Design and function
The spring-loaded gas pressure regulator R 51 has the function of keeping the outlet pressure of a gaseous medium constant within allowable limit values, independently of the effect of interferences, such as changes in the inlet pressure and/or in the gas tap, in the connected regulating line on the outlet side. The gas pressure regulator is composed of the actuator housing and the „diaphragm assembly plus actuator“ functional unit. The valve seat model is pre-pressure-compensated. The gas flows through the actuator housing in the direction of the arrow. The internal or external measuring line connection is used to pass the outlet pressure to be regulated to the bottom of the diaphragm comparator of the diaphragm assembly. It compares the actual value with the command variable preset by the force of the setpoint spring. The setpoint required in each case is set via the setting screw. Any deviation from the setpoint is transmitted by the valve stem to the actuator, which is adjusted such that the actual value is adjusted to the setpoint. In case of zero tap, the actuator will close tight, causing the closing pressure to be established.
