The 700-250 bypass valve stem is a replacement component manufactured by Bedford for a wide range of spray equipment including numerous Airless Sprayer models (330, 340, 440 i, 440 XC, 440i, 550 XC, 640 i, 660 XC, 690 GXC, 840 i, 840 IX, 840i, 1100 XC, 1140 i, 1140 IX, 1200 GXC), Epic 447HPX/660ex/660HPX/1200 HPG, Performer 1140 ix, PowrLiner 2800/3100, ProMark II, RentSpray 450/Plus, and RentSpar 700. This stem is a critical component within the bypass valve assembly, which regulates system pressure by diverting excess fluid flow. The stem moves within the valve body, opening and closing against a seat to control bypass flow. A properly functioning stem, with its precisely machined surfaces, ensures smooth valve operation and accurate pressure regulation. A worn, damaged, or corroded stem can cause the valve to stick, leak, or fail to regulate pressure correctly, leading to pressure fluctuations or loss of system control. This aftermarket replacement stem is manufactured to meet or exceed original specifications for fit, material, and performance. Installation requires access to the valve assembly and careful cleaning. Regular inspection helps identify stem wear before it affects system performance.
| Pressure regulation | Controls bypass flow to regulate pressure |
|---|---|
| Valve actuation | Moves within valve to open/close flow path |
| Sealing interface | Works with seat to create seal when closed |
| Worn / scored surface | Stem surface damaged, causing leaks or sticking |
|---|---|
| Corrosion damage | Rust or pitting compromises stem |
| Bent stem | Stem deformation affects movement |
| Pressure fluctuation | Bypass valve not regulating properly |
