Rexroth Type Z2S16 & Z2FS22 Series Valve | R900328797 Z2S16-1-5X | R900443176 Z2FS22

Rexroth Type Z2S16 Pilot Check Valve & Z2FS22 Twin Throttle Valve

Product Overview: This product line features two essential control components for industrial hydraulic systems: the Z2S16 Series Sandwich Plate Pilot Operated Check Valve and the Z2FS22 Series Twin Throttle Check Valve. Both valves utilize a standard sandwich plate design, compliant with ISO 4401 mounting standards, allowing for direct stacking under directional valves to simplify piping and minimize installation space.

The Z2S16-1-5X/2 (R900328797) is engineered for absolute actuator locking to prevent cylinder drift under load. Meanwhile, the Z2FS22-8-3X/S2 (R900443176) provides precise flow adjustment for controlling the movement speeds of large-scale actuators. These are widely used in heavy-duty forging presses, steel metallurgy equipment, large injection molding machines, and mobile machinery.

Key Technical Advantages:

• Heavy-Duty Load Holding (Z2S Series): Utilizes a balanced poppet design for smooth opening even under high-pressure conditions, ensuring safe load retention and release.

• Dual Precision Throttling (Z2FS Series): Supports independent speed adjustment for both Port A and Port B, featuring excellent linear regulation characteristics.

• High-Pressure Industrial Standards: Rated for operating pressures up to 315 Bar (31.5 MPa), capable of handling severe continuous duty cycles.

• Precise Part Number Matching: Strictly follows Rexroth standard specifications to ensure 100% interchangeability and reliability for replacement tasks.
