Design Basis
In Titanium Grade 2 Dual Plate Check Valve Class 300, the Dual Plate Check Valve construction determines the closure support, body arrangement and maintenance approach. Confirm bore or flow path, body joint, stem/shaft retention, seat support, anti-blowout features where applicable and access requirements against the approved GA.
Pressure-Boundary Material
For Titanium Grade 2 Dual Plate Check Valve Class 300, the pressure boundary is Titanium Grade 2. Commercially pure titanium used in selected seawater, desalination and chemical duties. Because this valve is Class 300 with Flanged / Wafer, verify the material condition, trim compatibility, bolting and any PMI/NDE or corrosion-control requirement as one package.
Pressure Class and Piping Interface
For Titanium Grade 2 Dual Plate Check Valve Class 300, the specified rating is Class 300 and the piping interface is Flanged / Wafer. Medium pressure service with heavier flanges, bolting and wall sections than class 150. Wafer versus flanged body selection changes bolting, face-to-face and installation requirements. Final dimensions and pressure-temperature suitability must therefore be checked against the selected material and design temperature, not inferred from class alone.
Seat and Seal Arrangement
For Titanium Grade 2 Dual Plate Check Valve Class 300, the listed sealing basis is Metal / Soft Seat. Metal seating shifts the design toward hardfacing/coating, lapping, higher torque and wear control rather than polymer-seat compliance. Confirm leakage acceptance, pressure/temperature limits and cycling together with the Class 300 loading and the selected Self-Acting operating method.
Operation and Actuation
For Titanium Grade 2 Dual Plate Check Valve Class 300, operation is Self-Acting. Self-acting operation depends on process differential pressure and closure dynamics rather than an external operator. The final operator or actuator basis should use the actual size, maximum differential pressure, Metal / Soft Seat friction/seating behavior and required operating or emergency time.
Service Conditions
No service qualifier is fixed by the product name, so Titanium Grade 2 Dual Plate Check Valve Class 300 should be released only after the actual fluid, temperature range, pressure cases, cycling and special service requirements are known.
Inspection and Testing
For Titanium Grade 2 Dual Plate Check Valve Class 300, tie MTC/heat traceability, dimensional inspection, PMI/NDE where specified, shell/seat testing, coating checks, witness points and final records to the approved API 594 / ASME B16.34 datasheet and ITP.
Documents Before Release
The manufacturing release for Titanium Grade 2 Dual Plate Check Valve Class 300 should reference the approved GA, material/trim schedule, seat/seal definition, operator or actuator data, test scope and required final documentation.
