Description
Leader globe Valve (Bolted Bonnet, O/S & Yoke Type, Rising Stem, Full Bore), available 15 mm to 40 mm at Class 1500. A regulating valve. The disc approaches the seat square-on, which is why it tolerates throttling that would wreck a wedge. A rising stem gives visual confirmation of position without touching the handwheel, at the cost of clearance above the valve. Forged A105 gives a dense, void-free body — why forged construction is specified for small-bore high-pressure duty. Socket-welded ends suit small-bore high-pressure lines where a threaded joint would be a weak point. The table above gives the catalogue reference and price for each size in the range.
