Jobe Valves Topaz Industro Float Valve: The Hot Water & High-Temperature Float Valve If you're running hot water—a car wash hot water bay, a boiler room holding tank, a cooling tower, or any system where water temperature exceeds what a standard float valve can handle—the Topaz Industro is the one Jobe valve built for the job. Standard Topaz and Rojo valves are only rated to 140°F (60°C); using them on hotter water is a common cause of the sticking, dripping, and equipment-room flooding failures reported by car wash operators. The Topaz Industro is rated to a genuine 176°F (80°C), making it the correct choice whenever your application runs hot. Built for Heat, Built for Industry The Topaz Industro is a high-flow, float-operated valve engineered to maintain water levels in applications that call for extra mechanical strength and heat resistance—car wash hot water systems, cooling towers, storage tanks, high-pressure cleaning systems, and light industrial, air conditioning, or irrigation installations. The key difference from the standard Topaz is the materials: the Industro is built to withstand higher temperatures, making it the right choice when your application runs hotter than a standard valve can handle. It's configured for above or below water mounting, with the float operating a small pilot valve that in turn drives the main diaphragm. Temperature Rating Comparison Standard Topaz: Max operating temperature 140°F (60°C) — not rated for hot water applications. Topaz Industro: Max operating temperature 176°F (80°C) — the correct choice for car wash hot water bays, boiler rooms, and other high-temperature systems. Topaz Differential: Standard units are not rated for hot water; high-temperature models are available by special order from Jobe. Using the wrong valve on hot water doesn't just risk premature failure—it's the most common cause of a valve sticking open and flooding an equipment room. If your system runs hot, the Industro is the valve to install. Key Features: Float-Operated Mechanism: As water rises, the float ascends and triggers the valve to close; as it drops, the valve reopens to refill. Adjustable Water Level: Float adjusts easily, with no tools required. Durability and Corrosion Resistance: Built to hold up across a wide range of environments. High Flow Rate: Delivers up to 55 GPM (3/4" inlet) or 90 GPM (1" inlet), fast enough for demanding commercial tanks. Heat Resistance: Constructed from heat-resistant materials, rated to a maximum water temperature of 176°F (80°C). Pressure Rating: 5–100 PSI (0.3–7 Bar). Common Applications: Car wash and truck wash hot water systems Water storage tanks Water cisterns Air conditioning systems High-pressure cleaning systems Irrigation applications Long Tail vs. Short Tail The key difference is the amount of thread available to attach to your plumbing—short tail valves do not include a backing nut and seal washer. Selecting the Right Inlet Size Match your valve's inlet size to your supply plumbing—your flow rate will always be limited by the smallest pipe in the system. If you upgrade your plumbing later, you can purchase a different Industro Detach tail rather than replacing the whole valve. See our Industro Detach Short Tail and Industro Detach Long Tail.
