Wafer Butterfly Valve is produced to protect the system against bidirectional pressure difference in the fluid in a system. The sealing valve prevents backflow in the system. It is used within the basic working principle. Since it has a wide usage area, it is possible to observe such valves in different areas.

Valve with flat flange surfaces performs with a tight-fitting gasket on the surface. The disc is placed in the gasket and thus, protection is provided in the system against two-way pressure difference. Wafer butterfly valve, which draws attention with its innovative features, has a structure that enables long-term use.

What is a Wafer Butterfly Valve and What Does It Do?

Wafer Butterfly Valve, which draws attention with its many features, is one of the butterfly valve types with a national design. Thanks to their compact dimensions, these types of valves enable practical use and also provide effective protection of the system. It is basically designed to protect the system against bidirectional pressure difference that may occur in the fluid in a system.

The general characteristics of this type of valves are as follows;

• Pressure losses are minimal.
• It has impermeability feature.
• Easy to open and close.
• Since it has a light design, it makes it possible to use comfortably.
• Since it takes up little space, it makes space saving possible.

What is a Wafer Butterfly Valve

Wafer Butterfly Valve, which is a type of butterfly valves, provides tightness during flow and prevents leakage due to pressure difference in the system. Its mission is important and therefore such valves are needed in many areas. Since each product is equipped with various disc materials, it has a compact working principle.

Designed in EN 593 standard, the product also has Wafer Type ISO 7005-1 EN 1092-1 connection type. It is known that they are used in many areas such as hot and cold water lines, water treatment systems, industrial areas.

What Does a Wafer Butterfly Valve Do?

Wafer Butterfly Valve is a type of valve with sealing feature. It contributes to the regular flow of the system. In addition, it prevents leakages in the flow in the system with its sealing feature. Wafer butterfly valves generally include the following features:

• The valve can be removed from one side as it is practical to install. This makes maintenance effortless.
• Epoxy bonded by electrostatic fusion is used in the inner and outer parts of the valve body.
• It has EPDM, NBR and VITON gasket options. In this way, it is known that it can be used easily in different fluid types.
• There is EPDM rubber inside the valve body.
• It has low operating torque. In addition, it is possible to say that it has a long service life.
• Protects the system effectively against two-way pressure difference.

The features of the product make this type of valve preferred in many areas. In addition, with its durable structure, the Wafer butterfly valve has long-term use.

Where is Wafer Butterfly Valve Used?

Wafer Butterfly Valve can be used in different areas and fluid levels as it has an innovative feature. Some of the areas where such valves are frequently used can be listed as follows:

• Water treatment plants
• Hot and cold water lines
• Cooling water pipelines
• Sea water applications
• Pipelines
• Treatment plants
• Food and paper industries

Wafer butterfly valve, which attracts attention with its wide usage area, makes high performance possible with its innovative features. In addition, it is designed to be used for a long time.
