SAMSON 3321-PP regulating valve process control valve

SAMSON 3321-PP is a control valve for process control, where "PP" may represent certain material characteristics or specific configurations of the valve, and is often used in occasions that require corrosion resistance. The following is a related introduction:

Working principle: Similar to general electric control valves, SAMSON 3321 - PP drives the valve core to produce displacement through an electric actuator, changes the flow area between the valve core and the valve seat, thereby adjusting the medium flow and realizing the control of process parameters such as pressure and temperature. It can receive 4-20mA current signals or 0-10V voltage signals, etc., and accurately control the valve opening according to the signal size.

Product features:

Good corrosion resistance: Due to the use of PP-related materials (possibly corrosion-resistant materials such as polypropylene), it has good corrosion resistance and is suitable for process flows that transport corrosive media such as acids and alkalis. It can work stably in environments with corrosive media such as chemicals and pharmaceuticals.

High-precision adjustment: Equipped with a high-precision positioner, it can achieve precise flow regulation, and the control accuracy can reach about ±0.3%, meeting various precision control needs.

Intelligent communication function: HART protocol interface may be integrated to facilitate communication with the control system, realize remote monitoring and parameter setting, and facilitate operators to grasp the valve status in real time and perform remote operation.

Application areas:

Chemical industry: Applicable to the transportation and control of various chemical raw materials and products, such as acid and alkali solution transportation, chemical agent addition, etc., which can effectively resist medium corrosion and ensure long-term stable operation of the system.

Pharmaceutical industry: In the pharmaceutical process, it can be used for the transportation and flow control of corrosive liquids, etc., which meets the strict requirements of the pharmaceutical industry for hygiene and corrosion resistance.

Food and beverage industry: For some acidic or alkaline food raw material processing processes, such as juice preparation and sauce production, the valve can rely on its corrosion resistance and high-precision adjustment capabilities to ensure precise control of the production process and food safety.

Technical parameters:

Diameter range: Usually a variety of diameter options are provided, which may cover different sizes such as DN15-DN600 to adapt to pipeline systems with different pipe diameters.

Pressure level: The pressure range may vary depending on the specific model, and generally can meet the pressure level requirements of PN10 - PN420, or correspond to ANSI 150LB - 2500LB and other standards.

Temperature range: According to the material and structural design, it can adapt to a certain temperature range, such as - 20℃ - 120℃. The specific temperature range needs to refer to the product manual.

Flow characteristics: There are a variety of flow characteristics such as equal percentage and linearity to choose from. Users can configure according to actual process requirements to achieve ideal flow regulation effects.
