Grooved Ends Butterfly Valve With Tamper Switch Fig. 21 UL/FM

Our UL/FM Grooved Butterfly Valve with Grooved Union System (Victaulic®) is a two-way, concentric valve that provides a self-centering union that allows for greater flexibility of movement and quick, secure installation, making repairs and maintenance easy. . In addition, they guarantee a leak-resistant, watertight connection and an alternative to pipe joints without the need for welding or threads. Grooved ends are machined to FM/UL standards. The slotted joint system reduces noise and vibrations throughout the installation. It is economical, easy to handle and adapts perfectly to low and medium pressurization systems. It is a valve that is supplied in its standard construction with a stress gear box with two limit switches for fire protection applications at a maximum of 80°. It is certified according to UL and FM. It is a very popular quarter-turn, two-way, resilient-seated valve for on-off or modulating services. It is centered (concentric) whose axis is located in the center of the disc, which is centered on the inside with respect to the X, Y axes. The tightness is optimal and it is a suitable valve for low pressure ranges. It is light, takes up little installation space, has a lower cost, and works quickly. The disc is connected to a shaft that when the valve opens the disc rotates to allow the passage of fluid and closes when the shaft rotates the disc to a position perpendicular to the direction of flow. It has a flange in its upper part in accordance with ISO 5211, which is the international standard that specifies the requirements for fixing part-turn actuators to industrial valves. IMPORTANT: Both during storage and when assembling it, the Butterfly valve must always be ajar, to avoid in the first case deformations of the elastic seat (elastomer) and during assembly to avoid tensions or forces that prevent proper centering and fastening that Do not let the valve close properly.
