  • Thread connection : (G, Rc, RP) BSP, NPT
  • This valve has a brass body with a stainless steel spring for long-lasting durability.
  • USE: This valve is used to prevent the backflow of fluids
  • Check valve non-return valve female to female.
  • Suitable for water and central heating installations. It allows fluid (liquid or gas) to flow through it in only one direction.

The check valve is to rely on the flow of the media itself and automatically opens and closes the valve flap, used to prevent the media back to the valve, also known as the water check valve, counterflow valve, and back pressure valve. The check valve is automatic, and its main role is to prevent media backflow, prevent the pump and drive motor reversal, and release container media.

 “Check Valves” are the ones that permit fluid to move in one direction only. They prevent the backflow of water or other liquids. Brass is a soft metal that offers more corrosion resistance than traditional metals. Therefore, using brass in check valves makes them more sustainable and increases their life span. Hence, we can quote that “Brass check valves” are the best option to avoid backflow or restrict contamination in fluids.


Applications of Brass Check Valve:

Brass check valves are well-known worldwide for their characteristics and excellence. Here are the top picks where they are applied for use.

Brass valves have many different types, such as ball valves, garden tap, check valve, strainer, angle valve, gate valve, foot valve, and drain valve. The radiator valve and thermostatic mixing valve are works for water temperature. All of these valves are work for water plumbing systems, plumbing repair, and installation. So have to let water shut-off and shut-on. Some heating systems are related to hot water and cold water mixing for temperature control and stability. Our intelligent valves are functional. There are applications in commercial, residential, and industrial areas.

Underfloor heating radiant pex manifolds are usual for residential water distribution in a household, and it's top-rated in the home building industry. Manifold plumbing systems control hot and cold water that feeds flexible PEX supply lines to individual fixtures. Then water temperature is warm and stable in each room.
