Selection Guide
Class 1500 is used for high-pressure critical service. The rfq should be complete before pricing because material, ends, trim and actuation can significantly affect construction. For this valve design, buyers should also review plug geometry, lubrication/sleeve system, pressure balancing and port arrangement.
Final pressure-temperature limits, dimensions, operating torque and test values are confirmed against the applicable standard, approved drawing and project specification.

Typical project materials include WCB, LCC, CF8M, Alloy Steel. The correct grade depends on corrosion, minimum and maximum design temperature, toughness, hardness limits and the project material specification.
End Connections
Rtj and bw are frequently specified; exact ends must match the approved piping class. Available connection families for this product include RF, RTJ, BW.
Design & Engineering
For Class 1500, review pressure boundary design, material grade, trim, seat load, torque, actuator sizing and maintainability as one system. Also confirm plug design, port arrangement, lubrication/sleeve, material, end connection and operating method.
Oil and gas, refinery, metering, transfer, chemical and wastewater systems. Final suitability depends on the actual fluid, design temperature, corrosion conditions, cycling frequency and project specification.
Testing & Inspection
Expect tighter control of material traceability, nde, pressure tests and project documentation where specified.
RFQ Checklist

Buyer Questions
Provide valve size, Class 1500, design standard, body and trim material, end connection, operation, quantity, service fluid, design temperature and inspection requirements.
Typical project options include WCB, LCC, CF8M, Alloy Steel. Final material selection must follow the approved piping class and service conditions.
This product family includes RF, RTJ, BW. The correct connection depends on the line class, flange facing or weld preparation in the project specification.
Where the design allows it, gear, pneumatic, electric or hydraulic operation can be evaluated after operating torque, fail action and project requirements are confirmed.
