Description
Leader’s gate Valve (Pressure Seal Bonnet, O/S & Yoke Type, Rising Stem) is supplied in 50 mm to 200 mm at Class 900. Gate valves isolate rather than regulate: the wedge lifts clear of the bore, so an open valve costs almost no pressure drop. A rising stem gives visual confirmation of position without touching the handwheel, at the cost of clearance above the valve. A cast carbon steel body to ASTM A216 WCB handles the temperatures and pressures of steam and hot oil, where bronze or iron would not be rated. Butt-welded ends give a permanent joint with no potential leak path, used where the line is not intended to be broken. Full dimensions, catalogue references and current pricing for every size are listed in the table above.
