Type description
Type 2863 is an extremely compact solenoid control valve and is available with an orifice up to 4 mm. It is based on the standard version of Type 2873.
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.

6.2. Exemplary characteristic curve of a proportional valve
Note:
In continuous flow applications, the choice of an appropriate valve size is much more important than with on/off valves. The optimum size should be selected such that the resulting flow in the system is not unnecessarily reduced by the valve. However, a sufficient part of the pressure drop should be taken across the valve even when it is fully opened.
Recommended value: Δp valve
> 25 % of total pressure drop within the system
Otherwise, the ideal, linear valve curve characteristic is changed.
If the differential pressure (difference between inlet and outlet pressure) exceeds half the value of the nominal pressure discontinuities may occur.
For that reason take advantage of Bürkert competent engineering services during the planning phase!

7. Product operation
7.1. Control unit
Valve control takes place through a PWM signal (pulse-width modulation). 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 data sheet Type 8605 ) converts an analogue signal to a reference value cor responding 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.
Please note the sizing comments for such a control valve in chapter “6.2. Exemplary characteristic curve of a proportional valve” on page 8
.
