Industrial Valve carries several products for severe-service environments, including Flow-Tek Series M4 ball valves from Bray. These quarter-turn valves are suitable for power plant steam vents and drains, and isolation or blowdown of steam, water, and other fluids.

Series M4 valves have a ball and seat that are 360° mate-lapped to create a spherical interface and are composed of/coated in the same material, so the ball and seat expand at the same rate during thermal cycling. CNC-machined alignment of the body, bracket, and stem prevents side-to-side motion, and 2-forged, heavy-walled unibody construction eliminates any potential for shell leakage. 

Specifications

Following is an overview of Flow-Tek Series M4 specifications. (For more details, please visit our product page where you can download the product manual and brochure).

Installation and Maintenance 

These valves must be flushed of any debris before installation. The valve should be positioned so that primary sealing occurs at the lower-pressure end. 

When welding, make sure the temperature of the valve body does not exceed 1100°F. (Flow-Tek forbids post-weld heat treatment in a kiln; only localized PWHT is allowed). 

Flow-Tek Series M4 valves are designed for longevity but do require regular preventative maintenance in accordance with Flow-Tek’s specified pressure, corrosion, and temperature parameters.
