A large nursery in Oregon uses several Cycle Stop Valve to control irrigation pumps. They have been using CSV's for several years and find that they give excellent control and dependable service. Recently a salesman talked them into trying a different brand of valve, claiming that a Cyclegard valve was "just like" a Cycle Stop Valve. A 6" Cyclegard valve by Danfoss Flomatic was installed. Problems immediately occurred from the speed control needle valve clogging with sand. Also the reaction time of the Cyclegard valve was too slow, and the pressure switch would bounce the pump off and on.
Several attempts were made to solve the problems to no avail. Since the nursery owner had several Cycle Stop Valves functioning perfectly, he ordered that the Cyclegard valve be removed and replaced with an original Cycle Stop Valve of the same size.
The Cycle Stop Valve does not have needle valves, as it does not need speed controls. The fast reaction time of the Cycle Stop Valve also keeps the pump from bouncing on and off when the flow rate in the field is changed. The following is a picture of the Cycle Stop Valve installation and the background shows happy trees receiving a dependable supply of water.
