Jobe Valves Vortex Differential Float Valve

Jobe Valves Vortex Differential Float Valve: Protect Your Pump, Minimize Cycling

If your tank is filled by a pressure-controlled water pump, the Vortex Differential Float Valve is purpose-built for you. Instead of triggering constant on-off cycling that wears down your pump, this valve creates a wide, adjustable gap between fill and shut-off levels—letting your pump run efficiently in longer, less frequent cycles.

Why a Differential Valve Matters

Standard float valves can cause a pressure-controlled pump to start and stop rapidly as the water level hovers near the shut-off point—a major source of premature pump wear. The Vortex Differential solves this with an adjustable level difference from 50mm up to 2.5 meters, so your pump runs a full cycle instead of chattering on and off.

How It Works

• Mount the valve at the top of the tank using a threaded tank inlet fitting.
• As the tank empties, the weighted float travels down the cord until it hits the bottom stop—the valve then opens immediately for full flow.
• The valve runs continuously while the weighted float rises, until it hits the upper float stop, lifting the arm and shutting the valve down.
• Set your pump's pressure switch to cut off at least one bar above its running pressure while the tank fills.

Key Features:

• High Flow: Fast, efficient tank filling.
• Adjustable Differential: Easily set water level differentials from 50mm to 2.5m.
• Minimizes Pump Cycling: Reduces wear and extends pump life.
• Easy Valve Access: The valve unscrews from the tail for simple servicing.
• Universal Fit: Works with all makes and models of tanks.

Common Applications: water storage tanks, water cisterns, and irrigation systems.

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, a different Detach tail can adapt your existing valve instead of requiring a full replacement.
