Dwyer Instruments HBV-M04 | 3/4" 3-piece alloy-c ball valve | Cv 32
The Dwyer HBV-M04 is a 3/4" NPT, 3-piece Hastelloy C ball valve with a Cv of 32, 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-M04
The Dwyer HBV-M04 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 adequate resistance to the process media.
The valve has 3/4" NPT female connections and a 3-piece construction that allows in-line servicing without removing the valve from the pipe run. The integrated ISO 5211 actuator mounting pad accepts compatible pneumatic or electric actuators, making the HBV-M04 suitable for automated process control.
A high-cycle, live-loaded stem packing system helps maintain sealing performance during repeated operation. The non-blowout stem also incorporates lockout capability to support safe isolation during servicing and maintenance.
With a Cv of 32, a maximum pressure rating of 2000 psi (137.9 bar), and an operating temperature capability of up to 425°F (218°C), the HBV-M04 is designed for demanding corrosive and high-temperature process applications.

Who This Product Is Best For
The Dwyer HBV-M04 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 3/4" 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-M04 at the required process isolation point in the 3/4" 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.
