| Valve shut-off and throttling | Mating sealing or flow-control surfaces exposed to pressure and repeated cycling | Valve seats, balls, plugs, stems, cages and trim components | Erosion, cavitation, leakage-path wear, impact and corrosion-assisted binder attack | Match medium, solids, pressure drop, temperature, cycle and mating material | Carbide blank, ground seat or trim, lapped sealing surface or assembled selected component |
| Pump sealing and shaft support | Rotating or stationary sealing, bearing and guidance position around shafts | Seal rings, bushings, sleeves, thrust parts and bearing components | Abrasive wear, dry running, thermal distortion, edge damage and loss of clearance | Review fluid, lubrication, speed, pressure, mating face, clearance and surface finish | Ring or sleeve blank, finish-ground bore/OD, lapped face or drawing-based part |
| Spray, dispensing and flow restriction | Orifice and metering surface controlling jet, spray pattern, dose or pressure | Nozzles, orifice inserts, needles, seats, poppets and restrictors | Orifice enlargement, jet erosion, clogging abrasion, seat wear and corrosion | Match media chemistry, particle size, flow velocity, pressure, orifice geometry and cleanability | Nozzle blank, precision bore, finished insert, lapped seat or component assembly |
| Slurry and abrasive-fluid handling | High-wear passage, liner, choke or change-of-direction area in process equipment | Liners, sleeves, choke inserts, wear rings, plates and custom flow parts | Particle erosion, sliding abrasion, cavitation, localized impact and corrosion | Use solids concentration, particle shape, velocity, angle of impingement and shutdown cycles | Wear blank, machined flow component, carbide-steel assembly or coating-related finished part |
