●The valve features two parallel gate plates and a wedging device, updating the traditional single gate plate design.
●Sealing elements are designed as separate components, which prevents deformation from thermal expansion and temperature differences, ensuring a reliable seal.
●The materials used for the sealing components are resistant to wear and corrosion, enhancing the valve's longevity.
●It is equipped with a bidirectional forced sealing capability, which simplifies operations and ensures a dependable seal.
●The fully enclosed design of the valve provides excellent protection, allowing for operation in all weather conditions.

The Sampling Double Disc Gate Valve is an efficient valve specifically designed for industrial sampling. It features a double-gate structure that ensures reliable sealing and precise sampling control. The unique double-gate design guarantees stable media flow during the sampling process while effectively preventing leakage and contamination. This valve is widely used in industries such as chemical and pharmaceutical, especially for sampling inspections in reactors under crystallization conditions.
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.
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.
