HEX BODY NEEDLE VALVE (FEMALE X FEMALE)

HEX BODY NEEDLE VALVE (FEMALE X FEMALE)

A Hex Body Needle Valve (Female x Female) is a compact, high-precision valve with a hexagonal-shaped body and female-threaded ports on both inlet and outlet sides. The hex body allows for easy wrench tightening during installation, while the needle stem provides precise flow regulation and secure shut-off.

This valve is commonly used in instrumentation systems, hydraulic and pneumatic lines, gas and fluid control, and in high-pressure testing applications across industries such as oil & gas, petrochemicals, power plants, and laboratories.

  • Hexagonal body design: Enables easy gripping and installation using standard tools.
  • Female x Female threaded ends: Typically available in NPT, BSP, BSPT, or metric threads.
  • Tapered needle stem: Offers fine adjustment and tight shut-off capability.
  • Blow-out proof stem: Ensures operational safety under high pressure.
  • Non-rotating tip: Reduces seat wear and maintains sealing integrity.
  • Compact size: Ideal for panel mounting and tight spaces.
  • Material options: SS316, SS304, brass, carbon steel, Monel, Hastelloy, etc.
  • Packing options: PTFE, graphite, or metal-to-metal sealing based on temperature and fluid compatibility.
  • Pressure range: Up to 6,000 psi (414 bar), depending on size and material.
  • Space-saving design for compact instrumentation systems.
  • Precision flow control in both gaseous and liquid service.
  • Ease of installation using standard spanner or wrench.
  • Minimized risk of leakage with robust body and quality threading.
  • Ideal for corrosive and high-pressure environments.
  • Long service life due to durable materials and rugged design.
