Dwyer Instruments HBV-M08 | 2" 3-piece alloy-c ball valve | Cv 400
The Dwyer HBV-M08 is a 2" NPT, 3-piece Hastelloy C ball valve designed for demanding high-pressure and corrosive-service applications. Manufactured from ASTM A494 Type CW12MW Hastelloy C, it provides a corrosion-resistant solution for chemical process lines and other applications where standard stainless steel may not be suitable.
The valve features an ISO 5211 actuator mounting pad for direct installation of pneumatic or electric actuators, making it suitable for automated process isolation. Its 3-piece construction supports in-line servicing without requiring removal of the entire valve from the pipe run.
Part Number: HBV-M08
The Dwyer HBV-M08 is a high-performance 3-piece ball valve designed for demanding process applications involving corrosive media, high pressure, and elevated temperatures. Its body is machined from ASTM A494 Type CW12MW Hastelloy C, a material selected for demanding chemical process environments where corrosion resistance is critical.
The 2" NPT female connections provide a threaded installation for compatible process piping. The 3-piece body construction allows in-line servicing without requiring the valve to be completely removed from the pipe run, helping simplify maintenance procedures.
For automated applications, the HBV-M08 incorporates an ISO 5211 actuator mounting pad. This allows compatible pneumatic or electric actuators to be mounted directly to the valve. The high-cycle, live-loaded stem packing system is designed to maintain sealing through repeated operation, while the non-blowout stem includes lockout capability for safe isolation.
With a Cv of 400, a maximum pressure rating of 2000 psi (137.9 bar) under ASME B16.34 Class 900, and a maximum operating temperature of 425°F (218°C), the HBV-M08 is designed for demanding corrosive and high-temperature process service.
For a smaller valve in the same range, the Dwyer HBV-M07 provides a 1-1/2" NPT configuration with a Cv of 120.
