J14W Angle Needle ValveOverview

The J14W angle-type needle valve is a small-bore instrument valve featuring an angle-style body, operated by rotating the handwheel to drive the stem and needle-type disc for precise opening and closing. Its sealing surface is directly machined from the valve body material (“W” type), forming a metal-to-metal hard seal. The angle-style design changes the flow direction by 90°, effectively saving installation space and reducing pressure loss. This valve is primarily used for root isolation of pressure gauges and transmitters, pipeline sampling, flow regulation, and draining/venting. It serves as a critical instrument accessory in industries such as petroleum, chemical, power generation, and pharmaceuticals, ensuring safe isolation and precise control of measurement systems.

J14W Angle Needle ValveCharacteristic

1.Angle-style structure for space saving: The 90° flow direction change suits space-limited installations or applications requiring pipeline direction changes, offering a compact design.

2.Flexible connection options: Various connection types including internal thread, external thread, or welded ends are available to meet different piping system requirements.

3.Needle-type disc for precise regulation: The needle disc cooperates with the seat to enable precise adjustment and control of small flow rates with excellent regulation performance.

4.Metal-to-metal hard seal for reliability: Sealing surfaces are directly machined from stainless steel, forming a wear-resistant metal-to-metal hard seal with long service life.

5.All-stainless steel corrosion resistance: Body and main components are made of 304/316 stainless steel, providing excellent corrosion resistance for various corrosive media.

6.High-pressure design: Robust body structure withstands high working pressures, suitable for high-pressure applications.

7

Reliable stem sealing: Multi-layer packing or PTFE sealing with gland prevents external leakage.
