Henry Technologies 7771 Valve

The Henry Technologies 7771 is a high-pressure forged steel shut-off valve designed for critical fluid control in industrial refrigeration and HVAC systems. Featuring a 1/4" MPT x 1/4" FPT configuration, this valve is engineered to handle high-pressure refrigerants and liquid lines where leak prevention is a non-negotiable requirement. The forged steel construction provides superior structural integrity compared to cast alternatives, ensuring a high pressure rating that meets the demands of heavy-duty ammonia or CO2 applications. This compact needle valve allows for precise isolation or throttling, making it an essential component for gauge mounting or oil return lines. Its robust stem design prevents accidental back-out under pressure, satisfying safety protocols for HVACR shut-off solutions. For technicians requiring a reliable manual shut-off valve with standard 1/4 inch NPT fittings, the 7771 offers a durable, low-maintenance solution that stands up to vibration and thermal cycling without compromising the seal.

• Forged Steel Durability: Engineered for resilience in high-pressure environments, providing a significantly longer service life than standard brass valves.
• Precision Fluid Control: The compact design allows for fine-tuned throttling, ideal for refrigerant isolation and system diagnostic ports.
• Leak-Proof Connection: Precision-machined 1/4" MPT and 1/4" FPT threads ensure a secure, airtight fit into existing manifolds and piping.
• Industrial Compatibility: Suitable for use with a wide range of refrigerants, including those used in low-temperature and high-pressure industrial systems.

Is the Henry 7771 compatible with ammonia systems?
Yes, the forged steel construction and internal seal materials are specifically chosen for compatibility with ammonia (R-717) and other common industrial refrigerants.

What is the primary application for this shut-off valve?
This valve is most frequently used as a gauge isolation valve or on oil pots and liquid lines where a small-bore, high-pressure manual shut-off is required.

Can this valve be used for throttling?
While primarily a shut-off valve, the needle-style seat design allows for moderate throttling capabilities for precision flow management in small-diameter lines.
