Dwyer Instruments 3MSV-BD440 | Compact 3-way ball valve | Brass | 1/2" tube | 6.35 mm orifice

Part Number : 3MSV-BD440

The Dwyer 3MSV-BD440 is a compact brass 3-way ball valve with a 1/2" tube fitting connection and 6.35 mm orifice, designed for directional and diverting fluid control in instrumentation and small industrial systems. Its microfinished ball, PTFE seats, and straight-through flow design provide reliable sealing and smooth operation with low pressure drop.

Part Number: 3MSV-BD440

The Dwyer 3MSV-BD440 is engineered for applications requiring controlled routing or diversion of fluid flow between ports. Its compact 3-way configuration makes it suitable for instrumentation panels, tube-fitting assemblies, and small process systems where space-efficient flow control is required.

The valve features a brass body, 1/2" tube fitting connection, and 6.35 mm orifice. Its microfinished ball and PTFE seats provide a reliable, low-torque seal for smooth valve operation.

The straight-through flow design helps minimize pressure drop through the valve. The 3MSV-BD440 is rated for pressures up to 1500 psig (103 bar) and temperatures from -40° to 350°F, making it suitable for a variety of instrumentation and fluid-handling applications.

For applications requiring stainless steel construction, the Dwyer 3MSV-SD440 provides the same 1/2" tube fitting connection and 6.35 mm orifice with a 316 stainless steel body.
