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.
CHM703 High Pressure Control Valve is a high-precision fluid control device specially designed for harsh industrial environments. It is suitable for high-pressure pipeline systems in industries such as petroleum, chemical engineering, power, and metallurgy. This product uses high-quality materials and advanced manufacturing techniques to ensure stable operation even under extreme conditions such as high pressure, high temperature, and strong corrosion. Its compact structure and reliable sealing enable precise regulation of flow and pressure, meeting the strict requirements of complex industrial processes. The high-pressure regulating valve has excellent shock resistance and vibration resistance, and is suitable for frequent opening and closing and high-load operation environments. It is also easy to maintain, effectively reducing long-term usage costs, making it an ideal choice in the field of industrial fluid control.
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.
