HAWE Type Valve | SG0R SG0W KR2-1 KS2-1 SWR1A7 | Leak-free Seated Valve | Directional Control

HAWE Type High-Pressure Leak-free Seated & Pressure Control Valves

Product Overview: This series encompasses high-performance solenoid directional seated valves and precision pressure control components. Unlike conventional spool valves, the SG0, KR, and KS series utilize a seated architecture where a ball or cone creates a metal-to-metal seal against the seat, achieving true zero internal leakage. This makes them the premier choice for hydraulic clamping systems, machine tool pressure-holding circuits, and high-safety hydraulic power units (HPUs).

This selection features essential models: including directional seated valves SG0R-AK and SG0W-CK, multi-functional valves KR2-1 and KS2-1, flow control valve FR2-1, and the integrated pressure-set valve SWR1A7-UD-1-G230-210. It also includes precision pressure compensation and check components RD11 and RC1E.

Key Technical Advantages:

• Zero-Leakage Integrity: The seated design ensures no internal bypassing in the closed position, maintaining system pressure over long periods and preventing actuator drift.

• Extreme Pressure Capability: Rugged construction allows for stable operation in high-pressure environments (up to 400-700 Bar depending on the model) where standard valves fail.

• High Contamination Tolerance: Superior resistance to fine particles in hydraulic fluid; the seating action provides a self-cleaning effect during closure.

• Wet-Pin Solenoid Design: Armatures operate fully immersed in oil for optimal cooling and lubrication, ensuring an extended mechanical service life under high-frequency duty cycles.
