Globe and Angle
In One Valve
The all-in-one globe
and angle con-
figuration of the 252
Series valves allows
flexibility in design
and installation.
Angle installations
allow for less fric-
tion loss across the
piping system while
globe configura-
tions 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 atmo-
sphere, 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: DC Latching Solenoid not available.

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.
