Description
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
-

- 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.
- Start and stop levels – can be easily adjusted to give water level differentials
