Titan 138-340 Foot Valve Ball
OEM Titan Flow Control Component
Titan 138-340 Foot Valve Ball is an OEM carbide intake ball used in the foot valve assembly of compatible PowrTwin, PowrLiner, PowrBeast, and PowrCoat sprayer models, controlling material flow into the pump and preventing loss of prime.
Compatibility Overview
Seats against the foot valve to prevent material from draining back out of the pump during the pressure stroke. A worn, pitted, or stuck ball causes loss of prime, erratic delivery, and the pump to deliver on only one stroke. OEM replacement restores reliable one-way intake flow.

Titan 138-340 Foot Valve Ball for Inlet Valve Service
Titan 138-340 is an OEM carbide intake ball used in the foot valve assembly of a wide range of Titan airless sprayers and heavy material pumps. Documented in the PowrLiner PL4955 service manual as the foot valve ball that sits on the foot valve seat, this precision ball controls material flow into the pump during the suction stroke and must seal properly against the foot valve seat to prevent material from draining back during the pressure stroke. Bedford Precision cross-references the 138-340 as the "Intake Ball" replacement for the Titan Atlas 30:1 platform. Over time, foot valve balls can become worn, pitted, or stuck to the seat due to debris or material buildup. A ball that fails to seat properly causes the pump to lose prime, deliver material on only one stroke, or stop pumping entirely. This replacement restores reliable one-way intake flow and consistent pump performance.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan carbide intake ball for the foot valve assembly, controlling material flow into the pump and preventing backflow during the pressure stroke. |
| Function | Lifts off the foot valve seat during the suction stroke to allow material into the pump, then reseats during the pressure stroke to prevent material from draining back. |
| System Location | Foot valve assembly, inlet side of the fluid pump. Referenced in PowrLiner PL4955 service manuals as the foot valve ball. |
| Documented Compatible Models | PowrTwin 3500, 3500-DC, 4500, 4900 Plus, 4900GH, 4900XLT; PowrLiner 4000, 4950, 4955, 5000, 6900XLT; PowrBeast 4700T/4700; PowrCoat 730, 745, 940, 960, 975; Commander 140-556, 742-555/742-557; Admiral 850-555/850-557; PowrTex Heavy Material Sprayer. Verify your exact model and revision against the service manual before ordering. |
| OEM Part Number | 138-340 Foot Valve Ball (Intake Ball). |
| Common Problems Solved | Loss of prime, pump delivering on upstroke only or downstroke only, material not being drawn from container, and pump failing to build pressure. |
| Replacement Indicators | Visible wear, pitting, or flat spots on the ball; ball stuck to the seat; pump loses prime; or pump delivers on only one stroke. |
| Related Parts Commonly Serviced Together | Foot valve seat, foot valve housing, PTFE O-ring, and seat O-ring. Inspect the seat for damage when replacing the ball. |
| Installation Notes | Remove the foot valve housing, clean any debris from the housing and seat, and place the new ball onto the foot valve seat. Test the foot valve by filling with water; if the ball fails to seal the seat, replace the ball. |
The 138-340 Foot Valve Ball is a critical check valve component in the pump inlet. If the sprayer loses prime, delivers material on only one stroke, or fails to draw from the container, inspect the foot valve ball and seat for debris or wear. Always clean the foot valve housing thoroughly before installing a new ball, and test the seal with water before reassembling the pump. Verify model compatibility against your Titan service manual, as foot valve configurations vary across sprayer platforms.
