● 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.

It is mainly used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc. to transport high viscosity media that solidify at room temperature. The insulation jacket of BJ45W DC jacket insulation globe valve is welded between the two flanges of the valve, and there are two connection ports for the insulation jacket on the side and bottom of the valve. DC insulation globe valve is particularly suitable for pipelines in the chemical and fertilizer industries, and the inclusion of steam in the jacket can prevent the crystallization of the medium. Insulated globe valves are widely used in various systems such as petroleum, chemical, metallurgical, pharmaceutical, etc.
The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop 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 their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
The Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
