LUG Butterfly Valve is a type of valve suitable for operation in low pressure systems. The valve, which is mounted with a two-way screw connection, has an easy installation. It is known that the valve, which is preferred in treatment plants as well as industrial plants, incorporates innovative and technological features.
Butterfly valves, which have a wide area of use because they provide a light and economical use, are designed according to the EN 593 standard. In addition, the connection feature is LUG type EN 1092-2 / ISO 7005-2. Designed using electrostatic powder paint, the product is ideal for long-term use.
What is a LUG Butterfly Valve and What Does It Do?
LUG Butterfly Valve is one of the valve types used in fluidity control and can be opened and closed in a practical way. Innovative features and easy use make it possible to prefer this type of valve in many areas. The product, which is generally used in small diameter systems with low pressure, makes it possible to save space.
The product can be disassembled from one side and the other side can remain closed during this time. This feature can be considered as one of the advantages of the product. During maintenance, a part of the valve can be removed and maintenance operations can be applied in a practical way. In addition, after the maintenance is completed, it can be reassembled into the system and the use of the product can be continued. In addition, double-sided screw connection is preferred in its assembly.
What is LUG Butterfly Valve?
LUG Butterfly Valve, which is among the butterfly valve types, is basically an outlet system used in installations with fluid. Fluids such as liquid, gas, partial or viscose can be kept under control with LUG butterfly valves, which take up very little space in the system. Their small footprint compared to other valve types makes it possible to use them in many areas.
This type of valve, which has been in use for a long time, incorporates features reminiscent of a 3-piece ball valve design. The most important feature of LUG butterfly valves is that one end of the line can be removed comfortably and practically without affecting the opposite side. These types of valves are similar to 3-piece ball valves.
What Does the LUG Butterfly Valve Do?
LUG Butterfly Valve, which has a very wide usage area, draws attention as one of the valve types that is easy to clean and maintain. The general features of such valves, which have many features, can be listed as follows:
Each of the specified features makes it possible to use the product in an easy and practical way. In this way, it has a wide usage area. In addition, each of the materials used in the system makes it possible for the product to be long-lasting.
Where is the LUG Butterfly Valve Used?
LUG Butterfly Valve draws attention as a valve type that can be preferred in different areas. Usage areas may vary and it is possible to say that it is generally preferred in the following areas:
Incorporating innovative features, the LUG butterfly valve is preferred in many areas as an easy-to-clean valve. In addition, the assembly can be done in a practical way.

FEATURES
Equipped with various disc materials and EPDM, NBR and VITON gasket options, it can be used in various fluid types and different applications. DN350 and above butterfly valves; The inside of the valve body is vulcanized with EPDM (Elastomer) rubber.
Compared to other valve types, it offers light weight, easy installation and cost advantages with its compact dimensions.
The flap design is designed to create minimum pressure and as a double shaft.
DN350 and above have single shaft design.
The inner and outer surfaces of the valve body are coated with an electrostatic fusion bonded epoxy (FBE) / baked powder epoxy coating. It provides trouble-free operation and longer life in harsh conditions. It is DN350 and above industrial wet epoxy.
Higher coating thicknesses are available on request.
DN 350 diameter and above are supplied with a standard gear box, and DN 300 diameter and below are optionally delivered with a gear box, so they are supplied with a manual lever.
Electric or Pneumatic actuators fit directly onto the valve top flange (ISO 5211). No additional spacers are required.
There is no mounting problem in PN6-10-16 and Class 150 flange norms.
It is extremely easy to maintain.
Four flange mounting half-lugs ensure correct valve position during assembly
The valve body and disc are machined with high precision, resulting in low operating torque and long service life.
