Frequently Asked Questions

Find quick answers to some of the most common questions

Is the Frontier S3 ball valve repairable in the field?

Yes. Designed in two-piece and three-piece forged steel configurations (threaded or bolt-together), the S3 allows technicians to quickly disassemble the body in the field to replace seats, seals, and internal components without taking the valve body out of service.

Is the Frontier S3 Ball Valve fire-safe certified?

Yes. The S3 is manufactured to API 607 fire-safe standards, featuring secondary metal-to-metal back-up seating to ensure positive pressure containment in the event of severe fire exposure.

How does the stem packing design prevent leaks in the Frontier S3 Ball Valve?

The S3 features an internally loaded, blow-out proof stem with adjustable stem packing backed by Belleville spring washers. This live-loaded setup automatically compensates for thermal expansion and seal wear to prevent stem leaks.

What end connections are available for the Frontier S3 Ball Valve?

The Frontier S3 is available with RF flanged, RTJ flanged, Butt Weld (BW), and Socket Weld (SW) end connections, depending on size and pressure class.
