Starline - Floating Valves
Starline ball valves are manufactured as 3 PIECES BOLTED CONSTRUCTION. This allows easy maintenance in line due to the possibility of “swing-out” of the center section, permits a flexibility in production due to the unlimited combinations of possible end connections and asymmetric construction. Not to count the possibilities of any distributor to change quickly the configuration of the valve available in stock to serve any market request.
In consideration of the market requirements, Starline has also developed a line of 2 PIECES BOLTED CONSTRUCTION valves to cover flanged valves ASME CLASS
150/300 and DIN class PN 10/16/40. The same construction has been developed for the CRYOGENIC SERVICE and METAL SEATED HIGH TEMPERATURE.
- Blow-out proof stem construction
- Antistatic design
- Triple stem sealing
Technologically advanced seat design allows easy interchangeability and upgraded performance to the same valve. All seats can be supplied in standard or encapsulated design, which permits to the same seat material higher resistance to pressure and temperature.
All Starline valves are bidirectional. A pressure-balancing hole is helping the pressure to be equalized throughout the body cavity and guarantees a better performance to the valve. Starline seat design also allows automatic body cavity relief due to a special machining of the seat. Nevertheless for quick expanding gases or other media (chlorine – oxygen..) Starline recommends the use of a supplementary venting hole in the ball (upstream side – unidirectional valves).
