● 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 Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The Power Plant Check Valve has small fluid resistance, the medium channel inside the valve body is straight through, and the flow direction of the medium does not change when it flows through the check valve. The pressure self-tightening seal is used, and the two ends of the valve are usually welded. The valve flap closes quickly, the water hammer pressure is small, the body structure is simple, the production process is good, the sealing performance is good, and the sealing surface is less eroded when fully opened. A wide range of applications.
Y-Type Check Valveis a type of valve used to prevent fluid backflow, named after its Y-shaped valve body. It allows fluid to flow in one direction, and when the fluid flows in the opposite direction, the valve automatically closes to prevent backflow.
