The Dwyer BV2M109 is a two-piece stainless steel ball valve designed for reliable shutoff in chemical and general industrial applications. Its 3" female NPT configuration is suitable for larger process piping where durable stainless steel construction and dependable isolation are required.
The valve body, ball, and end cap are manufactured from investment-cast CF8M stainless steel, while the stem is made from 316 stainless steel. The valve uses 15% glass-reinforced PTFE (RTFE) seats to provide bubble-tight shutdown up to 1000 psi (69 bar) WOG.
Actuator mounting pads are included as standard, allowing the BV2M109 to be paired with compatible pneumatic or electric actuators without requiring a separate mounting bracket. This makes the valve suitable for applications where future or existing automated control is required.
The BV2M109 has a specified operating temperature range from -20° to 450°F (-29° to 232°C). Its stainless steel construction and RTFE seating make it suitable for a wide range of chemical and industrial service applications.
For a smaller pipe size in the same valve family, the Dwyer BV2M108 is the adjacent model with a 2-1/2" connection size.
