HVAC & Data Center Safety Valves
HVAC systems and data center cooling loops operate 24/7 with zero tolerance for downtime. Aquatrol’s direct-acting and pilot-operated relief valves protect compressors, coolers, and recirculation pumps from thermal overpressure and pump deadhead while maintaining system efficiency. Pressure-rated for refrigerants, glycol coolants, and water-based media.
Why Aquatrol HVAC & Data Center Valves
Cooling system overpressure happens fast—a blocked condenser, stuck pump, or thermal transient can generate dangerous pressure in seconds. Our relief valves respond rapidly, protecting compressors and heat exchangers from rupture. Sizing accounts for system volume, pump displacement, and seasonal temperature swings to ensure reliable protection year-round.
Data centers demand uptime. Our valves are designed for reliability with minimal maintenance, straightforward field replacement, and stainless steel options for environments prone to corrosion. Refrigerant-compatible seals and materials ensure compatibility with common cooling media. Field-adjustable pressure settings allow commissioning without special tools.
HVAC systems experience wide temperature swings and thermal cycling stress. Aquatrol designs valves to handle these cycles without fatigue or seal degradation. Regular maintenance procedures are simple, and replacement is quick when required, minimizing downtime.
| Series | Pressure Range | Best For | Media |
|---|---|---|---|
| 55 | 20–500 PSIG | Chilled water systems | Water, glycol |
| 140 | 20–1,000 PSIG | Compressor discharge | Refrigerant, air |
| 141 | 20–800 PSIG | Cooler bypass relief | Refrigerant |
| 135 | 20–300 PSIG | Thermal expansion | Water, glycol coolant |
| 570 | 20–500 PSIG | Potable water systems | Water only |
