HPE – Hydro Power Equipment

Mining pipeline and underground pump column valves and fittings

Upwey Group is the Australian agent for the HPE range of valves and couplings for use in high pressure mining pipelines and underground pipe column systems.

HPE’s column surge protection system protects against pump motor trip outs and minimizes pressure surges and water hammer in pipelines. All necessary protection is allowed for and a column drain valve is usually incorporated to drain the column should maintenance or repair work be required.

Safety Isolation Valve (High and Low Pressure): (View Safety Isolation Valve PDF [186 kb])

Incorporates both excess flow shutdown and tight shut-off isolation functions. In the event of an excess flow condition arising, example from a pipe burst, the valve will close automatically. To avoid pressure surges (ie. water hammer), the valve closes in two stages: initially very rapidly to prevent runaway flow, then finally slowly to give a soft shut off. Safe filling, flushing and isolation of pipelines are guaranteed, whether the valve is operated manually or by an actuating cylinder.

Pressure Reducing Valves (High and Low Pressure)

Pressure Regulating, Internal and External Ratio Valves, as well as Multi-Stage Ratio Valves available for varying ratios from as low as 1.2: 1 up to 20:1 using a steel body (maximum rating of 25MPA) with finite pressure adjustment control to suit your individual requirements.

Energy Dissipator: (View Energy Dissipator PDF)

Reduces upstream pressure to a predetermined downstream pressure at a constant nominated flow rate by directing the flow through a row of engineered perforated plates mounted within a cylindrical housing.

The safe, easy and economical way of joining high pressure pipes compared with traditional flanges.

Backfill/Mud Diverter Valve : (View Backfill/Mud Diverter Valve PDF [168 kb])

Diverts the flow of backfill material from one point of placement to another as well as diverting flush water away from the placement point when pipes are flushed at the end of a backfill placement cycle. This ensures that the placed backfill material is not diluted or washed away by the flush water.
