SAMSON 3321-E3 regulating valve process control valve

SAMSON 3321-E3 is an electric regulating process control valve, which is commonly used in industrial process control and can accurately adjust the flow, pressure, temperature and other parameters of the fluid medium. The following is a related introduction:

Working principle: The electric actuator drives the valve core to produce displacement, thereby changing the valve opening to achieve automatic adjustment of the medium flow, temperature or pressure. It can receive signals from the control system (such as 4-20mA current signal) and accurately control the valve opening according to the signal size to meet the process requirements.

Product features: The modular structure is convenient for quick replacement and maintenance, which can effectively shorten the downtime; equipped with a position feedback system, which can feedback the valve opening information in real time, improve the real-time and traceability of the adjustment, and is conducive to precise control and system monitoring.

Application field: With its good performance, the valve is widely used in food, dairy, beverage and other industries. It has passed the EHEDG certification and can meet high hygiene requirements. It is also suitable for HVAC systems in office buildings and smart parks, and can control media such as hot and cold water, steam or air.

Technical parameters: The diameter size is usually available in a variety of options, such as DN15-DN600. The pressure level may cover PN16, PN40, etc. (DIN standard) or 125 to 300 (ANSI standard). Key components may be made of aviation-grade aluminum alloy (tensile strength ≥300MPa) with good sealing performance. Laboratory tests show that the switch life can reach tens of thousands of times.
