WL24H-320P 304/316L Stainless Steel Fine Adjustment Valve with Barbed Connectors (Straight Through/Right Angle)

Product Overview

The WL24H-320P stainless steel fine adjustment valve is a high-precision valve specifically designed for precise control of micro-flow in high-pressure pipelines. Its "fine adjustment" feature stems from the precision valve stem transmission mechanism, enabling fine control of the opening degree. The product is equipped with barb fittings for easy connection to hoses; the straight and right-angle structural forms provide flexible options for complex system layouts. It is widely used in petroleum, chemical, laboratory, hydraulic systems and other occasions requiring high-pressure precision adjustment.

Model Meaning Interpretation (WL24H-320P)

• W: Represents valve
• L: May stand for throttling or fine adjustment function
• 24: May represent the structural form (here usually refers to right-angle type; straight type may correspond to a different code)
• H: Represents stainless steel valve body
• -320: Nominal pressure is 320 kgf/cm² (approximately 32.0 MPa)
• P: Valve body material is chromium-nickel-titanium stainless steel (such as 304/316L)

Detailed Explanation of Product Features and Advantages

1. Precision Fine Adjustment Mechanism

• Fine-Thread Transmission: The handwheel needs to rotate multiple turns for the valve stem to produce micro-displacement, achieving precise control of the opening degree with excellent adjustment linearity.
• Smooth Opening and Closing: The slow opening and closing speed can effectively prevent system water hammer (pressure impact) and protect downstream precision instruments.
• Precise Flow Control: Can accurately control micro-flow, meeting the process requirements of sampling, filling, experiments, etc.

2. Advantages of Barb Fitting

• Convenient Connection: The barb design facilitates the insertion and fastening of hoses, enabling quick and easy installation.
• Reliable Sealing: When used with a hose clamp, it can form a reliable sealed connection.
• Strong Adaptability: Can be adapted to hoses of different wall thicknesses, with flexible application.

3. Choice Between Straight and Right-Angle Types

Straight Type:

• Minimal flow resistance and pressure loss.
• Suitable for occasions with strict requirements on pressure drop.

Right-Angle Type:

• Saves installation space and can adapt to complex pipeline layouts.
• Facilitates changing the direction of fluid flow, making the system structure more compact.

4. High-Pressure Sealing and Stainless Steel Valve Body

• Tight Sealing: The valve disc and valve seat are precision ground with cemented carbide or body material to ensure reliable shut-off and small internal leakage.
• High-Pressure Design: Thickened valve body and reinforced structure ensure stable operation of the valve under 32MPa high pressure.
• Corrosion Resistance: 304 stainless steel has strong versatility; 316L stainless steel has better resistance to pitting corrosion and intergranular corrosion, suitable for harsher corrosive environments.
