Application
D22pressure reducing valves protect installations against
excessivepressure from the supply. They canbeused for
industrial or commercial applicationswithin the rangeof their
specification. Becausepressure reducing valves are subject
towear, they cannot beusedas theonlymeans of protection
and if thedownstream systemneeds tobeprotectedagainst
excessivepressure toprevent leakage, thena suitable safety
valvemust be fitted.
