Double exccentric butterfly valve

Description

The double eccentric valve with reducer is an essential piece of equipment in fluid transportation systems, used to control flow and pressure in industrial plants, water supply networks, irrigation systems and other applications requiring high reliability.

This type of valve is characterized by a double eccentric design, which means that its axis of rotation is offset from the center of the disc and from the seal. This configuration reduces friction between disk and seal, resulting in minimal wear and extended component life. Also, thanks to this mechanism, the valve requires less force to maneuver, providing excellent sealing and smooth operation even under high pressure conditions.

An important element of this equipment is the reducer, which facilitates manual or motorized operation of the valve through a gear system. It reduces the effort required to open and close the valve, allowing precise control of the liquid flow. The reducer is ideal for applications where fine flow adjustments are required or where manual force would be insufficient for direct actuation.

Materials used in the construction of the double eccentric valve are chosen to ensure resistance to corrosion, abrasion and temperature variations. Usually the body is made of ductile cast iron or stainless steel and the seals of EPDM or NBR ensure a perfect seal. The inner and outer surface is protected with a layer of epoxy paint to prevent degradation caused by chemicals or the environment.

Thanks to its innovative design and high reliability, the double eccentric valve with reducer is the optimal choice for applications requiring safe and efficient fluid control. It offers the perfect balance between performance, durability and ease of operation, and is essential for maintaining a long-lasting fluid system performance.
