220
Series Brass Valves
25–75mm
Electric and Pressure-Regulating
Models
(1"–3")
Key Features
• 15 Bar (220 PSI) maximum operating
pressure
Additional Features
• Positive O-ring seal on inlet plug prevents
leaks
• Brass and Stainless Steel Construction
• Rugged, reinforced bonnet design withstands
tough and high-pressure applications
• Forward-flow design for more precise
regulation
• Low-flow capability down to 20 LPM
(5 GPM) with EZReg® module
• Easily serviced without system removal
• Proven, encapsulated, injection-molded
solenoid with captured hex plunger and
spring
•
•
•
Precise pressure control option with compact
EZReg® dial-design (serviceable under
pressure— no need to shut down system)
Tough, double-beaded, fabric-reinforced
rubber diaphragm rated at 52 Bar (750 PSI)
burst pressure
The 220 Series brass valve from
Toro, the name says it all…15 Bar
• Pressure regulates in electric and manual
modes, serviceable under pressure
(220
PSI) toughness.
• Low-power requirement for longer wire runs
• 45cm (18”) lead wires for easy installation
•
•
•
Standard, built-in Schrader-type valve for
downstream pressure verification
No external tubing for either-electric or
pressure-regulating models
Internal downstream manual bleed keeps
valve box dry and allows for manually setting
pressure regulation.
Self-cleaning, stainless-steel metering rod
Spike Guard™ Solenoid
•
External manual bleed for system flushing
Operates on half the amperage of
standard solenoid (0.1A) which
allows for longer wire runs and
more simultaneous valves in
operation.
• Manual flow control: adjustable to zero-flow
•
Flow control independent of solenoid
• Self-aligning bonnet to ensure correct
installation
Dirty Water
Resistance
• Brass flow control stem — 50mm and 75mm
(2” and 3”) models
The 120-mesh, stainless steel filter screen is
positioned on the supply side of the water
stream. It is constantly flushed by the flow,
enabling the use of very dirty water without
clogging and valve closure failure.
