Titan 800-910 Bypass Valve Seat
OEM Titan Fluid Section Component
Titan 800-910 Bypass Valve Seat is a genuine OEM precision sealing surface for the bypass valve assembly in compatible Titan airless sprayers and line stripers, working with the bypass valve stem to regulate pressure recirculation when the gun is triggered off.
Compatibility Overview
Replace if the pump loses pressure when triggered, surges or pulses, or if the seat shows visible pitting, scoring, or grooves.

Titan 800-910 Bypass Valve Seat for Pump Pressure Regulation
Titan 800-910 is a genuine OEM bypass valve seat engineered to provide a precision sealing surface within the fluid section of compatible Titan airless sprayers and line stripers. It works together with the bypass valve stem to direct paint flow back to the inlet when the spray gun trigger is released, preventing pressure buildup and recirculating material. When the gun is triggered, the valve closes to send full pressure to the tip. The official Titan 1200GXC service manual instructs technicians to inspect the ball on the end of the bypass valve stem and the seat located in the bypass housing, cleaning or replacing if damaged. eReplacementParts confirms compatibility with a wide range of models including the 740I, 840I, 1140I, 1140IX, PowrLiner 2800, ProMark II, RentSpray 700, LineCrew 750/1600, and GPX series. Over time, the seat can become pitted, scratched, or worn from abrasives in paint or normal cycling, causing bypass valve leakage and pressure loss.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | Genuine Titan OEM bypass valve seat for compatible airless sprayers and line stripers. Provides a precision sealing surface within the fluid section. |
| Function | Seals the bypass port to prevent paint from recirculating when the gun is triggered. Helps maintain steady pressure during spraying. Allows paint to flow back to the tank when the gun is closed, preventing dead-heading. |
| Compatible Titan Models | 740I, 840I, 1140I, 1140IX; Performer 1140IX; PowrLiner 2800; ProMark II; RentSpray 700; LineCrew 750, 1600; GPX80, GPX1250, GPX1600; LCX130. |
| OEM Part Number | 800-910 Bypass Valve Seat. |
| Replacement Indicators | Pressure loss or surging when gun is triggered; pump won't build pressure to cutoff; excessive tip wear or spitting; visible pitting, scoring, or grooves on the seat surface. |
| Related Parts Commonly Serviced Together | Bypass valve stem/piston, valve spring, O-rings/seals for the bypass assembly. |
| Common Problems Solved | Restores positive sealing at the bypass port, eliminates pressure loss and surging, and ensures consistent spray performance. |
| Why Genuine OEM | Exact dimensions and material specifications ensure proper fit and reliable sealing. A low quality or worn seat may fail to seal, causing continued pressure issues and erratic operation. |
When replacing the bypass valve seat, always inspect the bypass valve stem and spring for wear. Use a seat removal tool to avoid damaging the pump housing. Lubricate new O-rings with pump oil before assembly. Follow the service procedure in your sprayer's manual, which typically involves removing the bypass valve handle and housing to access the seat. Always relieve system pressure and disconnect power before servicing.
