Donjoy is specialized in the development of high purity pump, valve controller, automatic regulating valve, aseptic valve, container and process pipeline safety control technology, container and tank cleaning technology, tank and pipeline lighting technology, ASME BPE pipe fittings, sterile pipe fittings, high clean pipe and so on.
High cleanliness pumps are a type of pumps specially designed to transport fluids with extremely high requirements for purity, sterility, and contamination-free in ultra-clean environments. They are widely used in cutting-edge industries with strict standards for contamination control.
valve control unit, it receives from PLC/DCS or other automatic control system instructions to work, at the same time feedback the current valve position signal to PLC/DCS and other automatic control system, but also through the IO-Link, AS-I V3.0 version of the bus communication. Each location will display its current status through a different location color LED light.
valve positioner, it receives from PLC/DCS or other automatic control system instructions such as 4-20mA to work, at the same time feedback the current valve position signal to PLC/DCS and other automatic control system, but also through HART6/7 version of the bus communication.
The actuator is a power device that drives the valve movement. After receiving the control signal (electricity, gas, liquid), it is converted into mechanical force to push the valve stem to open, close or adjust the valve.
The regulating valve is an actuator of the process control system. It can accurately adjust the process parameters such as flow, pressure, temperature, liquid level, etc. of the final medium in the pipeline by dynamically adjusting the valve core opening.
Sanitary valves are designed to prevent pollution and ensure product hygiene and safety, and play a key role in the fields of food, pharmaceuticals, bioengineering, etc.
Valve safety control technology is a key link in the field of industrial automation and process safety, especially in high-risk industries such as petrochemicals, electricity, and pharmaceuticals. It aims to ensure that valves can reliably perform safety functions under normal and abnormal conditions to prevent accidents such as leakage, overpressure, fire, and explosion.
Donjoy cleaning ball products have technical advantages such as lower noise, smaller flow consumption, longer service life, shorter cleaning time, and cleaner cleaning effect.
It is usually a key observation component used in industrial process equipment (such as reactors, storage tanks, pipelines, filters, etc.) to monitor the internal material status (liquid level, color, fluidity, foam, precipitation, reaction progress, etc.) or equipment operation status in real time.
The sealable opening installed on closed equipment or containers such as storage tanks, reactors, boilers, pipelines, etc. Its core function is to provide internal inspection, maintenance, repair, cleaning, etc.
Core purification equipment in industrial processes and fluid systems, intercepting, adsorbing or separating impurities by physical or chemical means to ensure medium purity, protect key equipment, and improve product quality and system reliability
It is the core component of fluid delivery systems in hygiene-sensitive industries such as pharmaceuticals, bioengineering, food and beverages, and cosmetics. It is designed to meet the stringent requirements of aseptic production, easy cleaning, and zero contamination residue.
