Special-purpose regulating valves for Corrosion resistance and power of Azbil VDD/VNP/HIT have the following features:
Local user interface with LCD and button mode for use in the explosive environment on the front of the machine. From this interface, an automatic adjustment program (automatic setting), machine and equipment confirmation, and various variables display can be performed. Special-purpose regulating valves for Corrosion resistance and power of Azbil VDD/VNP/HIT can be integrated with the machine management system. There is a control valve diagnostic algorithm function block with information obtained and processed according to the supply air pressure, output air pressure 1, output air pressure 2, built-in pressure sensor to detect the backpressure of the nozzle.

Products can be provided to meet a variety of body material specifications, such as carbon steel, which is generally used with water, steam, and fuel oil; highly corrosion-resistant stainless steel, which is essential for controlling corrosive fluids; and resin. A bellows seal can be added to valve stems. Increasingly sought-after specifications for gland packings can be applied to comply with fugitive emissions regulations for volatile organic compounds. Control of various fluids is enabled by hardening of the valve interior, self-washing structure (optional), and steam jacketing (optional) to prevent coagulation by keeping the valve body hot.
