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.
