Industry-Leading Metal-Seated Valves for Power and Mining Sectors

Bray Series M1 Severe Service Metal Seated Ball Valves provide exceptional reliability and performance in the most demanding flow control applications, including high temperature, high pressure, corrosive, erosive, critical, and lethal service. They are widely used in power, mining, oil & gas, refining, chemical, petrochemical, agrichemical, and specialty industries where safety and durability are essential.

Engineered for superior performance, Series M1 valves feature a heavy-duty drivetrain, 360° mate-lapped ball and seat, live-load packings, ISO 5211 actuator mounting, and an innovative stem alignment system that prevents side loads for extended packing life. Advanced thermal spray coating technologies—including HVOF, APS, PTA, and laser cladding—ensure long service life and minimal downtime in harsh operating environments.

Each M1 valve is engineered and manufactured to order, tailored to the customer’s specific process conditions. Bray’s expert engineering team analyzes factors such as temperature, pressure, erosion, corrosion, cavitation, flashing, and flow velocity to determine the optimal materials and valve trim.

With over 400 global locations, Bray is committed to delivering high-quality, application-specific severe service ball valves that meet the highest standards of performance, safety, and craftsmanship.
