Description
Leader gate Valve (Bolted Bonnet, O/S & Yoke Type, Rising Stem), available 40 mm to 900 mm at Class 300. The straight-through bore means an open gate valve behaves much like a length of pipe. 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. Flanged ends make the valve straightforward to remove for servicing without cutting pipe, and are the norm once bore and weight rule out threaded joints. The table above gives the catalogue reference and price for each size in the range.
