Part Number: 3MSV-SD340
The Dwyer 3MSV-SD340 is a compact 3-way ball valve engineered for directional flow control in instrumentation and small industrial systems. Its 316 stainless steel body provides a durable construction for demanding instrumentation applications, while the 3/8" tube fitting connection allows direct installation into compatible tubing systems and process lines.
The valve features a 6.35 mm orifice and a microfinished ball with PTFE seats, providing a reliable, low-torque seal. Its straight-through flow design helps minimize pressure drop while supporting efficient fluid routing.
With a maximum pressure rating of 1500 psig (103 bar) and an operating temperature range of -40° to 350°F, the 3MSV-SD340 is suitable for instrumentation applications where flow needs to be directed or diverted between ports rather than simply turned on or off.
For applications requiring a brass body, the Dwyer 3MSV-BD340 provides the same 3/8" tube fitting connection, 6.35 mm orifice, and 3-way configuration with a brass body.
