Dwyer Instruments HBV-M02 | 3/8" 3-piece alloy-c ball valve | Cv 8
The Dwyer HBV-M02 is a 3/8" NPT, 3-piece Hastelloy C ball valve with a Cv of 8, designed for high-pressure and corrosive-service automation. It features an ISO 5211 actuator mounting pad for pneumatic or electric actuator installation and is rated for pressures up to 2000 psi (ASME B16.34 Class 900).
Part Number: HBV-M02
The Dwyer HBV-M02 is a 3-piece ball valve machined from ASTM A494 Type CW12MW Hastelloy C, making it suitable for demanding chemical process applications where standard stainless steel may not provide sufficient resistance to the process media.
The valve features 3/8" NPT female connections and a 3-piece body design that allows in-line servicing without removing the valve from the pipe run. Its ISO 5211 actuator mounting pad supports direct installation of compatible pneumatic or electric actuators for automated valve operation.
A high-cycle, live-loaded stem packing system helps maintain sealing performance through repeated cycles. The non-blowout stem also includes lockout capability to support safe isolation during maintenance and servicing.
With a Cv of 8, a maximum pressure rating of 2000 psi (137.9 bar), and a maximum operating temperature of 425°F (218°C), the HBV-M02 is built for demanding corrosive and high-temperature process duty.

Who This Product Is Best For
The Dwyer HBV-M02 is suitable for process engineers, chemical processing facilities, controls contractors, and industrial automation professionals who require a corrosion-resistant, automation-ready ball valve in a compact 3/8" NPT size.
It is particularly suited to demanding chemical or high-temperature process applications where Hastelloy C construction, actuator compatibility, and in-line serviceability are important.
How to Use
- Install the HBV-M02 at the required process isolation point in the 3/8" NPT line.
- Ensure the valve is correctly aligned and securely connected before commissioning.
- If automation is required, mount a compatible pneumatic or electric actuator to the ISO 5211 pad.
- Commission the actuator, if fitted, and verify smooth open/close operation before startup.
- Follow applicable site procedures for pressure isolation, actuator commissioning, and maintenance.
