Q & A
HPH High Pressure Regulator Q & A
+What is the HPH regulator and what is it used for?
The HPH (High Pressure Hydraulic/Pressure Reducing Regulator) is a stainless-steel, high-pressure control valve designed to reduce a high inlet pressure to a desired outlet pressure in hydraulic or pneumatic systems. According to the manufacturer, it is suitable for inlet and outlet pressures up to 10,000 psig (≈ 690 bar).
+What pressure ranges are available for the outlet (reduced) pressure?
The HPH series offers six pressure ranges for outlet pressure: 0-500 psig (0-34.5 bar), 0-1000 psig (0-69?bar), 0-1500 psig (0-103?bar), 0-3000 psig (0-207?bar), 0-5000 psig (0-345?bar), and 0-10000 psig (0-690?bar).
+What media (fluid/gas) is it compatible with?
The HPH is designed for both hydraulic and pneumatic (gas) applications at high pressures. The stainless steel body, corrosion-resistant seat, and ceramic valve ball make it suitable for harsh environments.
+How is maintenance handled? What features help serviceability?
The HPH has a cartridge-style service insert, meaning the main valve and filter assembly can be replaced in-line (without removing the regulator body from the piping) to reduce downtime. Also, the supply filter protects against contamination; the robust materials (MP35N seat, ceramic valve) promote long life. For maintenance: ensure periodic inspection of filter, check for seal wear, internal contamination, proper adjustment of spring/range, and test for leakage.
+What media can the HPH regulator handle?
The HPH is compatible with both gases and hydraulic fluids and is built to operate reliably in harsh, corrosive, and high-pressure environments. Its stainless-steel body and corrosion-resistant internal components allow it to handle demanding media, although exact compatibility depends on the fluid chemistry and seal material chosen.
