SAMSON 3321-E1 regulating valve process control valve

SAMSON 3321-E1 is an electric regulating process control valve with modular structure, high regulation accuracy and strong adaptability. It is widely used in food, pharmaceutical, petrochemical and other industries. The following is a detailed introduction:

Working principle: Similar to other electric regulating valves, SAMSON 3321 - E1 drives the valve core to produce displacement through an electric actuator, thereby changing the valve opening. It can receive signals from the control system (such as 4 - 20mA current signal or 0 - 10V voltage signal, etc.), accurately control the valve opening according to the signal size, and realize automatic adjustment of parameters such as medium flow, pressure or temperature.

Product features:

Modular design: easy to replace and maintain quickly, which can effectively shorten downtime, reduce maintenance costs and improve equipment operation efficiency.

High-precision adjustment: Some models are equipped with intelligent positioners, which can achieve a control accuracy of ±0.3%, which can accurately meet the requirements of parameter control in various process processes.

Good communication capability: The product integrates the Internet of Things communication module, supports Modbus, HART and other protocols, can be seamlessly connected with the industrial control system, adapts to the intelligent needs of Industry 4.0, and is convenient for remote monitoring and operation.

Excellent material: The key components are made of aviation-grade aluminum alloy (tensile strength ≥ 300MPa), and have undergone 12 corrosion resistance tests. The sealing materials have passed multiple certifications. Laboratory tests show that the switch life exceeds tens of thousands of times and can work stably under various complex working conditions.

Application areas:

Food and beverage industry: It has passed EHEDG certification and meets food hygiene standards. It can be used for steam heating, cooling water distribution, CIP cleaning system, liquid proportioning and other links to ensure the precise control and hygienic safety of the food production process.

Pharmaceutical industry: It can meet the strict requirements of pharmaceutical processes for high-precision control and sanitary conditions, and is used in process flows such as liquid drug delivery, temperature and pressure control.

Petrochemical industry: With its corrosion resistance and high reliability, it can be used for various fluid medium control in petrochemical production, such as oil product delivery and chemical raw material metering.

Technical parameters:

Diameter size: DN15 - DN600 full-diameter selection is available to meet the needs of different pipe diameter systems.

Pressure range: It can withstand higher pressures, and some models can reach 2500 pounds of pressure. The specific pressure levels may be PN10 - PN420, etc., or correspond to ANSI 150LB - 2500LB and other standards.

Temperature range: According to the different valve cover designs and materials, it can adapt to different temperature conditions. Generally, there are normal temperature types (-29℃ - 250℃), high temperature types (-29℃ - 450℃) and other options.

Flow characteristics: It usually has equal percentage, linear and other flow characteristics, which can be selected according to specific process requirements to achieve precise flow regulation.
