FACTS I FIGURES I DATA . Pressure retaining valve V 186 V86

The pressure retaining valve V 186 are used where a constant back pressure is required for operating process. Installed as bypass, it can also be used as a relief valve for reducing pressure peaks. The cavity free valve body design, without gasket, makes it particularly suitable for high purity applications and aggressive fluids. The pressure retaining valves are used to provide a constant back pressure in process plant. If the inlet pressure rises above a preset value, the diaphragm is raised against the spring force. The valve opens and the excess pressure escape into the outlet line. If the...
