Ultra-High-Flow Livestock Float Valve

• Ultra-high-flow design with a nominal product class of up to approximately 600 L/min.
• Pilot-operated diaphragm mechanism provides high water delivery from a compact valve body.
• Designed for above-water installation in livestock troughs, tanks and cisterns.
• Horizontal or vertical mounting provides flexibility for different farm water-system layouts.
• Corrosion-resistant engineering materials are suitable for demanding agricultural environments.
• Slow-closing diaphragm action helps minimize water hammer in high-capacity pipelines.
• Float position can be adjusted without tools for convenient water-level setting.
• 20-60 mm water-level differential depending on inlet pressure and operating conditions.
• Valve body can be unscrewed from the inlet tail for easier access to the valve seal.
• Integrated lock-off function allows the valve to be held in the closed position during servicing.
• Accessory port supports compatible anti-freeze protection equipment where required.

• Valve Body: Glass-filled nylon housing provides mechanical strength and corrosion resistance.
• Pilot Valve: Responds to float movement and controls pressure within the main valve chamber.
• Main Diaphragm: EPDM diaphragm opens and closes the primary high-flow water passage.
• Float Assembly: HDPE float follows changes in the trough or tank water level.
• Adjustable Arm Assembly: Transfers float movement to the pilot mechanism and allows operating-level adjustment.
• Internal Components: Acetal components provide dimensional stability inside the control mechanism.
• Seal: TPU sealing component supports reliable shut-off.
• Filter: PP/nylon filtration components help protect the pilot flow passages.
• Metal Hardware: 304 stainless steel springs, bolts, nuts, pins and screws provide corrosion resistance.
• O-Rings: Nitrile seals are used at relevant internal joints.
• Removable Inlet Tail: Allows easier servicing and selection of different connection sizes.

• 32 mm, 40 mm or 50 mm inlet configurations
• 1 1/4", 1 1/2" or 2" connection sizes
• BSP or NPT thread configurations according to regional requirements
• Float-arm arrangement according to required operating water level
• Installation configuration according to trough or tank structure
• Pipeline connection accessories available upon request
• Bulk packaging and project supply according to procurement requirements

• Install the standard valve above the water level; this configuration is not intended for underwater mounting.
• Select the correct inlet size according to pipeline diameter, available supply pressure and required refill capacity.
• The valve can be installed horizontally or vertically according to the trough or tank arrangement.
• Position the inlet appropriately above the overflow level to reduce back-siphoning risk and comply with applicable local plumbing regulations.
• Flush new water pipelines before installation to remove construction debris.
• Adjust the float position to establish the required operating water level; adjustment can be completed without special tools.
• Confirm that the float and arm move freely throughout the complete operating range.
• Inspect filters, diaphragm, seals and moving components periodically, especially where water contains sediment.
• The valve can be unscrewed from its inlet tail to simplify access to the valve seal during maintenance.
• Use the integrated lock-off function when servicing the trough, tank or valve assembly.
• For freezing climates, compatible frost-protection accessories can be considered according to local climate and farm conditions.

Q: What makes this valve suitable for high-demand livestock watering?
A: Its pilot-operated diaphragm mechanism is designed for very high water delivery, allowing large troughs and tanks to recover quickly after heavy livestock consumption.

Q: Is 600 L/min available under all operating conditions?
A: No. The 600 L/min figure represents the valve's high-flow product class. Actual delivery depends on inlet pressure, pipe diameter, inlet size, upstream restrictions and overall water-system design.

Q: Can this valve be mounted underwater?
A: No. The standard configuration is intended for above-water mounting. A dedicated underwater valve configuration should be selected when submerged installation is required.

Q: Can the valve be mounted vertically?
A: Yes. The design supports horizontal or vertical mounting according to the tank or trough configuration.

Q: How is the required water level adjusted?
A: The float position can be adjusted mechanically without special tools, allowing the shut-off level to be matched to the installation.

Q: How does the valve reduce water hammer?
A: The pilot-operated diaphragm closes progressively rather than stopping the full water flow abruptly, helping reduce hydraulic shock in high-capacity pipelines.

Q: Is it suitable for commercial pig farms?
A: Yes, particularly for central water tanks, header tanks and compatible high-demand trough systems. Final valve selection should consider animal numbers, peak water demand, supply pressure and pipeline capacity.

Q: Are different inlet sizes and threads available?
A: Yes. Multiple metric and imperial inlet sizes with BSP or NPT thread configurations can be supplied according to project requirements.
