Hayward® NVA Series Needle Valves

Hayward® NVA Series needle valves are used for accurate metering of fluids. Turning the thumbwheel moves a tapered piston into the PTFE seat to control the flow down to a few drops per minute.

  • PVC or glass-filled polypropylene
  • PTFE seat
  • Precision molded, fine pitched stem threads
  • Permit this very fine metering flow control
  • Flanges for panel mounting
  • Maximum temperature: 150°F (PVC) & 260°F (PP)
