Description
1-Inch Stainless Steel Anti-Siphon Solenoid Valve for Fuel Systems & Liquid Cooling Infrastructure
The Morrison Bros. 710SS is a normally closed, hung-piston solenoid valve with a 304 stainless steel body and PTFE seals, sized at 1″ NPT for mid-range flow applications. It installs on the dispensing side of a fuel or fluid pipeline, remaining closed until an electronic signal (from a dispenser, pump controller, or BMS) commands it open. The 1″ size carries a CV of 12 and handles operating pressures up to 105 PSI, making it a practical fit for single-rack or small-cluster coolant distribution unit (CDU) supply and return lines where moderate flow rates and a compact footprint are priorities. Zero pressure differential operation means the valve opens reliably even under low-pressure start-up conditions common in server rack manifolds.
The 304 SS body and PTFE seal combination resists galvanic corrosion and ion contamination in deionized water loops, glycol-based coolants, and dielectric fluids used in direct-to-chip and immersion cooling systems. The integral thermal relief feature protects closed loop segments from pressure spikes caused by thermal expansion under high server loads. The Class H coil operates at 120V AC standard, with the explosion-proof NEMA 3/4X/7/9 enclosure covering hazardous location requirements (relevant for two-phase immersion cooling environments with low-flashpoint fluid volatility).
