INSTALLATION INFORMATION

Series 725S Diverter Valves are available with three different types of 
pipe preparation, for use with three types of Victaulic products.

• 

Cut grooved pipe ends, for use with Victaulic EndSeal™ couplings

• 

Double grooved pipe ends, for use with Victaulic Style 808 couplings

• 

Pipe prepared with rings, for use with Victaulic Style 809 couplings

Series 725S Diverter Valves can be installed in horizontal or vertical 
positions, or in any intermediate position that allows for access to the 
actuator or gear operator.
Series 725S Diverter Valves and connecting  piping must be supported 
to prevent the joints from being  subjected to bending loads, shear loads, 
or any other external loads.

• 

Using both lifting lugs, support the valve to ensure balanced 
loading. In addition, a cradle or cribbing can be used to provide 
increased support.

• 

WELDING TO SERIES 725S DIVERTER VALVES AND 
COUPLINGS IS NOT PERMITTED.

ACTUATOR SETUP

Always refer to the actuator manufacturer’s manual for complete setup 
and operating requirements.
Actuators are designed to operate within the parameters specified in 
the table below. Additional information will be required to determine 
appropriate specifications for your system.
