Description
Heavy-Duty Direct Lift Valves for Petroleum & Gravity-Feed Service
The Rancho Factory 878X Series delivers robust high-flow fluid control in environments where traditional diaphragm valves fail to perform. These heavy-duty, normally closed solenoid valves have a direct-lift piston design that requires zero differential pressure to operate, making them ideal for anti-siphon control on above-ground storage tanks and low-pressure gravity-fed systems. Made from industrial-strength cast bronze with high-performance FKM (Viton) seats, the 878X is engineered to handle demanding petroleum derivatives including gasoline, diesel, jet fuel, and bio-fuels at fluid temperatures up to 300°F. For maximum safety and reliability in hazardous industrial applications, these valves feature an explosion-proof housing that meets UL, CSA, and ATEX directives.
Key performance features include:
- Integrated Pressure Relief: Helps absorb thermal expansion within the fuel supply or transfer lines.
- Superior Flow Capacity: The piston assembly provides a significantly higher Cv (from 7 to 91) compared to standard diaphragm alternatives.
- Suitable for Data Center Liquid Cooling:
- Extreme Environment Ready: Rated for a minimum ambient temperature of -42°F and capable of handling fluid temperatures up to 300°F, accommodating the high-heat demands of modern high-density server racks.
- Versatile Sizing: Available in female NPT threaded connections from 3/4″ up to 3″ to match your specific piping requirements.
Zero differential operation allows for operation at zero PSI to suit low-pressure cooling loops. It also features built-in pressure relief to manage thermal expansion and high flow rates with a piston-style design.
