OVERFLOW VALVE | R 101 U
Design and function
The R 101 U is a gas overpressure valve that opens from a set pressure.The diaphragm is charged from below through the impulse line (Ø8mm). When the pressure under the diaphragm becomes higher than the spring pressure, the valve will open, allowing the medium to escape. Since there is only spring load, the valve can be installed in any position.
