Product identity

The Hayward NVA1025T is a straight needle valve made from PVC with a 1/4 inch FNPT connection. It is designed for precise flow control in plumbing systems where chemical resistance and fine adjustment are required.

Fit and alternatives

This valve suits installers who need a compact, corrosion-resistant shut-off or metering device rated for 150 psi and 140 degrees Fahrenheit. It is not for buyers who require a larger pipe size, a different connection type, or a valve rated for higher pressure or temperature.

Deciding specification

The 1/4 inch FNPT connection size determines whether this valve matches the existing piping. Confirm the thread standard and pipe diameter before ordering to ensure a proper seal and fit.

Questions about this item

Does the PVC needle valve heat up or leak when left running at its 150 psi rating all day?

The valve body is PVC with FKM seals rated for 140 Degrees F and 150 psi, so continuous operation within those limits will not cause overheating or leakage.

What piping and fittings must I already have to install this 1/4 in FNPT needle valve?

You need 1/4 inch male NPT pipe threads on both sides of the installation point; the valve connects directly to those threads without additional adapters.

Will this straight needle valve thread onto older 1/4 inch NPT brass or steel fittings I already own?

Yes, the FNPT threads follow the standard taper so they mate with existing 1/4 inch male NPT metal or plastic fittings without cross-threading.
