Marathon Valve’s Guardian® reset relief valves are the only patented valves available to the industry with an internal design engineered to handle not only the high operating pressures of today’s deeper drilling but also enhancing the service life of the valves against the corrosion and erosion factors associated with drilling muds.

Every valve is hydrostatically tested, calibrated, and certified in our Houston facility with full material traceability and material tests on all pressure containing components.

We invite you to contact us about the Guardian® valve line or if you need assistance troubleshooting your current reset relief valve, call or email us directly. Marathon Valve is committed to be the preferred supplier for your mud pump packages and reset relief valve upgrades.
