The Toro 1" in-line electric valve is designed for use in an automatic  
sprinkler system controlled by a 24 V a.c. sprinkler system timer.  
The valve features manual flow control adjustable down to zero flow  
and manual bleed control which enables the valve to be operated  
without the use of the timer. The 53799 valve is designed for  
poly pipe connections. This valve is generally installed below  
grade, grouped with other valves in a manifold arrangement and  
housed in a protective

of connection is required in most areas to prevent back-siphoning of contaminants through the  
sprinkler system into the potable water supply. The Toro 1" Pressure Vacuum Breaker (PVB), model  
number 53300, is specifically designed for this purpose. Before connecting your irrigation system to  
the potable water supply, consult with your local water utility department for information regarding  
backflow prevention requirements. Where local water pressure exceeds 70 psi, a pressure regulator  
should be used. (See Uniform Plumbing Code, Sec. 1007 [b].) It is advisable to use a regulator with  
any automatic valve to assure long life as well as uniform and controllable operation.  
Caution: Do not use the flow control to shut off the valve. Do not force the flow control  
screw past the end of normal adjustment travel. Damage can occur.
