Ask A Question

Description & Features

The 180 Series Rotary Shear Directional Control Valve, model 185-L0G by WEBTEC, is engineered for high-pressure hydraulic systems, ensuring precise directional control with near-zero leakage. With a maximum flow of 15 L/min (4 US gpm) and a pressure capacity of up to 700 bar (10,000 psi), this valve is suitable for demanding industrial environments. Its robust construction features aluminium and black phenolic thermoset plastic body materials, complemented by carbon steel internals, guaranteeing durability and reliability.

Designed to operate within fluid temperatures ranging from -30 to 120°C (-22 to 248°F) and ambient temperatures from -20 to 50°C (-4 to 122°F), this valve is compatible with mineral oils meeting ISO 11158 standards. The 9/16" -18UN #6 SAE ORB porting ensures secure connections, while NBR seals provide effective sealing under high-pressure conditions. Weighing 1.3 kg (2.9 lbs), this valve is both lightweight and compact, making it an ideal choice for various hydraulic applications.

What types of fluids can be used with the 180 Series Rotary Shear Directional Control Valve?
Answer by: Customer Support on Jun 21, 2025, 7:50 AM
This valve is compatible with mineral oils that meet ISO 11158 standards. If you need to use other types of fluids, you can request additional compatibility information.
Question by: Clint P on Apr 27, 2026, 8:51 AM
700 bar is a serious pressure rating, what kind of applications is this valve actually built for?
Answer by: Customer Support on Apr 28, 2026, 9:47 PM
For high-pressure hydraulic circuits where leakage between ports would cause real problems, this rotary shear design holds up to 700 bar (10,000 psi) with near-zero internal leakage. That kind of rating puts it in range for test bench work, industrial press circuits, and similar high-demand systems where a standard spool valve would bleed off too much to be useful.
