Titan 317-925 Foot Valve
Hydra part 317-925 is a foot valve designed to maintain pump prime and prevent material backflow on compatible Hydra M 2000, Hydra M 4000, and Hydra Pro Super sprayers. This one-way check valve installs at the end of the suction tube, allowing material to enter the pump while preventing it from draining back into the container when the pump stops. Replacing a worn, leaking, or damaged foot valve ensures reliable priming and prevents costly downtime.

Foot Valve for Hydra M 2000, M 4000 & Hydra Pro Super Sprayers
The Hydra 317-925 Foot Valve is a one-way check valve installed at the end of the suction tube on compatible Hydra sprayer models. Its primary function is to maintain pump prime by allowing material to flow into the pump while preventing it from draining back into the supply container when the pump stops.
The foot valve is critical for reliable pump operation. During the suction stroke, the valve opens to allow material to enter the pump. When the pump stops or during the pressure stroke, the valve closes tightly, trapping material in the suction line and keeping the pump primed and ready for immediate restart. A properly functioning foot valve eliminates the need for repeated priming, saving time and reducing material waste.
Over time, foot valves can become clogged with debris, worn at the sealing surfaces, or weakened in their spring action. A worn or leaking foot valve allows material to drain back, causing loss of prime and requiring frequent re-priming. Replacing a worn or damaged foot valve restores reliable priming, ensures consistent material delivery, and prevents downtime.
What it does and when to replace it
| One-way flow | Allows material into suction line, prevents backflow |
|---|---|
| Prime retention | Maintains pump prime when not operating |
| Check valve function | Seals tightly to prevent material drain-back |
| Loss of prime | Pump requires frequent re-priming |
|---|---|
| Material drain-back | Fluid drains from suction line when pump stops |
| Clogging | Valve is blocked, restricting flow |
| Visible wear | Valve seat or seal is damaged |
