Topaz Part fill Valve

Float operated valves for use in automatic filling of water troughs, tanks, cisterns etc. The valve is configured for above or below water mounting. The float operates a small pilot valve which in turn operates the main diaphragm valve. Topaz trough valves are a good choice where their high flow, compact, robust, non corrosive construction and high level of adaptability are needed.

Applications

Maintaining Water Levels in:

• Animal Drinking Troughs
• Water Storage Tanks
• Water Cisterns

• Air Conditioning Systems

• High Pressure Cleaning Systems
• Irrigation Applications

Features:

  • Ideal for use with all makes and models of rain water harvesting tanks
  • Compact
  • Constructed from non corroding materials
  • Valve can be locked in off position using the lock off switch
  • Up to 150mm differential obtainable (dependant on pressure)
  • Detach Valve Seal Access System for quick access to valve seal (Patented)

Principles of Operation

The Valve is installed through the side wall of a storage tank. It should be mounted above the over ow level of the tank to prevent back ow.

  • As the tank empties the weighted oat travels down the cord and sits on the bottom stop to activate the valve.
  • The valve will run until the weighted oat lifts clear of the bottom stop.
  • The float will then rise as rainwater lls the tank and falls as the tank water is used.
  • The Valve will only function at times when rain fall is insuf cient to maintain a water level in the tank above the bottom stop.

Pressure Range

1 Bar – 10 Bar (15psi-150 psi)

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 mininum.
    • DetachTM Valve Seal Access System for quick access to valve seal (Patented)
    • Ideal for all makes and models of tanks.
