Ideal for corrosive industrial applications, this HAYWARD true union ball valve has a tough PVC body that won’t rust or corrode. Model features a fine-pitch seal retainer thread that allows for accurate compensation for seat wear. The reversible seats if damaged, can be removed, turned over, and reinstalled to ease valve repair. The double O-ring stem seal can provide up to twice the leakage protection of models with only a single stem seal. Valve design allows you to attach a mounting bracket directly to the valve without the need for glued or clamped-on mounting pads.
