BASIC ANTI-SYPHON PROTECTION FOR 2 INCH TANK FILL LINES
Cast iron anti-syphon valve for fuel tanks. DN50 (2 inch) BSP female connections. Prevents reverse flow and protects stored fuel from contamination.
Stops reverse flow
Fuel tanks need protection from syphoning. This valve sits inline on your fill line and closes when flow tries to reverse. Gravity or system pressure can otherwise pull fuel back through the fill point and contaminate or drain the tank. One-way operation keeps fuel where it belongs.
Cast iron, 2 inch BSP
DN50 (2 inch) BSP female threads match standard tank inlets and fill hoses. Cast iron body handles diesel, petrol, and kerosene without issue. Rated for up to 1.5 metres of head pressure, which covers most gravity-fed fill systems on site tanks and bowsers.
