Titan 107-058 Outlet Valve Seat
Powr part 107-058 is an outlet valve seat – a precision sealing surface that works with the outlet valve ball to control fluid discharge on compatible PowrBeast, PowrLiner, and PowrTwin pumps. This seat provides a leak‑tight seal when the valve is closed, ensuring consistent pressure and preventing backflow. Replacing a worn, pitted, or cracked outlet valve seat restores proper sealing, eliminates pressure loss, and ensures reliable pump performance.

Outlet Valve Seat for PowrBeast, PowrLiner & PowrTwin Pumps
The Powr 107-058 Outlet Valve Seat is a precision‑machined component that forms the sealing surface for the outlet valve ball in the pump manifold of many PowrBeast, PowrLiner, and PowrTwin sprayers. Together with the valve ball, it creates a one‑way check valve that allows pressurized fluid to exit the pump while preventing backflow during the intake stroke. The seat's smooth, hard surface is critical for maintaining a leak‑tight seal and consistent pressure.
Over time, the outlet valve seat can become worn, pitted, or cracked due to chemical attack, cavitation, or debris in the fluid. A damaged seat allows fluid to bypass the ball, resulting in pressure loss, pulsation, reduced flow, and inefficient operation. Replacing the outlet valve seat restores the sealing integrity, eliminates bypass, and ensures the pump delivers consistent pressure and flow.
What it does and when to replace it
| Sealing surface | Provides a smooth, durable surface for the valve ball to seal against, preventing backflow |
|---|---|
| Pressure maintenance | Ensures rated pressure is sustained by preventing fluid bypass past the ball |
| Flow direction control | Works with the ball to allow flow in one direction only (check valve function) |
| Visible wear / pitting | Grooves, pits, or erosion on the sealing surface |
|---|---|
| Cracks or breakage | Any cracking compromises the seat's ability to seal |
| During pump overhaul | Always replace when rebuilding the pump to ensure optimal performance |
| Persistent pressure loss | If pressure remains low after replacing seals, the seat may be worn |
