York 022-11704-000 Valve

The York 022-11704-000 is an OEM pressure relief valve engineered for critical overpressure protection in commercial HVAC and industrial refrigeration systems. This heavy-duty safety device is designed with a 3/8" MPT inlet and a 1/2" outlet, factory-set to trip at 400 PSIG. Built to withstand demanding chiller environments, the 022-11704-000 provides a reliable mechanical fail-safe to protect compressors and heat exchangers from catastrophic pressure spikes. As a genuine HVAC replacement part, it ensures precise calibration and seated integrity, maintaining system safety and refrigerant containment without the leak risks associated with lower-grade aftermarket alternatives. For technicians servicing York chillers or large-scale fluid handling systems, this valve is the high-performance standard for maintaining operational uptime and equipment longevity.

• Factory-Calibrated Precision: Set at 400 PSIG to ensure accurate lifting and reseating during overpressure events.
• OEM Compatibility: Exact replacement for York 022-11704-000, ensuring zero-clearance fitting and direct integration into existing refrigerant lines.
• Durable Brass Construction: High-grade materials resist corrosion and mechanical fatigue in high-vibration HVAC environments.
• Dual Connection Sizing: Features a standard 3/8 inch MPT by 1/2 inch configuration for versatile piping installation.

• What is the relief setting for this valve? This model is rated for a 400 PSIG relief threshold, specifically designed for high-pressure refrigerant loops.
• Can this be used with non-York systems? While engineered as a York replacement part, it is compatible with any industrial system requiring a 3/8" MPT relief valve with matching pressure specs.
• In what orientation should it be installed? Best practice dictates a vertical orientation to prevent debris accumulation on the valve seat, ensuring a 100% seal after discharge.
