PVC Spring Loaded Foot Valves

Description

Foot Valves are used to connect to a male thread to draw water from a water source only allowing water to travel in one direction and restricting large sediment from entering the pipe system. Connecting to male BSP threads, they are easy to install and offer excellent durability, reliability and strength. Australian made for Australian conditions.

Foot valves are designed to comply with the following standards and undertake a range of tests to ensure they comply with these standards.

STANDARDS

• AS 1722.1: Pipe threads of Whitworth form part 1: sealing pipe threads.
• ISO7: Pipe threads where pressure tight joints are made on the threads

TESTS

• Shut Off Test: Valves are tested for shut off against a hydrostatic water pressure of 16 kPa (2.3 psi) or 0.16 bar and 200 kPa (29 psi) or 2 bar.

SYSTEM DESIGN CONSIDERATIONS

• Minimum Sealing Pressure: 20 kPa (3 psi) or 2 m or 0.2 bar of head at 20°C.
• Maximum Operating Pressure: 1400 kPa (200 psi) at 20°C.
• Threads: All threads are BSP (Whitworth form).
• Sealing threads: We recommend sealing threads with PTFE tape. Other approved sealants for plastic materials can be used providing the sealant does not enter the valve where it may cause damage.
• Operating temperature: Connection is cold water (less than 20°C) rated.
• Weathering: All plastic materials used contain pigments to provide excellent protection against degradation from ultra-violet (UV) radiation. However long-term continuous exposure to UV is not recommended and plastic components should ideally be protected.
