API 607: Fire-Safe Design for Industrial Applications

Bray’s Media Containment Unit (MCU) offers unparalleled sealing performance for demanding industrial ball valve applications, including high cycle, low temperature, high-temperature, and steam applications, enhancing safety and environmental protection, ensuring operational reliability and compliance with environmental standards.

Bray’s MCU is designed to prevent unintentional and undesirable emissions, leakage or discharge. In the event of a primary stem seal failure, the MCU’s secondary seal prevents leaks, while the MCU’s side port can be used for fugitive emissions monitoring, leak detection, fugitive emission diversion, as a Positive Pressure Seal, and as an emergency repair mechanism, enabling sealant injection through a button head check valve.

Constructed from investment cast stainless steel, Bray’s MCU is corrosion-resistant and suitable for harsh environments. Available in sizes ranging from 1/4" to 10" (6.35mm to 254mm), Bray MCU’s can be pre-installed at the factory for Triad Series, 7000/8000 Series, S7500/S7700 Series, F15/F30 Series, RF15/RF30 Series, and S85 Series. MCU’s can also be retrofitted through easy field installation.

By utilizing Bray’s MCU, industrial plants can significantly reduce operating costs and unscheduled maintenance events such as Leak Detection and Repair (LDAR) minimizing production downtime and maximizing productivity.
