1" Topaz Differential Valve by Jobe | TPVD1*DLT

Optimize your water systems with Topaz Differential Valves from BARR Plastics, engineered for precise pressure control and reliable performance. These valves are ideal for maintaining consistent water flow and pressure in industrial settings. With advanced technology and robust construction, Topaz Differential Valves ensure superior fluid management and are essential for systems requiring precise water regulation. 

Topaz Differential valves are ideal for use in water tanks which are filled by a pressure system controlled water pump. The valve gives a level difference which is adjustable from 50mm up to 2.5m to minimise starting and stopping of the pumping system.

Applications:

Maintaining Water Levels in:

• Water Storage Tanks
• Water Cisterns
• Irrigation Applications

Principle of Operation

• The valve mounts at the top of the tank. It fits easily through a thin walled tank or screws into a threaded tank inlet.
• As the tank empties the weighted float travels down the cord until it hits the bottom stop. The valve then opens immediately to give a full flow.
• The valve now runs constantly and the weighted float rises until it hits the upper float stop. This lifts the arm and the valve shuts down.
• Observe the pressure that your pump runs at while the tank is filling. Set the pressure switch to turn the pump off at a pressure at least one bar above the running pressure.

Features

• High flow
• Start and stop levels can be easily adjusted to give water level differentials from 50mm to 2.5 m
• Keeps pump operation to a minimum.
• DetachTM Valve Seal Access System for quick access to valve seal (Patented)
• Ideal for all makes and models of tanks.
