95H Series Pressure Reducing Regulators
B
Introduction
The 95H Series regulators are compact,rugged, direct-operated, pressure reducing regulators. The units are available in 1/4
through 2-inch (DN 8 through 50) body sizes and are offered with several different end
connection styles. They are designed to handle inlet pressures up to 600 psig (41,4 bar) and temperatures up to 650°F (343°C).
The Type 95HD differential pressure reducing regulator uses spring force to maintain a pressure differential between the spring case loading pressure and the regulator outlet pressure.
