● Flow isolation on large pipes can be achieved in 30 seconds to 2 minutes.
● Increases operational uptime and reduces labor costs.
● Operates without special tools; just turn a handwheel and adjust the blind plate to control the pipeline flow. Removes the need for heavy lifting equipment and manual bolt handling.
● Low labor intensity and risk-free operation.
● The device's simple, durable structure ensures easy maintenance.

Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
The DBB Plug Valve is a high-performance fluid control device. It adopts advanced track-guided technology to achieve low-torque opening and closing and zero-leakage sealing. This valve is specially designed for harsh working conditions and is suitable for key fields such as petroleum, chemical industry, power and long-distance pipelines. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations.

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.
