Types 95LD and 95HD
2
Types 95LD and 95HD are small-size, large-
capacity, differential pressure regulators. They are
suitable for steam, air, gas, oil, water, and other uids
control. Typical applications include use on testing
xtures, wash tanks, sterilizers, steam tables,
fuel lines, and plant air supplies. The differential
pressure range of the Type 95LD regulator is from
2 to 30 psi (0,14 to 2,1 bar) (three spring ranges). The
Type 95HD differential pressure range is from
5 to 150 psi (0,34 to 10,3 bar) (seven spring ranges).
The Specications section gives some general
specications for the 95 Series differential pressure
regulators. The nameplates give detailed information
for a particular regulator as it comes from the factory.
