The piston valve is the check at the bottom of the piston rod, and it is what lets the pump build pressure on the down stroke.\u003c\/p\u003e\n\u003cp\u003eA worn piston valve shows up as a pump that will not hold on one stroke. If the pump holds going down but drops going up, or the other way round, the fault is in one of the two valves rather than in the packings. Traffic paint is abrasive and the piston valve wears alongside the intake seat, so it is worth having both on the shelf ahead of a marking season.\u003c\/p\u003e\n\u003cp\u003eSupplied as Graco's complete piston valve kit.
