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.
Features & Benefi ts

High-Grade Construction
Made of durable materials to resist wear.
Globe and Angle Confi gurations
Easy to use in any application.
Fabric-Reinforced Rubber Diaphragm
Provides long-term tear and stretch tolerance.
Water Flow Control Handle
Adjusts the fl ow of each zone on a system.
Robust ABS Material
Ensures the valve will resist heavy pressure and high fl ows without damage.
Effl uent Options Available
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.
