2875 2/2-Way Solenoid Control Valve
Brand: Burkert Fluid Control SystemsThe direct-acting solenoid control valve Type 2875 is used as the regulating unit in control loops.
Due to an elastomeric seat seal the valve closes tight (integrated shut-off function), up to the DN specific nominal pressure, 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.).
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. Optionally the valve can also be driven with DC voltage.
