RAYS single driving double ball valve is a special ball valve design, which combines two ball valves together, but is operated by only one drive device. This design is usually used in situations where two parallel pipelines need to be controlled or isolated at the same time. The design and application of single drive double ball valves need to consider specific process requirements and operating conditions to ensure its long-term stable operation and system safety.
RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
RAYS cryogenic ball valve with extended bonnet ball valve will bring you a huge gain in the field of cryogenic LNG service. Service temperature from -51° to -196°C (-59,8° to -320,8°F) with extended bonnet design.
