Brass Spring Check Valve

Brass Spring Check Valve can be defined as the armatures that prevent the fluid in the system from returning back. It is a kind of safety element and such products are needed in many areas. The product, which is produced in a very special way, provides 100% sealing. Due to the needs of the system and its intended use, it has to meet various criteria.

Although its working principle is quite simple, it basically acts by spring force. The decrease in pressure in the system ensures that the spring force is closed. The product, which can be used in both horizontal and vertical positions, is used in many sectors with its innovative features. It has a wide range of uses, especially in hot and cold water applications, compressed air installations.

What is a Brass Spring Check Valve and What Does It Do?

Brass spring check valve is a kind of safety equipment that acts with a spring mechanism and provides unidirectional movement of liquid or gas in the system. It is also observed that it is used instead of complicated fixtures, since its operational safety is quite high. The working principle of check valves is quite simple.

The disc in the product can move in one direction on the hinge pin in one direction. As the fluid moves in one direction, the disc opens and passes. In case of reverse flow, the disc is closed and the movement of the fluid is stopped. This allows the formation of one-way fluid movement within the system, making it possible for the system to operate smoothly.

What is a Brass Spring Check Valve?

Brass spring check valve, which is needed in different areas, especially in industrial areas, pumps, home use, has a system that enables long-term use. Reverse flows occurring in a system can cause damage to materials such as pumps and valves in the system. This prevents the system from working effectively.

Spring check valves have a single inlet and outlet and there is a mechanism that allows the fluids to move in one direction. The main factor that makes the check valves work is the pressure difference. If the pressure in the inlet part of the valve is higher than in the outlet direction, the valve opens. Otherwise, the valve closes. In this way, the liquid or gas in the system moves in one direction and the integrity of the system is ensured.

What Does Brass Spring Check Valve Do?

The brass spring check valve, which prevents the fluids passing through the installation from returning by going through a certain direction, has the features that can be listed as follows:

  • Working pressure between DN 15-50 is 16 bar, DN 65-80 is 10 bar.
  • Other types of check valves do not have clapper breakage problems.
  • They offer a comfortable use as they can be used in horizontal and vertical positions.
  • The ABS plastic conical flap, which is placed vertically to the flow direction on the body, has a 100% leakage feature.
  • FAF branded brass products made of MS58 brass are used.
  • It can be used conveniently and comfortably with its long service life.
  • When the flow starts, the disc is pulled back and the flow is allowed.

Each of the specified features makes it possible to use such check valves in many areas. Since it is manufactured in a special way, it ensures the safety of the parts in the installation.

Where Brass Spring Check Valve Is Used?

The usage areas of the brass spring check valve, which has a spring mechanism and moves with this mechanism, are quite high. It is possible to list the usage areas of such products in general under the following headings:

  • Pumps: Check valves are needed for some pump types.
  • Home use: small check valves can be used inside drip irrigation, sprinkler, irrigation emitters.
  • Industrial areas
  • Heating and cooling systems
  • Compressed air installations

In each of the specified areas, check valves with a spring mechanism are preferred. It is possible to state that such products attract attention thanks to their easy installation and comfortable use features.,
