CONOFLOW HIGH-PRESSURE REGULATOR - HP400 Pressure Reducing - Piston Type
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.

PRINCIPLE OF OPERATION
Turning the control knob clockwise will increase the force on the range spring and,
in turn, the outlet set pressure. Conversely, turning the control knob counterclockwise
will decrease the force on the range spring and decrease the outlet set
pressure. In equilibrium, the force exerted by the range spring is balanced by the
outlet pressure.
An unbalance between the outlet pressure and the set pressure causes a corresponding
reaction in the piston sensor and valve. If the outlet pressure rises above
the set pressure, the piston sensor will lift allowing the main valve to seat. If the
outlet pressure falls below the set pressure, the range spring will push the piston
down and unseat the valve. At equilibrium, the valve plug assumes a position which
supplies the required flow while maintaining the outlet pressure at the set pressure.
