Heavy-Duty High-Temperature Float Valve

• High-flow design for rapid automatic replenishment of tanks and water systems.
• Designed for water temperatures up to 80°C / 176°F.
• Compact, robust construction for demanding agricultural and industrial applications.
• Corrosion-resistant valve body and internal materials support long service life.
• Pilot-operated diaphragm structure provides efficient high-capacity water control.
• Slow-closing action helps reduce water hammer in pressurized water pipelines.
• Float position can be adjusted without special tools.
• Approximately 20-60 mm water-level differential depending on inlet pressure.
• Supports multiple mounting configurations for different tank and trough structures.
• Integrated lock-off function allows the valve to be held closed during servicing.
• Compatible port for optional frost-protection equipment.
• Multiple inlet sizes, tail configurations and float options are available.

• Valve Body: High-strength Grivory construction designed for mechanical durability and elevated-temperature applications.
• Internal Control Components: TE21 acetal components provide dimensional stability and reliable mechanical operation.
• Diaphragm: EPDM diaphragm controls the primary water passage.
• Valve Seal: Santoprene sealing element provides reliable automatic shut-off.
• Filter: PP/nylon filtration components help protect pilot passages from debris.
• Float: HDPE float responds directly to changes in water level.
• Float Cord: Polyester construction provides durable mechanical connection.
• Hardware: Springs, bolts, nuts, pins and screws are manufactured from 304 stainless steel.
• O-Rings: Nitrile sealing components are used at relevant internal connections.
• Tail Assembly: Short-tail, long-tail and detachable configurations support different installation requirements.

For direct livestock drinking-water applications, operating temperature, water quality and system configuration should comply with applicable animal-welfare, drinking-water and local plumbing requirements.

• 15 mm, 20 mm, 25 mm and 32 mm inlet configurations
• 1/2", 3/4", 1" and 1 1/4" connection options
• BSP or NPT threads according to regional requirements
• Short-tail or long-tail inlet configuration
• Detachable-base configuration available upon request
• 125 mm standard float with optional 70 mm or 95 mm float configurations
• Top, side or bottom entry according to tank structure and installation requirements
• Bulk packaging and project supply according to procurement requirements

• Select the mounting position according to tank geometry, water level and applicable local regulations.
• Where required for back-siphon protection, maintain an appropriate air gap between the inlet and overflow level.
• Flush new pipelines before installation to prevent construction debris from entering the pilot mechanism.
• Select the correct inlet diameter according to available pressure, pipeline capacity and required refill rate.
• Ensure the float and actuator mechanism can move freely without interference from tank walls or internal fittings.
• Adjust the float position to obtain the required shut-off water level; no special adjustment tools are normally required.
• Use the lock-off function when servicing the valve or associated tank equipment.
• Inspect the pilot filter, diaphragm, seals and float assembly periodically.
• Remove mineral deposits, sediment or foreign material where water quality may affect valve operation.
• Inspect threaded connections, backnuts and sealing washers during scheduled maintenance.
• For cold-climate projects, compatible frost-protection accessories may be considered according to local climate and farm conditions.

Q: What is the main difference between this valve and a standard livestock float valve?
A: This configuration is designed for greater mechanical strength and higher water-temperature capability, making it suitable for demanding utility, cleaning, cooling and process-water applications.

Q: What is the maximum operating water temperature?
A: The specified maximum operating temperature is 80°C / 176°F.

Q: Does the valve require electricity?
A: No. Water-level control is performed mechanically through the float, pilot mechanism and diaphragm assembly.

Q: Can the valve be mounted in different positions?
A: Yes. Side-entry, bottom-entry and top-entry arrangements are available, although installation must comply with local plumbing and backflow-prevention requirements.

Q: How does the valve help reduce water hammer?
A: The diaphragm closes progressively rather than stopping full pipeline flow instantaneously, helping reduce hydraulic shock.

Q: Can the water level be adjusted?
A: Yes. The float position can be adjusted mechanically to suit the required operating water level.

Q: Is it suitable for commercial pig farm projects?
A: Yes, particularly for utility water tanks, wash-down systems, cleaning equipment, header tanks and other compatible farm water-control applications. Final selection should be based on pressure, flow, water temperature and installation conditions.

Q: Are different inlet sizes and configurations available?
A: Yes. Multiple inlet diameters, BSP or NPT threads, tail configurations and float options are available according to project requirements.
