration of the valve handle shall cause the supervisory switch to automatically restore to normal. There shall not be any tools or extra steps required to restore the supervisory switch to normal. The enclosure shall be corrosion resistant and rated NEMA 4. The cover of the device shall be secured by the use of a tamper proof screw. All mounting hardware necessary for the installation on valves ranging in sizes from ½” – 2” including backflow preventers shall be included. Each ball valve switch shall contain 1 SPDT contact rated 10A at 125/250 VAC and 2A at 30 VDC.  Ball valve supervisory switch shall be model RBVS as manufactured by Potter Electric Signal Company, LLC.

Additional information for Engineers:

  • The RBVS allows for easy compliance with the international building & fire codes
  •            
  • The trim on all dry pipe, wet alarm check and preaction valves provides a shut-off valve to the pressure type waterflow switch.
    Note:If the valve is closed, a waterflow alarm cannot be initiated.


Installation Tips

  • The plunger of the RBVS switch should be in direct contact with the metal handle of the valve. It may be necessary to cut away part of the rubber handle coating.
  •            
  • Try to locate the plunger where the valve handle is least likely to flex or bend.
  •            
  • The cover tamper switch version RBVS-T is not necessary. The cover is held in place with tamper proof screws like all other Potter products.
  •            
  • Another reason not to use the cover tamper switch is that wiring space is limited.
