Using with steam The valves can be used for low-pressure steam up to 115 °C with the same ∆pmax values. When us- ing the valve, make sure that it does not operate mainly on the lower third of its stroke range. This leads to an extremely high flow speed, which greatly reduces the serviceable life of the valve.Right of amendment reserved © 2015 Fr.
