Brass spring loaded threaded check valve Int/Int Pn 16

Spring-loaded brass coupling check valves PN 16 are a type of check valves that are used to prevent backflow of the working medium in pipelines. They are made of brass, which ensures high strength, corrosion resistance and durability. The main feature of such valves is the presence of a spring that automatically returns the valve to the closed position in the absence of pressure or flow of the working medium. This type of check valves is widely used in water supply systems, heating systems, pumping stations and other utilities. Brass as a body material makes the valve suitable for working with water, oils and other non-aggressive liquids.

The principle of operation of a brass spring-loaded valve

• When the pressure of the working medium (for example, water) exceeds the resistance of the spring inside the valve, the valve opens, allowing the working medium to move in one direction.
• If the flow stops or the pressure drops below the spring resistance level, it automatically returns the valve to the closed position. This prevents the medium from moving back.

Installation

They are installed both horizontally and vertically, provided that the direction of the working medium flow is observed according to the arrow on the body.

Advantages of brass spring-loaded valves

1. Corrosion resistance: Brass has a high resistance to water and most non-aggressive liquids.
2. Compact design: Spring-loaded models have small dimensions compared to other types of check valves.
3. Ease of installation: The coupling connection allows for quick installation of the product without the need for complex tools.
4. Automatic operation: Does not require external control due to the built-in spring.
5. Wide range of applications: They are used both in domestic water supply systems and in industrial installations.

Where are brass spring-loaded valves used?

1. In cold and hot water supply systems:
   • To prevent backflow of water.
2. In pumping stations:
   • Installed after the pump to hold the water column when the equipment is turned off.
3. In heating systems:
   • Protect risers from squeezing the coolant between floors of the building.
4. In autonomous water supply systems:
   • Used after borehole pumps to prevent water leakage back into the well or borehole.
5. In industry:
   • Used for working with oils or other media at moderate pressures and temperatures.
