Henry Technologies 5600-250 Valve

The Henry Technologies 5600-250 Valve is a heavy-duty pressure relief valve engineered specifically for technical professionals managing commercial refrigeration systems and industrial HVACR infrastructure. This angle type relief valve features a ductile iron body with a protective lacquer finish, ensuring durability and corrosion resistance in demanding mechanical environments. Built to meet rigorous safety standards, the valve is ASME UV stamped and National Board certified, providing reliable overpressure protection for liquid receivers, suction accumulators, and other pressure vessels.

This unit is configured with a 1/2" FPT inlet and a 3/4" FPT outlet, tailored for high-flow discharge requirements. With a precise 250 PSI pressure setting, it is compatible with a wide range of refrigerants, including ammonia (R-717), HFCs, and HCFCs. The internal mechanism utilizes stainless steel seat inserts and a chemically-inert PTFE (Teflon) seal to maintain zero-leak seat tightness up to 90% of the set pressure. For veteran contractors, the Henry 5600 series represents a standard in HVAC safety valves, offering easy integration into discharge piping while preventing equipment damage from system malfunctions or external heat loads.

• Enhanced Durability: Robust ductile iron construction with a protective coating for longevity in harsh environments.
• Wide Compatibility: Suitable for ammonia refrigeration and standard synthetic refrigerants.
• Code Compliance: ASME Section VIII Division 1 compliant with unique serialization for site tagging and documentation.
• Precision Performance: Stainless steel internals and PTFE seating ensure reliable resets and minimal blowdown.

Is the Henry 5600-250 suitable for liquid relief?
No, this pressure relief valve is certified for gas and vapor service only. It must be installed in the vapor space of the vessel, typically at the top, to function correctly.

Can I field-adjust the pressure setting on this valve?
No. These valves are factory set and sealed. Breaking the seal to adjust the pressure voids the ASME certification and compromises system safety.

What is the recommended replacement interval for this relief valve?
Industry standards and the manufacturer recommend replacing refrigeration relief valves every five years or immediately after any discharge event to ensure the 250 PSI set point remains accurate.
