Select the vendor below.

           






When the street main water pressure exceeds 60 psi, an approved water pressure reducing valve and strainer shall be installed in the water service pipe, near its entrance to the building, to reduce the water pressure to 50 psi or lower.  Sill cocks and outside hydrants may be left on full main pressure at the option of the owner.  For servicing water systems, up to and including 1 inches, provision shall be made to permit the bypass flow of water around the vavle back into the main when pressures, due to thermal expansion on the outlet side of the valve, exceed the pressure in the main.   Pressure reducing valves with built-in bypass check valves will be acceptable.  Approved valves shall comply with ASSE 1003 Watts Series N35B.

PEB Series
1", 1 1/2", 2" (26/34, 40/49, 50/60)

PEB Series Parts

Primary Application

Industrial-strength glass-filled nylon globe valve for commercial applications. The PEB Series is our most durable plastic valve.

Features

  • Durable glass-filled nylon construction with nylon-reinforced rubber diaphragm for long life and reliable performance.
  • Globe configuration.
  • Normally closed, forward flow design.
  • Slow closing to prevent water hammer and subsequent system damage.
  • Low flow capability for a wide range of applications.
  • One-piece solenoid design with captured plunger and spring for easy servicing. Prevents loss of parts during field service.
  • Flow control handle adjusts water flows as needed.
  • Manual internal bleed manually operates the valve without allowing water into the valve box; allows pressure regulator to be adjusted without turning the valve on at the controller first.
  • Manual external bleed permits flushing debris from the system. Recommended for system start up and after repairs.
  • Stainless steel studs molded into the body. Bonnet can be attached and removed more easily and more often without damaging threads.

Options (order separately)

  • Accommodates optional, field-installed PRS-D pressure regulating module to ensure optimum sprinkler performance.
  • Accepts latching solenoid for use with Rain Bird battery-operated controllers.
  • Optional purple flow control handle for non-potable water applications (PEB-NP-HAN). newsmall-valve.gif (1053 bytes)

Operating Range

  • Pressure: 20 to 200 psi (1,4 to 13,8 Bars)
  • Flow without PRS-D option: 0.25 to 200 GPM
    (0,06 to 45 m3/h; 0,02 to 12,60 l/s)
  • Flow with PRS-D option: 5 to 200 GPM
    (1,14 to 45 m3/h; 0,32 to 12,60 l/s)
  • Temperature: Up to 150° F (66° C)

Electrical Specifications

  • 24 VAC 50/60 cycle solenoid power requirement:
    0.41 A (9.9 VA) inrush current; 0.23 A (5.5 VA) holding current
  • Solenoid coil resistance: 24 Ohms, nominal

Dimensions

  • 100-PEB:
  • 150-PEB:
  • 200-PEB:
6 1/4" x 4" x 4"
8" x 6" x 6"
8" x 6" x 6"		 (16,5 cm) x (10,2 cm) x (10,2 cm)
(20,3 cm) x (15,2 cm) x (15,2 cm)
(20,3 cm) x (15,2 cm) x (15,2 cm)

Note: The PRS-D option adds 2" (5,1 cm) to the valve height.

Models

  • 100-PEB: 1" (26/34)
  • 150-PEB: 1¼" (40/49)
  • 200-PEB: 2" (50/60)
  • All models available with BSP threads
  1. Rain Bird recommends flow rates in the supply line not to exceed 7.5 feet/second (2,3 m/s) in order to reduce the effects of water hammer.
  2. For flows below 5 GPM (1,14 m3/h; 0,32 l/s), Rain Bird recommends use of upstream filtration to prevent debris from collecting below the diaphragm.
  3. For flows below 10 GPM (2,27 m3/h; 0,63 l/s) Rain Bird recommends the flow control stem be turned down two full turns from the fully open position.
