252 Series Valves
Valves
Toro® 252 Series valves are built tough and ready to withstand the harshest conditions in any commercial application.
With several confi gurations to choose from, 252 Series valves
are available in electric or hydraulic, 1”, 1.5” and 2” globe/
angle models with fl ow control. Offering the same glass-fi lled
cap and body construction as the 250/260 Series, these valves
are also rated up to 150 PSI. Each valve diaphragm is a single
piece and made with fabric- reinforced rubber for long-term
tear and stretch tolerance. All models are female inlet/outlet
NPT and their durable plastic construction makes them an
economical option for commercial applications.

252 Series Valves
Globe and Angle
In One Valve
The all-in-one globe
and angle configuration of the 252
Series valves allows
flexibility in design
and installation.
Angle installations
allow for less friction loss across the
piping system while
globe configurations are standard
in many irrigation
systems.

External Bleed
The external bleed allows perfect
manual operation of the valve
without electrically charging the
solenoid. With the ability of
users to bleed the valve to atmosphere, pressure is relieved and
the valve can effectively open
and close. System flushing can
also be accomplished using the
external bleed with debris and
other material being flushed out
of the port.

Note: For optimum performance when designing a system, be sure to calculate total friction loss to
ensure sufficient downstream pressure.
For optimum regulation performance, size regulating valves toward the higher flow ranges. Flow rates are
recommended not to exceed 5 psi (0,3 bar) loss.
