Triple Duty Valve

TDV Series

Our ETDV triple duty valves are primarily required on the discharge side of a centrifugal pump in a hydronic heating or cooling system. The valves functions as a shut-off valve, spring loaded silent check valve, and balancing valve.

Our ETDV has an automatic and silent operation. The disc will open when the line pressure is approximately 1/4 PSI. As the line pressure approaches zero, the spring will close the disc to prevent flow reversal and water hammer. The flow through the valve can be adjusted from bubble tight shut-off to full flow by the acme rising stem.

The center guided soft seal disc ensures that there is no leakage. The rising stem design includes an adjustable position indicator for accurate disc positioning for throttling service. The unit comes with a standard gauge taps at both the inlet and outlet sides and a NPT drain plug.

Our ETDV’s are constructed from rugged cast iron castings that are machined to exacting specifications. These bodies have drilled flanges that are in accordance with ASME B16.1.

Tank Insulation

Elbi sprayed-on rigid insulation with acrylic topcoat exceeds ASHRAE 90.1 requirements with 2” of high-density polyurethane foam with an “R” value of R-16. SPF meets requirements for California Title 24. Elbi spray foam insulation has the best fire spread rating with a class I foam with less than a 25-flame spread rating suitable for boiler room applications.

The 100% acrylic topcoat is formulated for applications over spray polyurethane foam and is designed to withstand extreme weather and a full range of environmental conditions. The 2 component polyurethane foam is applied at ambient temperatures, directly to the vessel in the desired thickness. The 2-coat topcoat is then applied from a high-pressure spray gun and allowed to dry between applications. Metal jacketing is also available.
