2861 2/2-Way Solenoid Control Valve
Brand: Burkert Fluid Control Systems
Type 2861 is an extremely compact solenoid control valve and is available with an orifice up to 2 mm. It is based on the standard version of Type 2871. It is used as an actuator in closed control loops (pressure, flow, temperature, etc.).
Compared with the standard version, the valve is essentially of simpler construction and assembly and testing procedures are optimized, easing high volume series production with shorter delivery times.
Valve control takes place through a PWM signal. The duty cycle of the PWM signal determines the coil current and hence the position of the plunger.
The Burkert control electronics Type 8605 converts an Analog signal to a reference value corresponding to the valve type PWM signal and provides additional functions such as temperature compensation (coil heating), ramp function and the adjustment of minimum and maximum duty cycle/coil current for the control range.
