Series F15/F30 Flanged ball valves are used in virtually every industry across the globe. Series F15/F30 Flanged ball valves are available in a variety of optional trims and configurations including resilient seated, metal seated, and v ball control valve trims. Series F15/F30 feature a flexible design, offering exceptional value and dependable operation across a wide range of service conditions in a rugged flanged ball valve design.

Series F15/F30 flanged ball valves are engineered to ensure bubble-tight shutoff and low operating torque. ½” – 2” sizes feature Flow-Tek’s Smart Stem technology with integral live load packing. 2 ½” – 12” valves utilize an independent packing gland which can be easily adjusted without removing mounting hardware or operator. The packing gland is contoured to uniformly distribute the load across the packing. The live load packing is self-adjusting due to its Belleville washers allowing it to compensate for environmental changes and wear, ensuring maintenance free operation and long cycle life. Larger sized valves feature a trunnion-type ball support to reduce operating torque.

All resilient seat materials ensure bi-directional, bubble tight sealing and feature relief slots on the seat outer diameter to relieve pressure past the upstream seat in case of an upset situation such as trapped gas in the valve body as well as positive preloading to ensure low pressure/vacuum sealing capability.

Non-Fire Safe and API 607 Fire Safe Valves:
Series F15/F30 valves are available as non-fire safe with standard stem seals or fire safe to API 607 with graphite stem seals.

Secure Mount
Series RF15/RF30 valves offer ease of automation due to an integrally cast actuator mounting pad that complies with ISO 5211 through 2” valve sizes.
