BURKERT TYPE 2861 - Direct-acting 2-way basic proportional valve

Proportional valve (PWM Valve) type 2836, 2861, 2863, 2865, 2871, 2873, 2875, 6024 ซึ่งใช้ร่วมกับ Type 8605 ซึ่งเป็นอิเลคโทรนิคคอนโทรลยูนิต ซึ่งทำหน้าที่ Convert สัญญาณ Analog เป็นสัญญาณ PWM

Type 2861 is an extremely compact solenoid control valve and is available with an orifice up to 2mm. 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.

  • High dynamics
  • Orifice sizes DN 0.8 ... 2.0 mm
  • Good range

 

Circuit function A

 2/2 way direct-acting, solenoid proportional control valve

Valve control takes place through the control electronics of Type 8605, which converts an analogue input signal into a PWM) (pulsewidth modulation) signal.

Valve control takes place through a PWM signal1). The duty cycle of the PWM signal determines the coil current and hence the position of the plunger.

The Bürkert control electronics Type 8605 (see relevant datasheet) 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 min. and max. duty cycle/coil current for the control range.
