Needle Valve for Pool Plumbing

The Hayward NVA1050T is a straight needle valve built from PVC with FKM seals and a glass-filled polypropylene handle. It provides precise flow control in pool and spa plumbing systems where chemical resistance and durability are required. The valve carries a 150 psi pressure rating and a 140 degree Fahrenheit temperature rating.

Verify Pipe Size and Thread Type

Confirm that your existing plumbing uses a 1/2 inch FNPT connection before ordering. The valve body is PVC and the seal material is FKM, so ensure compatibility with the fluids and chemicals in your system. The maximum flow capacity is 5 gpm, so check that this meets your circuit requirements.

Inline Installation in PVC Systems

The valve installs inline using the FNPT threads and suits schedules that match the 1/2 inch pipe size. Its compact height of 3 5/16 inches and length of 2 1/2 inches allow it to fit in tight equipment pads. The straight body simplifies piping layout without extra fittings.

Questions about this item

Does the Hayward NVA1050T needle valve include any fittings or sealant in the box?

The package contains the valve body with FKM seals and a glass-filled polypropylene handle. Thread sealant or tape for the 1/2 in FNPT connections must be purchased separately.

Which pipe size and connection type does the NVA1050T model provide?

This model is built for 1/2 in pipe with FNPT threads, rated to 150 psi and 140 °F.

What does the 5 gpm maximum flow mean for a pool circulation system?

At the 150 psi pressure limit the valve passes up to 5 gpm, so size the pump and plumbing to stay within that flow rate.
