PRODUCT DESCRIPTION

BALL VALVES

Ball valves are used for fill and drain purposes in larger transformers. These high quality units feature a chrome ball, nested within a Teflon® seat, thus assuring a positive, leak-tight, wear-free fit.

Full opening and shut-off is accomplished with a 90 degree turn of the handle. Models may be obtained with a sampler valve pre installed and tested at the factory.

GLOBE VALVES

Globe valves are the best design for transformer applications for both fill and drain applications. The Teflon® seal closes upon its seat securely, not suffering any rotational abrasion, due to the swivel disc technology we employ. The valves may be opened and reclosed repeatedly without concern for wear. All brass valves shown, unless identified as “gate”, “ball” “radiator” or “sampling device” are of the globe design.

SAMPLER VALVES

Sampler valves facilitate the need to extract samples of transformer oil for testing. They are usually mounted on the drain valve, but some models can be mounted as a plug in the end of the drain valve. They feature precise control in metering the oil into the test apparatus.

RADIATOR VALVES

Radiator valves are welded or bolted to the transformer tank, and support the radiators or heat exchangers that are then bolted on to them. They permit shipping of the transformer without the radiators attached, and also permit removal and replacement of damaged radiators. These units feature O-ring seals on the wafers and mounting faces.

NEEDLE VALVES

Needle valves are used to extract samples of gases from the top of the transformer.

OTHER VALVES

Gate valves are sometimes used in non-critical applications. They are less costly than the more secure globe designs.
