The Dwyer MSV-SD340 is a compact 2-way ball valve designed for fluid shutoff and isolation in instrumentation and industrial systems. Its 316 stainless steel body provides a durable construction for demanding fluid-handling applications.
The valve incorporates a microfinished ball and PTFE seats to provide a reliable seal and smooth operation. Its straight-through flow channel helps minimize pressure drop through the valve, making it suitable for compact process and instrumentation installations.
With a 3/8" tube fitting connection and 6.35 mm orifice, the MSV-SD340 can be integrated directly into compatible tube-fitting panels and process lines. The valve is rated up to 1500 psig (103 bar) and operates across a temperature range of -40° to 350°F.
For applications requiring a smaller tube connection, the Dwyer MSV-SD220 provides a compact 2-way configuration with a 1/4" tube fitting, 316 stainless steel body, and 3.18 mm orifice.
