1. Lower the valve into the open pipe work with the disc in the 10 open position. Valves with non-spring actuators are shipped in this position. 2. Once the valve is placed in the pipework, turn the disc to the full-open position. Gradually remove the flange spreaders. 3. Center the valve body to the flanges and tighten the bolts hand-tight.
Name of Product Triple Eccentric Butterfly Valve Features Axis center of the stem deviates from the disc centerline and the body centerline, and the disc is eccentric by angled an oblique cone, this construction reduces friction of the seat ring and prolong its lifespan.

A butterfly valve is a quick opening, rotational motion valve that uses a metal, circular disc (vane) to start, stop or regulate flow in a pipe. Typically, a simple 90 rotation of the valves handle either opens or completely closes the valve as the vane seals itself against the seats in the valve housing.

The GAR-SEAL valve meets SIL 3 (mean probability of failure 10-4 to 10-3). Stem seals are important because they prevent the media from escaping up and out the stem. If the media escapes out the stem, it can be a safety issue; it can contribute to fugitive emissions, and it can damage actuators or the equipment running the valve.
The stem, packing gland, actuator superstructure and all fasteners are stainless steel for corrosion resistance. Internal wearing parts of the valve are renewable at a fraction of the cost of a new valve. These parts include a tool steel inlet cone, a tool steel gate and a unique design tool steel U-vee port.
