The SAMSON 3701 Series is a compact and reliable direct-operated solenoid valve designed for precise control of pneumatic actuators. It serves as a key accessory for automated control valves, responsible for converting electrical signals from the control system (DCS or PLC) into pneumatic actions to drive valve operation.
This versatile 3/2-way solenoid valve is engineered for broad compatibility. It can be installed on linear actuators conforming to the NAMUR standard (IEC 60534-6) or on rotary actuators with a NAMUR interface according to VDI/VDE 3845. Its robust design, featuring a reliable diaphragm actuator system with a baffle/nozzle assembly and a booster valve, ensures high operational reliability in demanding industrial environments. The 3701 is particularly suited for applications requiring safety and efficiency, offering features like low power consumption and suitability for safety instrumented systems.
Key Features and Benefits:
Direct-Operated and Compact Design: Ensures reliable switching and saves space in control cabinets or on valve assemblies.
Universal Mounting: Easy installation on both linear (IEC 60534-6) and rotary (VDI/VDE 3845 NAMUR) actuators, offering great flexibility.
High Reliability: The internal design with a baffle/nozzle assembly and booster valve provides consistent performance.
Safety Compliant: Models are available with ATEX certification and are suitable for use in intrinsically safe applications. The valve is also certified for Safety Instrumented Systems (SIL) per IEC 61508.
Low Power Consumption: Designed for energy-efficient operation, compatible with binary control signals from automation systems.
