HV Series Loading Valve HV800-S-N-6 | FT9094-1

Ask A Question

Description & Features

The HV800-S-N-6 belongs to WEBTEC's HV Series of loading valves, designed to deliver smooth, controlled pressure regulation in both flow directions across demanding hydraulic test and measurement applications. With a maximum operating pressure of 420 bar (6000 psi) and a flow capacity of 800 L/min (210 US gpm), it is suited to high-flow circuits where stable load simulation is required.

The aluminium body and steel internals keep weight to a practical 5 kg (11 lbs) while maintaining structural integrity under sustained pressure. FKM seals provide reliable compatibility with mineral oils to ISO 11158, and the valve operates across a fluid temperature range of 0 to 120 °C (32 to 248 °F). The 1-7/8" -12UN #24 SAE ORB porting makes integration with standard hydraulic test rigs straightforward. Ambient service conditions are rated from 5 to 40 °C (59 to 104 °F).

Question by: Carol B on Jan 6, 2026, 12:04 PM
what's the max pressure this valve handles, and is 420 bar pretty typical for a loading valve in this size range?
Answer by: Customer Support on Jan 7, 2026, 6:18 PM
For a valve rated to handle flows up to 800 L/min, 420 bar (6000 psi) is a solid ceiling. That puts it well within range for demanding hydraulic test bench work where you need reliable backpressure control across both flow directions. The aluminum body keeps weight down at 5 kg, but the steel internals handle the pressure load where it counts.
Question by: Brent W on Jun 25, 2025, 12:43 PM
How much flow can the HV800-S-N-6 handle at its maximum capacity?
Answer by: Customer Support on Jun 27, 2025, 8:13 AM
At full capacity, the HV800-S-N-6 can manage a flow of up to 800 liters per minute, or 210 US gallons per minute.
