Straight Needle Valve for Pool Plumbing

The Hayward NVA4050T is a straight needle valve designed for pool and spa plumbing systems. It provides precise flow control for maintenance and isolation tasks. Pool owners and service technicians use it to regulate water movement through filtration lines. The valve suits residential and light commercial installations requiring reliable shut-off.

Glass-Filled Polypropylene Body with FNPT Connection

The valve body and handle are moulded from glass-filled polypropylene for chemical resistance and structural strength. A 1/2 inch FNPT thread connects directly to standard pipe fittings without adapters. The integrated stem and PTFE seal create a tight closure that resists leakage under pressure. Installation requires only common plumbing tools and thread sealant.

Rated for 150 psi at 70 Degrees F

The valve handles a maximum pressure of 150 psi at a temperature rating of 70 degrees Fahrenheit. Flow capacity reaches 5 gallons per minute through the straight pattern. The compact height of 3 3/8 inches and 5 inch length fit tight equipment pads. Construction meets ASTM D1784 standards for material quality.
