Compact High-Flow Float Valve

• High-flow design for rapid replenishment of livestock drinking troughs and water tanks.
• Compact weighted float requires less operating space than conventional long-arm float valves.
• Positive on/off operation provides reliable automatic water-level control.
• Pilot-operated diaphragm mechanism supports high flow from a compact valve body.
• Suitable for pressure-fed and pump-supplied farm water systems.
• Slow valve closing helps minimize hydraulic shock and water hammer in supply pipelines.
• Corrosion-resistant construction is suitable for humid livestock housing environments.
• Float position can be adjusted without special tools.
• Integrated shut-off lock allows the valve to be held in the closed position during maintenance.
• Service-access design simplifies inspection and replacement of the valve seal.

• Valve Body: Glass-filled nylon construction combining mechanical strength with corrosion resistance.
• Compact Weighted Float: HDPE float designed to operate efficiently in confined spaces.
• Pilot Valve: Small control valve actuated by float movement.
• Main Diaphragm: EPDM diaphragm controlling the primary water flow.
• Actuator Assembly: Mechanical linkage transferring float movement to the pilot-control system.
• Flow Filter: Helps protect the pilot passage against debris from the water supply.
• Stainless Steel Hardware: Springs, bolts, nuts, pins and screws manufactured from corrosion-resistant stainless steel.
• Detach Base: Service-oriented connection providing convenient access to the valve seal.

• Commercial pig farm drinking-water systems
• Cattle and dairy drinking troughs
• Sheep and goat watering systems
• Livestock water storage tanks
• Automatic trough-filling systems
• Water tanks and cisterns with restricted valve space
• Pump-supplied agricultural water systems
• Livestock holding areas and outdoor watering stations
• Steel structure livestock buildings and complete farm construction projects
• Irrigation and agricultural water-management applications

• Inlet Size: Selected according to project water demand.
• Thread Standard: BSP or NPT configurations available upon request.
• Tail Configuration: Short-tail or long-tail arrangements available according to installation requirements.
• Connection Configuration: Customizable according to trough and pipeline design.
• Flow Configuration: Selected according to farm water pressure and peak livestock drinking demand.
• Packaging and Labeling: Available upon request for distributors, dealers and project procurement.
• Project Configuration: Designed according to local climate and farm conditions.

• Install the valve above the normal water level with adequate clearance for unrestricted float movement.
• Select the correct inlet size according to supply pressure, trough capacity and required refill rate.
• For back-siphon protection, installation should comply with applicable local plumbing requirements and overflow-clearance regulations.
• Flush new pipelines before commissioning to prevent installation debris from entering the pilot valve and filter.
• Adjust the float position to achieve the required operating water level; routine adjustment can be completed without special tools.
• Use the integrated shut-off function when servicing the valve where applicable.
• Inspect the pilot filter, diaphragm, seal, float assembly and pipeline connection periodically.
• Remove sediment, mineral deposits or foreign material if water flow becomes restricted.
• Protect exposed pipelines and valves against freezing in cold-climate livestock facilities.

Q: Why is this valve suitable for installations with limited space?
A: The compact weighted float and pilot-operated diaphragm system eliminate the need for a large conventional float arm, allowing high-flow water control in relatively small valve compartments.

Q: Is it suitable for commercial pig farms?
A: Yes. It can be integrated into suitable pig drinking troughs, header tanks and farm water systems where automatic filling and high refill capacity are required.

Q: Does the valve require electricity?
A: No. Float movement and water pressure operate the pilot and diaphragm mechanism mechanically.

Q: Can it operate with pump-supplied water?
A: Yes. The positive on/off design is particularly suitable for pressure-fed and pump-supplied systems when the operating pressure remains within the specified range.

Q: What inlet sizes are available?
A: Common configurations include 1/2", 3/4", 1" and 1-1/4" inlet sizes with BSP or NPT thread options.

Q: How does the valve help reduce water hammer?
A: The diaphragm valve is designed to close progressively rather than stopping high flow abruptly, helping reduce hydraulic shock in the supply line.

Q: Can configurations be supplied for livestock projects and distributors?
A: Yes. Inlet size, connection configuration, packaging and other project requirements can be discussed according to the intended farm application.
