2 2861 2/2-Way Solenoid Control Valve Made for custom engineered applications DN mm 1/8, sub-base or custom engineered armature 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 (see datasheet). 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. Please follow the instructions for a customised design on page 5 of this datasheet. Circuit function direct acting 2-way solenoid control valve, normally closed P Valve control takes place through a PWM signal 1). 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.

Due to an elastomeric seat seal the valve closes tight (integrated shut-off function), up to the DN specific nominal pressure, see ordering chart on page 3. The plunger of the valve is assembled frictionless, which leads to an extraordinary adjustment characteristic. This valve is particularly suitable for demanding control tasks (high control range, dry gases, etc.). Circuit function 2 () 1 (P) Direct-acting, 2-way solenoid control valve, normally closed Valve control takes place through a PWM signal 1).

46 8605 Control Electronics for Solenoid Control Valves Microprocessor-controlled electronics Selectable input signal djustable PWM frequency Optional RS232 or RS485 interface Type 8605 can be combined with... Type 8605 with operating unit combined with type 2873 Type 8605 without operating unit combined with type 2873 The digital control electronics, type 8605, serves to operate valves in the power range from m. The electronics converts an external standard signal into a pulse-width modulated (PWM) signal with which the opening of the valve and hence a fluidic output parameter (e.g. flow rate) can be infinitely varied. n internal current control with the duty cycle factor of the PWM signal as control variable ensures that every value of the input signal, irrespective of the thermal condition of the coil, is unambi guously assigned a given value of the effective coil current. Compared to DC operation of solenoid control valves the PWM operation improves, among others, their sensitivity and hysteresis. display and operating keys allow the electronics to be easily adapted to a particular solenoid control valve and to the concrete conditions of an application.

It is compatible and tested with all Bürkert proportional valves and sensors and can be connected with every none-bürkert Control valve by standard signal ( m, or PWMoutput). The proportional & Integral (PI) process controller is equipped with many additional functions. The process value feedback can be supplied as one of three analog inputs; a standard signal ( m/0...10v), frequency or Pt100 signal; directly to the universal controller. The process switching points can be set via a m or signal or with the keypad. For temperature specific control, it is possible to set a cascade structure with both temperature and flow as inputs. Thanks to the proportional control capabilities, a wide range of control functions can be performed in a variety of liquids and gas medias.
