5 2863 2/2-Way Solenoid Control Valve Made for custom engineered applications DN mm 1/8", 1/4 sub-base or custom engineered armature Type 2863 is an extremely compact solenoid control valve and is available with an orifice up to 4mm. It is based on the standard version of Type 2873 (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 A A P direct acting 2-way solenoid control valve, normally closed 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.

However, a sufficient part of the pressure drop should be taken across the valve even when it is fully opened.

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 A 2 (A) 1 (P) Direct-acting, 2-way solenoid control valve, normally closed 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. Optionally the valve can also be driven with DC voltage.

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, the characteristics may change.
