Product description
Check valves (check valves) are used to provide one-way flow and prevent return, they are an indispensable part of automatic extinguishing systems. Although there are many types, flap types are used in fire systems. The flow direction, which is important for assembly, is indicated by an arrow on the body. Check valves allow one-way passage of water in the system. Since pressure losses are high, it is not desirable to use many check valves in fire installations.
Production Dimensions : Ø50-Ø250 (2”-10”)
Swing Check Valve Wafer
Swing Check Valve Wafer is a type of check valve used in water systems to provide flow in one direction and to prevent backflow of water. Today, it has a wide range of uses, especially automatic fire extinguishing systems. At the same time, the swing check valve wafer has different models that can be used for different purposes. These check valves, which have a disc-shaped structure, are mounted by positioning them at the midpoint of two flanges. It is possible to easily complete the assembly with simple bolts. There is a small hole in the middle of the disc-shaped check valve. The material, called the clapper, positioned on this hole, can be opened at an angle of 90 degrees to the right or left according to the demands.
Swing Check Valve Wafer is made of stainless material. In addition to having a high level of durability, it is suitable for long-term use. In flanged systems, the basic duty of the swing check valve wafer is to provide control. It can be produced in different sizes and it is possible to find a suitable model for almost every installation.
Swing check valve wafers must be installed by a specialist in the field. Although the assembly process may seem simple, it should not be forgotten that check valves have an important role in order for the system to work properly. It is recommended to effectively clean the pipeline with gas or steam before installation.
Swing Check Valve Wafers are valves that stop backflow and provide flow in a single direction as requested. The working principle of these valves is that the flaps in the valve act in the direction of the water flow direction of the system and provide a stable water flow. If the flow stops, it changes its axis according to the flow direction and prevents the return of water.
Swing check valve wafers have 100% tightness assurance. Body, disc and springs are completely made of stainless steel. Swing check valve wafers can be mounted in horizontal or vertical position according to the demands. It does not require any maintenance and can be preferred in order to prevent possible leaks in water lines.
Swing Check Valve Wafer has the function of preventing water flow in the system in one direction, while preventing its return in the opposite direction. Having a one-way function, these check valves do not need any maintenance. However, some basic points should be considered in the use of swing check valve wafers.
Especially low air temperatures have a significant deformation effect on the valves. Therefore, in case of such temperature drops, insulation should be made. Freezing of the water in the valve due to low temperatures may cause problems in the system as well as damage other equipment. At the same time, measures should be taken against limescale and rust in order for the installation to continue working efficiently.
Çalpara Checkvalf Wafer has a wide range of applications and uses. Although it is used in aqueous systems, it can also be suitable for other installations for different purposes. The usage areas of Çalpara check valve wafers are as follows, in general terms:
In addition to all these areas, swing check valve wafers can be used in all kinds of water installations where one-way flow is required. In addition, they are extremely ideal valves for use in order to prevent minimal leaks in the installation. Maintenance-free structures will provide significant advantages in use.
