No, calibration is not possible for these devices.
The membrane-operated pressure reducing valve is frequently used in applications with low to normal back pressure. Due to the membrane, it also delivers more sensitive regulation.
The piston-operated pressure reducing valve is frequently used with high back pressures and aggressive media. It has an extremely robust design, giving it a high level of safety in case of pressure surges.
Direct acting normally closed solenoid valves actuate the magnet armature with a sealing element directly via the solenoid (they do not need minimum or differential pressure). The valve is sealed by the existing operating pressure, or at low pressure with an additional compression spring (the spring force must be great enough to securely close the valve at an operating pressure of 0 bar). When voltage is applied to the solenoid, the magnet armature is tightened and the valve opens. In doing so, the force of the operating pressure and the closing spring must be overcome.
