Ask A Question

Description & Features

Part of the 180 Series, the WEBTEC 185-E1F-B rotary shear directional control valve is designed for high-pressure hydraulic directional control where minimal internal leakage is a priority. It handles flows up to 26.5 L/min (7 US gpm) at pressures reaching 350 bar (5000 psi), making it well suited to demanding mobile and industrial hydraulic systems.

The valve is constructed with an aluminium body and carbon steel internals, fitted with NBR seals and a phenolic resin knob. Connections are 3/8" NPTF, and the unit accepts mineral oils conforming to ISO 11158, with other fluid compatibility available on request. A fluid temperature range of -30 to 120°C (-22 to 248°F) and an ambient rating of -20 to 50°C (-4 to 122°F) support year-round outdoor and workshop service. Net weight is 1.3 kg (2.9 lbs).

Question by: Greg E on Jan 21, 2026, 11:29 AM
Is the 185-E1F-B valve compatible with any type of hydraulic fluid?
Answer by: Customer Support on Jan 22, 2026, 1:22 PM
The 185-E1F-B valve is primarily compatible with mineral oils conforming to ISO 11158 standards. If you need it to work with other fluids, it's best to check with the manufacturer for specific fluid compatibility.

what's the max pressure this valve handles? running a system at 4800 psi and need to know if theres any headroom
Answer by: Customer Support on Jun 27, 2025, 7:20 AM
At 4800 psi you've got room to spare. The 185-E1F-B is rated to 350 bar, which works out to 5000 psi. That puts you about 200 psi under the ceiling, so you're in a workable range for steady operation.
