Float valve – 3/4 inch

Product Description

A float valve is a mechanical device that automatically controls water levels in tanks, reservoirs, or troughs. It uses a float that rises and falls with the water level. When the water drops, the valve opens to allow refilling. When the water reaches the desired level, the valve closes to stop the flow.

Float valve – 3/4 inch

This listing covers high-quality 3/4-inch float valves, a standard size for various applications. These valves feature a durable metallic body, reliable sealing mechanism, and a float arm designed for longevity. They are ideal for water storage tanks, water towers, livestock troughs, and industrial and agricultural uses.

What are the common types of 3/4 inch float valves?

Gunmetal Body models like the Nieruf SW03 are made from gunmetal with EPDM seals, a plastic float, and a male threaded connection. They are designed for water and other neutral liquids.

Stainless Steel Body models like the Nieruf SW06 offer a stainless steel body and float with FKM seals for aggressive liquids and fully desalinated water.

Brass Body models like the BOB R900-3 male inle/4 feature heavy-duty cast brass with Nitrile seals and 3/4″ MNPTt and outlet. They are commonly used in car washes and cooling towers.

What are the key specifications?

Thread size is 3/4 inch with BSP or NPT connections. Body materials include brass, gunmetal, or stainless steel. Seal materials include EPDM, FKM, Buna-N, or Nitrile. Temperature ranges are up to 80°C for EPDM models, up to 190°C for stainless steel/FKM models, and up to 82°C for brass models. Maximum working pressure is typically up to 12 bar or 100 psi for some brass models. Flow rate ranges from approximately 4.0 to 5.7 m³/h depending on model. Float materials include plastic, copper, or stainless steel.

What factors should I consider when choosing a float valve?

For fluid type, standard water applications suit gunmetal or brass valves. Aggressive liquids or high-purity water require stainless steel models. For temperature, the seal and body material determine the maximum operating temperature. EPDM suits general hot water up to 80°C while FKM handles higher temperatures up to 190°C. For connection type, ensure the correct thread type between BSP or NPT. For float type, plastic, copper, or stainless steel floats perform differently in various conditions. For installation, the valve body can be horizontally or vertically mounted depending on the model.
