Product Overview
The ATOS KR-012/4 35 is a modular flow control valve from the Atos KR series, engineered for precise regulation of actuator speed within hydraulic power circuits. As a sandwich-style modular valve, it is designed to be mounted between a directional control valve and its subplate, providing a compact, leak-free solution for metering flow to a single hydraulic line. The valve operates on a pressure-compensated, two-way flow control principle, maintaining a constant set flow rate regardless of variations in load pressure or system pressure. With a nominal size of 4 (NG4 / CETOP 3 interface), the KR-012/4 35 is ideally suited for industrial systems requiring accurate, repeatable speed control of cylinders and motors.

Engineering Features & Advantages
- Precision Flow Metering: Pressure-compensated design maintains a constant regulated flow independent of load and system pressure fluctuations, ensuring repeatable actuator speed control.
- Compact Modular Construction: Sandwich-style body integrates directly into existing CETOP 3 valve stacks, eliminating the need for additional piping and reducing installation footprint.
- Industrial Reliability: Hardened spool and precision-machined body built for continuous operation under severe industrial conditions and high cyclic duty.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Atos KR series modular valves and standard ISO 4401-03 subplate interfaces.
- Leak-Free Sealing: High-quality O-ring seals on all ports prevent internal and external leakage, maintaining circuit integrity and efficiency.
Typical Industrial Applications
The ATOS KR-012/4 35 modular flow control valve is widely deployed in plastic injection molding machines for precise mold clamping and injection speed control, metallurgical presses requiring accurate ram feed rates, CNC machine tools and machining centers for controlled axis movement, and general industrial hydraulic power units where repeatable cylinder or motor speed regulation is critical. Its modular design makes it particularly valuable in multi-actuator systems where individual flow control per circuit is required without additional piping complexity.
