Description
Covering 15 mm to 50 mm at PN 16, this is Leader’s air Release Valve, Single Ball Type. Supplied as part of a range covering the sizes and ratings commonly specified for industrial and building services installations. Grey cast iron to IS 210 keeps the cost sensible in the larger sizes, provided the duty is steady rather than shock-loaded. Taper BSPT threads seal on the thread itself, which suits duties where a parallel thread and washer would be awkward. Fitted at the high points of a circuit, where trapped air would otherwise block flow. Every size in the range is listed above with its catalogue number and price.
