9644 VALVE ASSEMBLY KIT P430 P440 P450

SKU: 3171

SKU 3171 is the Giant Industries valve assembly kit #9644, listed for the P430, P440, and P450 triplex plunger pumps. A valve assembly kit replaces the inlet and discharge valve assemblies in the pump head - the small valves that meter water into each cylinder and out under pressure - and worn or leaking valves are a common cause of lost pressure, pulsation, and poor chemical draw. This is a genuine Giant OEM part; verify kit number 9644 against your pump's parts manual and series before ordering, since valve hardware differs between pump families and a near-fit will not seal correctly.
