PESB
Glass-Filled Nylon Globe Valves

Primary Applications:

Industrial-strength glass-filled nylon globe valve with self-cleaning scrubber and stainless steel screen for reliable performance in dirty water applications. The PESB series incorporates patented scrubber technology.

Features and Benefits:

• Durable glass-filled nylon construction for long life and reliable performance.
• Globe configuration.
• Normally closed, forward flow design.
• Slow closing to prevent water hammer and subsequent system damage.
• 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 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
• Low flow operating capability for a wide range of applications.
• Stainless steel studs molded into the body. Bonnet can be attached and removed more easily and more often without damaging threads.
• Nylon scrubber scrapes a stainless steel screen to clean and break down grit and plant material. Prevents debris build-up and clogging.

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

Rain Bird recommends flow rates in the supply line not to exceed 7.5 ft./sec. (2,3 m/s) in order to reduce the effects of water hammer.

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.

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.
