HP700 High Pressure Two-Stage Regulator

Brand: ITT Conoflow

Conoflows HP700 Series regulator is a two-stage, high purity unit designed to provide constant outlet pressure regardless of inlet pressure fluctuations.

This unit is available in either Brass or Stainless Steel construction. Maximum supply pressure rating for either material is 3500 psiG (24.2 MPa).

To provide optimum performance in specific applications, this unit is offered with relieving, non-relieving, and tied (non-relieving) diaphragm options.

Typical applications for the HP700 regulator are gas chromatography, calibration systems, cylinder gases, and precise regulation of corrosive and non-corrosive media.

Adjustment within each of five available ranges is made with a standard large handwheel.

A wrench style knob with a locking device and a “T” bar handle are available as optional adjustments.

This unit is supplied with ¼” inlet and outlet connections. Inlet and outlet gauge ports (¼” NPT) are standard.

High purity internal connections and VCR, Vacuseal and Ultra Seal welded fittings are optional.

Captured bonnets for both stages are standard. This regulator is designed for reliability with an absolute minimum of maintenance.

The characteristics are a result of Conoflow’s high standards of manufacturing and years of experience as a leading manufacturer of pneumatic instrumentation.
