Overpressure protection for shipboard systems. Confirm set pressure, back pressure, inlet/outlet size and certificate requirement.
Pressure control for downstream equipment and systems. Confirm inlet/outlet pressure range, media, capacity and connection size.
Tank pressure and vacuum protection for cargo and service tanks. Confirm set/vacuum pressure, tank type and mounting connection.
Relief protection for auxiliary systems and equipment. Confirm set pressure, capacity, inlet/outlet size and service media.
This category covers safety, relief, pressure-reducing and breather valves. Because these products protect shipboard systems, set pressure, backpressure, media, inlet and outlet conditions and certificate scope are confirmed before quotation.
Before RFQ, confirm standard scope, pressure ratings, certificate and inspection requirements, and IMPA-code data.
Provide the protected system, standard or model, inlet and outlet sizes, set pressure and tolerance, backpressure, service medium and temperature, materials, quantity, certificate requirement and target schedule.
Calibration sets and verifies opening pressure, tolerance, reseating pressure and sealing performance against the product standard, protected-system requirement, test medium, temperature, backpressure, instrument calibration and any nominated survey requirement. Adjustment is performed by an authorized workshop or service party, and the record is traceable to the product and order.
No. Size alone is not a substitution basis; inlet and outlet pressure, flow range, stability, downstream equipment and installation details must be reviewed together.
Classification-society certificates and inspection requirements are applied for by product and order; the applicable society, scope and survey stage are confirmed before quotation.
