Service conditions decide the final configuration.
Temperature, pressure, media, installation and maintenance strategy often change seat design, body construction, materials, end connections and actuator selection.
Cryogenic Ball ValvesLNG and low-temperature service where material toughness, cavity relief and extended stem design must be considered together.Metal Seated Ball Valveshigh temperature, abrasive, erosive or dirty media where soft seats are not appropriate.High Pressure Ball ValvesClass 900, 1500 and 2500 service where forged construction, RTJ/BW ends and high-integrity seat behavior are often required.Subsea Ball Valvessubsea isolation where external pressure, corrosion resistance, actuation interface and project qualification are design inputs.Hydrogen Ball Valveshydrogen service where material compatibility, stem sealing, leakage control and test requirements need specific review.Underground Ball Valvesburied pipeline installations requiring stem extensions, external coating, drainage/vent extensions and long-term corrosion protection.
Manufacturing & Inspection Evidence
Support technical claims with real records.
Manufacturing capability is supported by product, machining, assembly and hydrostatic-test evidence. Inspection records can cover material traceability, NDE/NDT, PMI, dimensional inspection, coating inspection and pressure testing.
