● Dual Sealing Structure: Equipped with a double-gate design, each gate features an independent sealing system to completely isolate the medium during sampling, eliminating the risk of leakage.
● Bidirectional Sealing Function: The valve provides sealing in both forward and reverse directions, effectively preventing backflow of the medium and ensuring the accuracy and safety of sampling.
● High Corrosion Resistance: The valve body and key components are made of high-quality corrosion-resistant materials, suitable for various acidic and alkaline media environments, extending service life.
● Easy Operation: Available with manual or electric actuation, the valve offers flexible operation and can quickly complete sampling tasks, improving work efficiency.
● Precise Sampling: The valve design ensures stable sampling flow, avoiding media fluctuations and meeting high-precision sampling requirements.
● Convenient Maintenance: With a compact structure that is easy to disassemble and maintain, it reduces maintenance costs and downtime.
● The Double Gate Sampling Valve is widely used in industries such as chemical, pharmaceutical, and food, making it an ideal choice for safe and efficient sampling.

The quality of forged steel parts is higher than that of cast steel parts, and they can withstand the impact of beatings. The plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of cast steel gate valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel gate valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and the sealing performance is much better than that of cast steel gate valves, and the service life is longer. The flow direction of the medium is not restricted like other gate valves.
The Axial Flow Check Valve has a unique axial flow design, and its spool is aligned with the flow direction, significantly reducing the resistance loss when the fluid passes through. The spool is driven by spring or fluid pressure for quick opening and closing. When the fluid is flowing forward, the spool is pushed open and the fluid passes smoothly. When the fluid flows in reverse, the spool is quickly closed, effectively preventing backflow, and ensuring the stability and safety of the system operation.
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.
