Jobe Valves Topaz Compact Float Valve

Jobe Valves Topaz Compact Float Valve: High Performance, Small Footprint

Not every tank has room for a full-size valve. The Topaz Compact is built for exactly that situation—a float-operated valve for automatic filling of troughs, tanks, and cisterns where space above the water line is limited. Configured for above-water mounting only, its compact weighted float operates a small pilot valve which in turn drives the main diaphragm, giving you positive on/off control in a smaller footprint—an especially good fit when working with pump-supplied water in a tight compartment.

Key Features:

• Compact Weighted Float: Delivers the same reliable shut-off in a smaller installation envelope.
• High Flow: Compact size doesn't mean compact performance.
• Corrosion-Resistant Construction: Robust materials built for continuous outdoor and industrial use.
• Anti-Water Hammer Design: Shuts down slowly to protect your plumbing from pressure spikes.
• Wide Pressure Range: Rated 0.3–10 Bar (5–150 PSI).
• Tool-Free Adjustment: Float position adjusts easily with no tools required.
• Lock-Off Switch: Manually locks the valve off for maintenance.
• FrostPro Compatible: Has a port to connect the FrostPro anti-freeze device.
• Detach™ Valve Seal Access System (Patented): Quick, tool-free access to the valve seal for servicing.

Common Applications:

• Animal drinking troughs
• 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. See our Detach Short Tail and Detach Long Tail pages for details.

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.
