SAMSON 3730-2 is a digital electric valve positioner for pneumatic control valves with a microprocessor and adjustable output pressure. The following is a detailed introduction:
Input signal: supports 4-20mA (two-wire system, with reverse protection), minimum range 4mA, static damage limit 100mA.
Gas source pressure: supply pressure ≤10bar, output pressure range 0.2-7bar, meeting the needs of most pneumatic valves.
Environmental adaptability: working temperature is -20℃-80℃, protection level IP66, suitable for conventional industrial environments.
Mechanical compatibility: adapt to rod-type brackets that comply with IEC 60534-6-1 standard or angular stroke actuators that comply with VDI/VDE 3845 standard, and can be used for linear or angular stroke valves.
Functional features: preset travel range (such as 3.6-200mm) through DIP switch, without complex software configuration. Can be directly installed on SAMSON control valve actuators to reduce additional bracket costs. The built-in microprocessor ensures high accuracy of valve opening adjustment, with a final deviation of ≤1%.
Application scenarios: Suitable for low-complexity valve adjustment in water treatment and HVAC systems. It can also be used for traditional system transformation to replace old analog positioners and retain the original 4-20mA signal link.
SAMSON 3730-2 series digital electrical valve positioners have a variety of specific models, the following are some of them:
3730-200010.00: This is a model in the 3730-2 series. It has the basic characteristics of this series of digital electrical valve positioners and can accept 4-20mA input signals for controlling the valve position of pneumatic control valves.
3730-210010: This model has a position feedback function, which can better feedback the valve position information to the control system, facilitate real-time monitoring of the valve status, and is suitable for occasions with high requirements for valve position monitoring.
3730-2 Rated stroke: 3.6-200mm: This model specifies a rated stroke range of 3.6-200mm, which can be applied to pneumatic valves with different stroke requirements and can be adapted and debugged according to specific valve stroke requirements.
