Compact Livestock Float Valve

Product Name Compact Livestock Float Valve
Product Image Compact Livestock Float Valve
Product Overview The Compact Livestock Float Valve is a mechanically operated water-level control valve designed for automatic filling of livestock drinking troughs, water storage tanks and cisterns. Its narrow weighted float requires very little operating space, making the valve especially useful where conventional long-arm float valves are difficult to install.

The compact, corrosion-resistant construction supports reliable operation in commercial pig farms, cattle facilities, livestock buildings and agricultural water systems. Multiple mounting positions and adjustable float configuration provide flexibility for new farm construction, equipment replacement and water-system renovation projects.
Key Features
  • Compact weighted-float design for installations with restricted space.
  • Automatic mechanical operation requires no electricity or electronic controller.
  • Suitable for maintaining water levels in livestock troughs, tanks and cisterns.
  • Top, side or bottom mounting configurations provide flexible installation.
  • Fully adjustable float position supports different operating water levels.
  • Non-corrosive construction is suitable for humid livestock environments.
  • Integrated lock-off function allows the valve to be held closed during servicing.
  • Controlled closing action helps minimize water hammer in farm pipelines.
  • Multiple inlet sizes support different livestock water-supply layouts.
Structural Components
  • Valve Body: Compact corrosion-resistant housing for livestock and agricultural water applications.
  • Weighted Float: Narrow float designed to operate within a small installation envelope.
  • Inner Cartridge: Serviceable internal valve component controlling water flow.
  • Extension Arm: Connects the float to the valve mechanism and allows water-level adjustment.
  • Lock-Off Switch: Allows the water flow to be manually shut off for inspection or maintenance.
  • Inlet Tail and Backing Nut: Provide secure connection through a trough or tank wall.
  • Filter: Helps reduce debris entering the internal flow-control mechanism.
Working Principle When animals consume water and the trough level falls, the weighted float moves downward and opens the internal valve mechanism. Water enters automatically until the selected operating level is restored. As the float rises, the valve progressively closes and stops the incoming flow.

This simple mechanical principle maintains a stable water level without electrical power and helps reduce sudden hydraulic shock in the supply pipeline.

  • Adjust the extension arm and float position to establish the required operating water level.
  • Flush new water pipelines before commissioning to reduce debris entering the valve.
  • Check the filter, cartridge, float, arm and inlet connection periodically.
  • Use the lock-off function when servicing or cleaning the valve.
  • Remove sediment or mineral deposits if water flow becomes restricted.
  • Protect exposed water lines against freezing where required by local climate conditions.
Product FAQ

Q: What is the main advantage of a compact float valve?
A: Its narrow weighted float requires much less operating space than a conventional long-arm float, making it suitable for confined troughs, tanks and valve chambers.

Q: Is the valve suitable for commercial pig farms?
A: Yes. It can be used in suitable drinking troughs, header tanks, storage tanks and other livestock water systems requiring automatic level control.

Q: Does it require electricity?
A: No. The valve operates mechanically through the movement of the weighted float.

Q: Can the valve be mounted in different positions?
A: Yes. Top, side and bottom mounting configurations can be used according to the tank or trough structure.

Q: What inlet sizes are available?
A: Common configurations include 1/4", 1/2" and 3/4" connections, with BSP or NPT options depending on the selected model.

Q: Can the operating water level be adjusted?
A: Yes. The float position and extension-arm configuration can be adjusted to suit different installation requirements.

Q: Can project-specific configurations be supplied?
A: Yes. Connection type, mounting arrangement, packaging and related specifications can be supplied according to project requirements.
