HAWE Type Solenoid Valve | GR2-2 GR2-3 GS2-2 GS2-12 GZ3-1 | Leak-free Seated Valve

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

Product Overview: The HAWE GR, GS, and GZ Series are widely recognized as premium direct-operated seated valves in the hydraulic industry. Unlike conventional spool valves, this series utilizes a cone or ball seating principle to achieve true zero-leakage performance. This makes them the ideal choice for hydraulic circuits requiring long-term pressure maintenance, such as clamping systems, outrigger locking, and press controls.

This selection highlights key configurations including G24 (24V DC), GM24 (with rectifier plug), and A24 (AC power) options. It features the high-performance GR2-2/3, the compact GS2-1/2/12, and the damped-response GZ3-1R models.

Key Technical Advantages:

• Absolute Zero Leakage: The seated architecture ensures absolutely no internal bypassing in the closed position, preventing cylinder drift and maintaining consistent system pressure.

• Extreme Pressure Capability: Ruggedly constructed to handle operating pressures up to 400 Bar to 700 Bar (depending on model), far exceeding the limits of standard spool valves.

• Wet-Pin Solenoid Engineering: Armatures operate fully immersed in oil for superior self-lubrication and heat dissipation, resulting in quiet actuation and an extended mechanical service life.

• Contamination Tolerance: Highly resistant to fine particles in hydraulic fluid, with a self-cleaning seating action that significantly reduces the risk of valve sticking.
