HP400 Self-Contained Regulator

self-contained regulator, economical regulator
Conoflow's HP400 is a piston-sensing, self-contained pressure reducing regulator. High inlet and outlet pressures allow use of this regulator in component testing, calibration systems, manufacturing processes and other applications that require an economical regulator having reliable and safe operating characteristics.

The brass constructed HP400 Regulator has a maximum supply pressure rating of 3500 PSIG (24.2 MPa). Control setting range for this unit is 20 to 2500 PSIG (0.138 -17.25 MPa). Adjustments within the range are made with a large handwheel furnished with the standard unit. Optional adjustment devices include a wrench style knob with a locking device or a "T" bar handle.

This unit is supplied with 1/4" NPT inlet and outlet connections. Inlet and outlet gauge ports (1/4" NPT) are standard. The regulator is non-relieving with a captured bonnet.
