Jobe 1/2" Topaz Differential Long Tail TPVD0050DLT

Topaz Differential valves in 1/2" Inlet are ideal for use in water tanks that are filled by a pressure system-controlled water pump. The 1/2" Inlet are high flow, start and stop levels can easily be adjusted and keeps pump operation to a minimum.

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.
