Three-Piece Ball Valves


Three-piece, stainless steel ball valves are now available for use with Viega ProPress® stainless steel systems. The three-piece stainless steel ball valve, the latest innovation in the Viega ProPress stainless steel product offering, features new three-piece construction from high-quality, 316-grade stainless steel. The three-piece stainless steel ball valves are available in sizes 1/2" to 2" and have a machined ISO 5211 mounting pad for actuators or operators. The ball within the valve is a full port ball and the handle locks in two positions. The press ends of the valve include the FKM sealing element for higher temperature tolerance as well as the patented Smart Connect® feature. 

 “This three-piece ball valve is a valuable addition to Viega’s ProPress stainless steel line,” said Christoph Volkmer, associate product director, Viega. “One of the exciting features of Viega’s new ProPress stainless three-piece ball valve is that it can be maintained without being removed.” The high-quality stainless steel balls and stems make these valves ideal for a wide variety of industrial projects. Repair kits for the valves are available separately from Viega. Available in two high-quality stainless steel grades, 304 and 316, and with more than 600 fitting configurations, Viega ProPress stainless steel is ideal for industrial and commercial installations in applications such as food and beverage processing, chemical processing, pharmaceutical and biotech processing, oil and gas, mining and manufacturing. 

The Viega ProPress system can be installed wet or dry, making it ideal for maintenance or emergency repair jobs, reducing costly downtime by decreasing plant shutdowns. It can also be adapted to any existing piping system with adapters and flanges. The patented Smart Connect feature, available only from Viega, provides a quick and easy way for installers to identify connections that need pressing, so that they are not missed.
