Section 1: Imported Pneumatic High-Temperature Control Valve Product Overview
Germany's VardWODEImported pneumatic high-temperature regulating valves, consisting of a multi-spring pneumatic diaphragm actuator and a low-flow resistance high-temperature regulating valve body. The multi-spring actuator features a low height, light weight, and simple installation. The flow channel of the pneumatic high-temperature regulating valve body isSStreamlined, featuring compact structure, light weight, quick operation, low pressure drop loss, large valve capacity, high accuracy in flow characteristics, and easy maintenance, suitable for severe working conditions. Air-operated diaphragm high-temperature control valve with electrical-Air valve positioner or pneumatic valve positioner, capable of automatically adjusting and controlling fluid media in process pipelines. Pneumatic high-temperature regulating valves are mainly used to maintain process parameters such as pressure, flow rate, temperature, and liquid level of gases, liquids, steam, etc., at specified values.
Imported pneumatic high-temperature regulating valves are suitable for applications that allow low leakage, small pressure difference before and after the valve, and high temperatures.
