HAWE Type Solenoid Valve | GR2-2 GR2-3 GS2-0 GZ3-1 | Leak-free Seated Valve | G24

HAWE Type GR, GS & GZ Series High-Pressure Leak-free Seated Valves

Product Overview: This series encompasses high-performance solenoid directional seated valves, specifically the GR, GS, and GZ Series. Unlike conventional spool valves, the seated design utilizes a ball or cone pressed against the seat to achieve zero internal leakage. Engineered for ultra-high pressure applications, these valves are essential for hydraulic clamping systems, pressure-holding circuits, lifting equipment, and compact hydraulic power units (HPUs).

This selection features primary configurations equipped with G24 (24V DC) high-performance coils, including the standard switching GR2-2/3/4, the compact GS2-0/1, and the rapid-response GZ3-1 series (including damped variants).

Key Technical Advantages:

• Superior Zero-Leakage Integrity: The seated architecture ensures absolutely 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, with ratings up to 400-700 Bar (depending on the model).

• Wet-Pin Solenoid Engineering: Armatures operate fully immersed in oil for optimal cooling and lubrication, providing smooth actuation and an extended mechanical service life.

• Contamination Tolerance: Hardened internal components offer high resistance to fine particles in hydraulic fluid, with the seating action providing a self-cleaning effect.
