98 Series Relief Valve or Backpressure Regulator

98 Series is used for backpressure or relief applications in liquid, gas, air, and steam service. Types 98L, 98H, and 98HH are direct-operated and spring-loaded. Types 98LD and 98HD use additional pressure loading to maintain relief differential pressures, backpressures or for remote setpoint adjustment.

Type 98HM is a direct-operated, spring to close regulator for backpressure or relief applications in liquid, gas, or steam service. The regulator requires no external power to operate and features a sensing line connection for sensing pressure externally from the regulator. A seal washer for the set screw can be included when applications require pressure loading of the spring case (not available on NPS 1-1/2 and 2 bodies / DN 40 and 50).
