19215 - ESAB 19215 Regulator Seat Assembly Slo-Open

Restore Regulator Safety with the ESAB 19215 Seat Slo-Open Valve

The ESAB 19215 Seat Slo-Open Valve is a critical replacement component designed for the maintenance and repair of industrial gas regulators, specifically those manufactured under the ESAB, Purox, and Oxweld brands. This seat assembly is an integral part of the "Slo-Open" valve mechanism, a vital safety feature found in high-quality oxygen regulators.

In high-pressure oxygen systems, the rapid introduction of gas into a low-pressure chamber can cause adiabatic compression, generating intense heat that poses a fire risk. The Slo-Open valve is engineered to restrict this initial surge, allowing pressure to build gradually and safely. Over time, the seating material within this valve can wear, degrade, or become contaminated, compromising both the sealing capability and the safety function of the regulator. Replacing the seat with a genuine ESAB 19215 ensures that your equipment continues to operate within safe parameters.

This assembly features precision-machined brass components and high-grade elastomeric seating materials compatible with oxygen service. It is designed to provide a leak-tight seal when the regulator is closed and a controlled flow profile when opened. Professional installation is recommended to ensure the regulator is calibrated and assembled correctly according to manufacturer specifications.

Key Applications

• Repairing leaking Purox or Oxweld oxygen regulators.
• Routine maintenance of heavy-duty industrial gas equipment.
• Restoring the safety functionality of the slow-opening mechanism.
