Field Adjustable Pressure Reducing (URFA)

Transcription

1 IL JUSTL PRSSUR RUING 10-1 ield djustable Pressure Reducing (UR) lkhart s UR valve is a true pressure reducing valve, operated automatically by inner hydraulic controls. While the valves are preset at the factory, they are field adjustable allowing you to tailor the pressure to your needs. They feature manual valve open and close, as well as pressure adjustment all of which require extremely low torque to change due to the patent pending design. Inlet pressure up to 400 psi (27.58 bar) is controlled under all flow and no-flow conditions. Valve size and weight permit installation in significantly tighter areas and smaller hose cabinets (those used for 1 1 /2 or 2 1 /2 valves) allowing savings of both space and money. The UR also functions as a floor control valve in automatic sprinkler systems as well as a standpipe valve or hose valve for lass I and lass III systems. UR Series valves not intended for use in salt water applications.

3 PRSSUR RUING 10-3 Pressure Reducing (Pressure-Matic) lkhart s Pressure-Matic is a true pressure reducing valve, operated automatically by inner hydraulic controls. No diaphragms, springs or outside controls are involved with the unit, the action being completely dependent upon conditions at the nozzle or sprinkler system. lkhart rass offers 18 different valve pressure types/ranges for building systems. Inlet pressure up to 400 psi (27.58 bar) is controlled under all flow and no-flow conditions. The UR valve series may be used as a standard shut-off. The valves are completely tamperproof. They fit all existing cabinets where 1 1 /2 or 2 1 /2 valves are currently in use. Pressure-Matic valves can be used for/in: loor ontrol Valve Standpipe System utomatic Sprinkler Systems UL Listed as a check valve for use in dual riser systems Visual Status Indicator Optional Supervisory Switch racket 400 psi rating UR Series valves not intended for use in salt water applications.
