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.
C701 Series Single Seated Control Valves are a top-guided single-seat valve. This series of products has absorbed the advantages of similar products at home and abroad and has been improved and innovated. In terms of design, process, and assembly, it has reached the advanced level of similar products domestically and internationally. It has a compact structure, small volume, smooth flow channel, and the fluid passage is in an S-shaped streamline. The flow characteristic curve has high precision, is stable and reliable, and is easy to maintain.
It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
