Heavy-Duty Metal Trough Float Valve

The Heavy-Duty Metal Trough Float Valve automatically maintains a preset water level in livestock drinking troughs, tanks and compatible watering reservoirs. As animals consume water, the internal float mechanism opens the inlet and automatically refills the trough.

Its durable aluminum housing protects the operating components from livestock contact and daily farm use. The compact mechanical design requires no electricity, making it suitable for commercial pig farms, livestock buildings and centralized trough watering systems.

• Automatic Water-Level Control: Refills the trough automatically as the water level drops.
• Heavy-Duty Aluminum Housing: Provides stronger protection than common plastic-bodied float valves.
• High Flow Capacity: Reference configuration delivers up to approximately 245 gallons per hour.
• Mechanical Operation: Requires no electricity, controller or external sensor.
• Protected Float Mechanism: The operating float is positioned beneath the housing and protected from direct animal contact.
• Standard Water Connection: Compatible with a standard 3/4-inch garden-hose connection.
• Compact Installation: Mounts directly on the rim of compatible troughs, tanks, barrels and pans.
• Optional Expansion Brackets: Extended mounting hardware is available for wider or thicker trough rims.

• Aluminum Protective Housing: Shields the valve mechanism from livestock and physical impact.
• Internal Float: Detects changes in trough water level.
• Valve Mechanism: Opens and closes the incoming water supply according to float position.
• Nylon Orifice: Controls water entry through the valve.
• Water Inlet: Accepts a standard 3/4-inch hose connection.
• Mounting Brackets: Secure the complete valve assembly to the trough or tank rim.

The float is positioned at the water surface inside the trough. When pigs or other livestock consume water, the water level falls and the float moves downward, opening the inlet valve.

Fresh water then enters the trough until the rising water lifts the float back to the shutoff position. The valve closes automatically when the desired water level is restored, providing continuous mechanical level control without electrical power.

Installation:

• Mount the valve securely on a compatible trough or tank rim.
• Position the internal float at the desired operating water level.
• Connect the water supply to the 3/4-inch inlet using a compatible hose or adapter.
• For thick or wide trough rims, select a suitable expansion-bracket configuration.
• Flush the water line before placing the valve into service.
• Open the supply gradually and confirm that the valve shuts off completely at the required water level.

Maintenance:

• Inspect the float and valve movement regularly.
• Remove sediment, scale and feed contamination from the valve area.
• Check the water connection and mounting brackets for looseness or leakage.
• Use a prefilter where the water supply contains sediment.
• Replace worn valve or float components when automatic shutoff becomes unreliable.

Q1: How does the trough float valve work?

The internal float drops when the water level falls, opening the valve. As the trough refills, the float rises and automatically shuts off the incoming water.

Q2: Does the valve require electricity?

No. It operates entirely through the mechanical movement of the float and water pressure.

Q3: What is the reference flow capacity?

The reference metal valve can deliver up to approximately 245 gallons per hour under suitable supply conditions.

Q4: What water pressure can it operate with?

The reference operating range is approximately 20-50 psi.

Q5: What type of water connection is required?

The reference configuration accepts a standard 3/4-inch garden hose connection.

Q6: Can it fit thick trough rims?

Yes. Optional expansion-bracket versions are available for compatible thick or wide trough rims.

Q7: Is an anti-siphon version available?

Yes. Anti-siphon configurations can be selected where back-siphoning protection is required by the project or local installation standard.

Q8: What information is required for a quotation?

Please provide the required quantity, trough type, rim dimensions, water pressure, water connection, required flow capacity and project location.
