Cycle Stop Valves, Inc. manufactures constant pressure pump control valves and the Cycle Sensor pump monitors. Our shop is located in Lubbock, TX. We started this venture in the back of our pump and drilling business in 1993. As with many new products, necessity is the mother of invention. Our frustration with variable speed drives is what led us to a simpler, more dependable, less expensive solution using valves. We installed our last VFD in 1992. 

Our customer service is second to none and we always do our best to help out our customers even if it is not a "valve" problem. Our combined experience includes licensed drilling and pump installers as well as a qualified irrigation specialist and a Cad designer on staff. We have accumulated five patents over the years. Our staff at Cycle Stop Valves can boast a combined total of well over 100 years experience in the pump and drilling industry, which makes our customer support second to none. Cycle Stop Valves were designed in the field, not engineered in a lab. We used our own experiences to make "constant pressure" systems work for real people in real world applications.
