Valve Selection Guides

Compare flanged, butt-weld, threaded and socket-weld ball valve interfaces, then use a 22-field RFQ checklist to normalize supplier bids.

Use a 30-field gate valve RFQ checklist to align service, standards, construction, operation, inspection, documents and commercial scope across supplier bids.

Compare API 600 and API 602 gate-valve scope, construction routes, line-class inputs, RFQ fields, testing and bid evidence before approving an offer.

Compare full-bore and reduced-bore ball valves by flow path, pigging, solids, package size and RFQ evidence before selecting a project valve.

Use this 36-field API 6D ball valve RFQ checklist to define scope, bore, isolation, actuation, tests and documents before comparing supplier bids.

Compare API 608 and API 6D ball valve scopes, current editions, RFQ fields, documentation and Monogram questions. Use the buyer workflow to prepare a technically comparable inquiry.

Compare metal seated and soft seated ball valves by media, temperature, shutoff, wear, torque and testing. Use the selection sequence and RFQ checklist to prepare a specification-based inquiry.

A floating ball valve seals by pushing the ball downstream under pressure. A fixed (trunnion) ball valve locks the ball

Every isolation valve decision starts with one question: gate or ball? Get it wrong, and you are not just losing

When a project specification calls for a globe valve above Class 600, the bonnet design becomes one of the first
