ANGLE NEEDLE VALVE (MALE X FEMALE)
ANGLE NEEDLE VALVE (MALE X FEMALE)
An Angle Needle Valve (Male x Female) is a precision flow control valve designed with a 90-degree flow path, featuring a male inlet and female outlet connection. This configuration is ideal for installations where space is limited or where the process line needs to change direction without additional fittings. The needle valve provides fine control over flow rate, making it suitable for high-precision applications involving gases, steam, or liquids.
This type of valve is commonly used in instrumentation lines, pressure gauges, sampling systems, and control panels across industries such as oil & gas, chemical processing, power generation, and pharmaceuticals.
- 90-degree angle body design: Saves space and simplifies routing of process lines.
- Threaded male inlet x female outlet: Typically available in NPT, BSPT, or BSP connections.
- Precision needle stem: Allows fine throttling and positive shut-off.
- Packing options: PTFE, graphite, or other materials for leak-proof performance.
- Blow-out proof stem: Ensures safety in high-pressure applications.
- Material choices: Stainless steel, brass, carbon steel, or special alloys.
- Pressure ratings: Available in ratings up to 6000 psi or more depending on size and material.
- Compact installation with built-in 90° direction change.
- Reduces the need for elbows or additional fittings, minimizing leak points.
- Provides precise flow regulation in both on/off and throttling operations.
- Protects downstream instruments by controlling flow surge or pulsation.
- Suitable for high-pressure, high-temperature, and corrosive environments.
- Improves efficiency and layout in confined instrumentation panels or skid systems.
