*This is a generic photo but a good representation of what you will receive in your kit.*

Note: Valve Spring 7270 is the current style spring for Suction Valves, non-Press Fit and early Press Fit Discharge valves. In November 2003 Quincy redesigned the 7271X series Discharge Valve to use a longer spring 7270-2. Kits listed in this catalog now contain both the 7270 and the New spring (7270-2) for Discharge Valves and the 7270 for Suction Valves.
