HD-Z2FS – check valve
Ensure consistent, secure, and highly precise actuator speed control with the HD Z2FS Series. Available through Thm Hydraulics, this double throttle check valve is engineered specifically to limit the main or pilot fluid flow across two separate actuator connections. Operating seamlessly at maximum pressures up to 315 bar and handling flow rates up to 200 L/min, the Z2FS is a critical component for tuning the exact extension and retraction speeds of your hydraulic cylinders. Featuring a space-saving sandwich plate design and conforming to global mounting standards, this valve provides the exact meter-in or meter-out control required to maintain peak performance and synchronization in complex industrial systems.
Core Technical Specifications:-
- Component Architecture: Sandwich Plate Throttle Check Valve (Double Flow Control)
- Model Type: HD-Z2FS
- Maximum Operating Pressure: Up to 315 bar
- Maximum Flow Capacity: Up to 200 L/min
- Flow Regulation: Limiting of main or pilot flow with two service ports
- Control Modes: Configurable for Meter-In or Meter-Out control
- Standardization: Porting pattern to DIN 24 340 Form A, ISO 4401, and CETOP-RP 121H
Key Features & Engineering Advantages:-
- Dual-Port Flow Limiting: Independently controls the fluid flow to and from two separate actuator connections within a single valve body, allowing you to perfectly synchronize cylinder movements or tune exact operational speeds.
- Meter-In or Meter-Out Flexibility: Highly adaptable to your circuit's specific needs. Set it for Meter-In control to prevent load runaway on pulling applications, or Meter-Out control for steady, precise movement against opposing loads.
- Space-Saving Sandwich Design: Engineered for vertical stacking underneath standard directional control valves. This eliminates the need for bulky in-line flow control valves and complex external piping, drastically reducing your manifold's footprint.
- Universal Standard Compatibility: Strictly adheres to global DIN, ISO, and CETOP mounting patterns, ensuring this valve acts as a seamless, high-performance "drop-in" integration for standard manifold blocks worldwide.
- Uncompromising Durability: Forged to easily withstand continuous 315 bar pressure cycles without suffering from internal needle wear or compromised flow settings, guaranteeing long-term precision.
Ideal Industry Applications:-
The precise dual-port control and compact stacking design make the HD Z2FS Valve the premier choice for:
- Industrial Machine Tools: Tuning the exact feed speeds of cutting heads and automated work-holding clamps on CNC lathes and milling centers.
- Heavy Manufacturing Presses: Synchronizing the dual-cylinder downward stroke of massive metal forming and stamping equipment.
- Injection Molding & Plastics: Precisely controlling the ejector pin speed and mold-clamping velocities to ensure high-quality part production.
- Mobile & Lifting Equipment: Regulating the lowering speed of hydraulic booms and outriggers to prevent erratic, dangerous movements under heavy loads.
Why Choose the HD Z2FS Series?
- Dial In Your Exact Speed: Prevent jerky, aggressive machine movements by finely tuning the exact volume of fluid reaching your cylinders.
- Shrink Your System Profile: The sandwich plate design gives you advanced double-flow control without adding a single inch of external steel tubing or extra manifold blocks.
- Total Load Mastery: Whether your load is pushing or pulling, the ability to choose between meter-in and meter-out control means your machinery operates exactly as engineered, every single time.
