(Proportional adjustment) DXP series pneumatic thin film straight through single seat regulating valve

DXP type new series pneumatic thin film straight through single seat regulating valve (proportional adjustment)Adopting a top guiding structure and equipped with multiple spring actuators, the flow channel is S-shaped. It has the advantages of compact structure, light weight, sensitive action, low pressure drop loss, large valve capacity, precise flow characteristics, and easy maintenance. Widely used for precise control of gas, liquid and other media, process parameters such as pressure, flow rate, temperature, and liquid level are maintained at given values. Especially suitable for working environments where leakage is allowed to be small and the pressure difference before and after the valve is not significant.

This series of products includes various types such as standard type, heat dissipation type, low-temperature type, adjustable cutting type, corrugated pipe sealing type, jacket insulation type, etc. The nominal pressure rating of the product includes PN (MPa) 1.6, 4.0, 6.4, and 10.0; Valve body diameter range DN (mm) 20~200. Suitable for fluid temperatures ranging from -196 ℃ to+560 ℃ in various grades. The leakage standards include IV level, V level, and VI level; The flow characteristics include straight lines and equal percentages. Multiple varieties and specifications are available for selection.
