gets pretty cold out in the winter time in the shop. what is the lowest temp this thing is rated to run at?

Answer by: Customer Support on Dec 9, 2025, 8:44 AM

Operating in freezing environments is absolutely fine down to -13 degrees Fahrenheit. You just need to make sure your fluid viscosity stays within the allowable cold start limit of 9000 SSU at those lower temperatures.

i’ve got an HE2000 power unit and the relief is acting up. is this the right relief valve for that series, or is it some oddball part

Answer by: Customer Support on May 21, 2025, 6:01 PM

For HE2000 Series power units, this is the cartridge style relief valve used in that family of units, with an adjustable relief range of 1500 to 2500 PSI. It’s intended for repairing or modifying existing HE2000 units, and it’s also used when building custom HE2000 Series power units.

Question by: Johnny K on Feb 9, 2026, 7:20 PM

pressure range on this relief valve -- is 1500 to 2500 psi the full adjustable range or just where it ships set from the factory?

Answer by: Customer Support on Feb 11, 2026, 5:46 PM

That 1500 to 2500 psi is the adjustable range for the valve, not a fixed factory setting. You can dial it in anywhere within that window to match what your HE2000 power unit needs. The cartridge-style design on these is built for dependability and long service life, so once you get it set where you want it, it holds up well under repeated cycling.
