Safety should always be one of the highest priorities when building or operating a steam distillation system. The Philbilly Moonshine Adjustable Inline Pressure Relief Valve provides a simple way to add an adjustable pressure relief device directly into your 2-inch or 1.5-inch tri-clamp plumbing.

Designed to install between two standard 2-inch sanitary tri-clamp ferrules, this valve can be incorporated almost anywhere in your steam line where pressure protection is needed.

Unlike fixed-pressure relief valves, this model features an adjustable pressure range from approximately 0 to 100 PSI, allowing you to set the opening pressure for your specific application. While the valve is capable of higher settings, most steam distillation systems are typically operated with much lower relief settings. Depending on your equipment, many builders choose settings in the 10–20 PSI range. Always confirm the actual relief pressure with a properly calibrated pressure gauge and ensure your entire system is designed and rated for the intended operating pressure.

• Durable construction for long service life

Great For

• Steam distillation systems
• Steam generators
• Botanical extraction equipment
• Mash cookers
• Experimental distillation projects
• Custom stainless process systems

Why Use an Inline Pressure Relief Valve?

Steam can create pressure quickly inside a closed system. An appropriately selected and properly adjusted pressure relief valve can help prevent excessive pressure from building by venting when the preset pressure is reached.

Adding an inline relief valve gives builders another option when designing custom steam systems and provides flexibility in choosing the installation location within a 2-inch or 1.5-inch tri-clamp assembly.

Installation

This valve installs between any two standard 2-inch or 1.5-inch tri-clamp ferrules using a gasket and tri-clamps (sold separately unless otherwise noted).

Once installed, adjust the spring tension to your desired relief pressure and verify the opening pressure using an accurate pressure gauge before operating your equipment.

Important Safety Information

This product should only be installed on equipment that is properly designed and pressure-rated for its intended use. Never exceed the pressure rating of any component in your system. Always verify the relief pressure before use, inspect the valve regularly, and follow safe operating practices whenever working with steam or pressurized equipment.

Whether you’re building your first steam distillation setup or upgrading an existing system, this 2-inch or 1.5-inch Tri-Clamp Adjustable Inline Pressure Relief Valve offers a clean, professional solution for adding adjustable pressure protection to your equipment.
