THM – Z2FS16, 22 – Check valves
Gain absolute, synchronized control over your high-capacity hydraulic actuators with the THM Z2FS16 / Z2FS22 Series Double Throttle Check Valve. Engineered as a heavy-duty sandwich plate valve, this component is designed to precisely limit the main or control fluid flow for two separate actuator connections simultaneously. Built to effortlessly process massive flow rates up to 360 L/min and sustain extreme operating pressures up to 350 bar, the Z2FS series delivers the robust, uncompromising flow regulation required by modern fluid power systems. Whether configured for meter-in or meter-out control, this valve provides the exact tuning capabilities necessary for the heavy-duty machinery that drives major civil and road infrastructure projects.
Core Technical Specifications:-
- Valve Architecture: Double Throttle / Check Valve (Sandwich Plate Design)
- Standard Sizes: NG16 (Size 16) and NG22 (Size 22)
- Maximum Operating Pressure: Up to 350 bar
- Maximum Flow Rate: Up to 360 L/min
- Mounting Standards: Porting pattern to DIN 24 340 form A and ISO 4401
- Flow Control Configuration: Configurable for Meter-In or Meter-Out Control
Key Features & Engineering Advantages:-
- Dual Actuator Synchronization: Expertly limits and regulates the fluid flow for two distinct actuator connections within a single, space-saving valve block, ensuring synchronized movement for complex machine functions.
- Meter-In or Meter-Out Flexibility: The versatile internal geometry allows engineers to set the valve for either meter-in (controlling fluid entering the cylinder) or meter-out (controlling fluid exiting the cylinder) operation, perfectly matching the specific load dynamics of your circuit.
- Triple Precision Adjustment Options: To ensure exact flow calibration in the field, the valve can be equipped with one of three specialized adjustment elements:
- Lockable Rotary Knob with Scale: Provides tactile tuning with a secure locking mechanism to prevent accidental changes due to machine vibration.
- Spindle with Internal Hexagon and Scale: Offers a highly secure, tamper-resistant adjustment method for permanent factory settings.
- Standard Rotary Knob with Scale: Delivers quick, easy visual reference and rapid adjustments for dynamic machinery.
- Space-Saving Sandwich Design: The stackable sandwich plate configuration perfectly aligns with DIN and ISO standards, allowing for seamless vertical integration directly into custom manifolds without the need for bulky external piping.
- Massive 360 L/min Capacity: Despite its stackable footprint, the internal galleries are hydro-dynamically optimized to process massive volumes of fluid without generating excessive heat or pressure drops.
Ideal Industry Applications:-
The massive flow capacity, dual-throttle precision, and rugged 350-bar resilience make the Z2FS Series an essential control element for:
- Heavy Civil & Road Machinery: Providing perfectly synchronized, high-volume flow control for the dual lifting cylinders and massive leveling screeds on large-scale asphalt pavers, road milling machines, and heavy motor graders.
- Large-Scale Earthmoving Equipment: Regulating the massive fluid demands of secondary attachments and pilot circuits on heavy tracked excavators and high-capacity wheel loaders.
- Heavy-Duty Mobile Material Handling: Serving as the precise speed-control mechanism for the dual boom extensions and stabilization outriggers on heavy-tonnage industrial cranes.
Why Choose the THM Z2FS Series?
- Uncompromising Precision: Three specialized adjustment methods guarantee exact flow scaling for your specific application.
- Heavy-Duty Integration: The standardized DIN/ISO sandwich plate design saves critical space in crowded engine bays.
- Total Synchronization: Controls two high-volume actuators simultaneously from a single, robust block.
