OVERVIEW

Protect Your Shop with ESAB Quality Safety Valves

Safety is the number one priority in any welding shop, and the integrity of your gas distribution system plays a huge role in that. The ESAB 11P64 Relief Valve is an essential upgrade or replacement part for any shop running a central gas system or manifold. Designed to automatically vent gas if pressure spikes, this valve ensures that your hoses, regulators, and welding machines are never subjected to pressures higher than they can handle. With a fixed setting of 75 PSI, it provides peace of mind that your low-pressure lines remain within safe operating limits.

Heavy-Duty Brass Design

Cheap components have no place in a professional welder's setup. ESAB has built this relief valve from high-quality brass, ensuring it stands up to the rigors of daily shop use. Brass is the industry standard for gas equipment due to its durability and spark resistance. Whether you are setting up a new argon drop for your TIG station or maintaining an oxygen line for cutting, this valve offers the reliability you expect from a top-tier brand like ESAB. The 3/4" NPT threads are precision-cut for a tight, leak-free seal when installed with the proper thread sealant.

Simple Installation, Maximum Protection

Installing the ESAB 11P64 is straightforward for anyone familiar with pipe fitting. It screws directly into standard 3/4" NPT ports found on many manifolds and receiver tanks. Once installed, it acts as a silent guardian for your equipment. If a regulator upstream fails and dumps high pressure into the line, this valve pops open to release the excess, preventing blown hoses or damaged flowmeters. It’s a small investment that protects thousands of dollars worth of welding gear and, more importantly, keeps you and your crew safe.

Why Choose This Valve?

  • Factory Calibrated: No guessing or adjusting; it's set to 75 PSI right out of the box.
  • Standard Fit: Fits common 3/4" pipe fittings found in most shops.
  • Automatic Reset: Closes itself once the pressure drops back to safe levels.

FAQ

This ESAB relief valve is factory set to open at 75 PSI.

The valve features a 3/4-inch NPT (National Pipe Taper) connection.

No, this is a fixed-setting relief valve designed to operate specifically at 75 PSI for safety compliance.

The valve body is constructed from durable brass, suitable for most industrial gas applications.

Yes, once the system pressure drops below the 75 PSI threshold, the valve is designed to close and reseat automatically.

While brass is generally compatible with oxygen, all components used in oxygen service must be cleaned specifically for oxygen use. Please verify the cleaning specification of the specific unit before installation.

It is typically installed on the low-pressure side of a regulator or on a gas manifold header to protect downstream equipment.

The internal spring mechanism will compress, opening the valve seal and allowing gas to vent to the atmosphere until pressure is reduced.
