Eaton Weatherhead 530 Needle Valve

The Eaton Weatherhead 530 is a straight needle valve made from brass with a 1/8 in MNPT to 1/4 in tube connection. It is intended for fluid-control tasks where fine metering is required. The metal seal and steel handle are rated for 150 psi and temperatures from 0 to 250 degrees F. The compact body measures 1 5/16 in long and 1 1/32 in high.

Suitable applications and limits

This valve suits installers who need a small brass needle valve for straight-line flow regulation at moderate pressure. It is not for systems that exceed 150 psi or require a different end configuration such as flare or compression fittings. Buyers needing larger pipe sizes or alternative body materials should look at other models.

Deciding specification

The critical specification is the 1/8 in MNPT by 1/4 in tube connection combined with the 150 psi pressure rating. These two figures determine whether the valve fits the existing piping and handles the system pressure. Verify both values against your installation requirements before ordering.

Questions about this item

How do I confirm the valve is sealing correctly after installation?

Pressurise the line up to 150 psi and check for leaks at the MNPT and tube connections; the metal-to-metal seal should hold without weeping.

What comes with the valve and what must I supply?

The valve body, brass stem, metal seal and steel handle are included; you must provide 1/8 in MNPT and 1/4 in tube fittings plus thread sealant.

Which size should I choose for a 1/8 in male pipe thread to 1/4 in tube connection?

Select the 1/8 in x 1/4 in straight needle valve; it matches that exact MNPT-to-tube configuration.
