Z2FS6-30B Stacked Unidirectional Throttle Valve Hydraulic Valves Product Huade

Z2FS6-30B Stacked Unidirectional Throttle Valve is a high-precision flow control component manufactured by Huade Hydraulic, designed for integration into stacked valve assemblies in industrial and mobile hydraulic systems. This valve enables precise regulation of fluid flow in one direction while allowing free reverse flow, ensuring smooth actuator speed control and system stability.

1. Stackable Design:

• Compact ISO 4401-compliant mounting allows direct installation between directional valves and subplates, minimizing space requirements and external piping.

• Dual-functionality: Combines throttle and check valve capabilities, providing flow control in one direction and unrestricted reverse flow.

2. Precision Flow Control:

• Type 2: Hex lock nut with protective cap.

• Type 3: Lockable knob with scale.

• Type 5: Scalable spindle with hex key.

• Type 7: Scalable knob.

• Adjustable flow via 4 modulation types:

• Bidirectional configurability: Rotating the valve 180° switches between inlet and outlet throttling.

3. Robust Performance:

• Max pressure: 31.5 MPa.

• Flow capacity: Up to 80 L/min.

• Temperature range: -20°C to +80°C (compatible with mineral oils HL/HLP and phosphate esters HFD-R using fluorocarbon seals).

4. Reliability in Harsh Conditions:

• Cast iron construction with hardened internal components.

• Low leakage design meeting NAS1638 Class 9 cleanliness standards.

• Mobile Machinery: Excavators, loaders, and cranes for boom/arm speed control.

• Industrial Systems: Presses, plastic injection molds, and automation equipment.

• Agricultural Equipment: Tractors and harvesters for implement stability.

• Simplified Maintenance: Stacked design reduces leak points and installation time.

• Flexibility: Independent control of dual flow paths (A and B ports) for complex circuits.

• Cost-Efficiency: Replaces multiple discrete valves, lowering assembly and maintenance costs.

This valve is ideal for engineers seeking reliable, compact flow control solutions with minimal pressure drop and high customization. Huade’s Z2FS6 series ensures compatibility with global hydraulic standards, backed by proven durability in high-demand environments.
