Auto Shut-Off Stainless Float Valve

This 2-piece float valve set delivers reliable, self-regulating water level control using only hydraulic force — no electricity, sensors, or moving parts beyond the float and plunger. Constructed from food-grade stainless steel throughout, including body, float arm, and internal components, it ensures safety for potable water applications. Each valve has a 1/2 inch BSP male thread inlet, and is supplied with threaded adapters for 3/4 inch and 1 inch pipes. Dimensions per unit: approx. 12 cm × 5 cm × 8 cm; weight: ~350 g. Operating temperature range: 0°C to 100°C. Includes integrated stainless steel mesh filter and two pieces of Teflon tape for leak-proof sealing on straight threads. The mechanism responds directly to water level changes: falling level lowers the float, releasing water pressure to lift the silicone-sealed plunger and initiate flow; rising level lifts the float, reseating the plunger to stop flow precisely at the target height. Ideal for overhead tanks, livestock watering systems, decorative fountains, and irrigation reservoirs. Installation requires no tools beyond a wrench; the side and upper inlet variants allow adaptation to varying tank geometries and inlet positions — significantly increasing real-world usability versus fixed-orientation valves.
