The triple-eccentric valve is a special component, a delicate engineering design designed to eliminate the friction that originally exists between the disc sealing ring and the body. Unival works with high-tech triple-eccentric valves, manufactured with all the necessary quality parameters and in accordance with established market standards.

The main purpose of the triple-eccentric butterfly valve, and its major distinguishing feature compared to other types of valves, is its high-quality seal. Furthermore, the component prevents wear and, consequently, leaks and damage.

What should be highlighted in the triple-eccentric valve?

The triple-eccentric valve is made with the highest quality and features redundant mechanisms to prevent leaks and enhance sealing. Therefore, it features triple eccentricity, a reinforcement and repeat mechanism, to ensure an efficient, fully reinforced seal.

Because of its structure, line maintenance can be performed without the need to remove the valve, which ensures faster repair work and greater agility in carrying out activities.

The seal is provided by the seal, and the valve body is produced in a single piece. The valve body is cast, increasing the rigidity necessary to ensure the seal and provide maximum protection against leaks.

The valve disc features a sealing ring made of alternating layers of an alloy containing graphite that resists corrosion. The layers are crucial to the component's construction, as each layer provides an individual seal, ensuring the system is not damaged.

The valve features a rigid, uniquely designed shaft coupled to the disc via cone-shaped pins, a system responsible for maintaining force balance. The shaft is kept enclosed within the disc, protecting it, facilitating flow capacity and reducing system pressure.

The triple-eccentric butterfly valve features hardened bushings to resist corrosion. In the stuffing box, the O-rings allow discharge, as well as providing additional sealing and leak control.

Unival Tri-eccentric Valve

Unival's Tri-Eccentric Butterfly Valve features innovative technology, offering a range of benefits and advantages. The valve's main attraction is its sealing ability, as the metal-to-metal combination prevents wear that could cause leakage.

The part withstands high temperatures, is quickly and easily maintained, and can be repaired in the field, among other benefits.
