Dwyer Instruments 3MSV-SD550 | Compact 3-way ball valve | 316SS | 3/4" tube | 11.10 mm orifice
The Dwyer 3MSV-SD550 is a compact 316 stainless steel 3-way ball valve with a 3/4" tube fitting connection and 11.10 mm orifice, designed for directional and diverting flow control in instrumentation and small industrial systems. Its microfinished ball and PTFE seats provide a reliable, low-torque seal, while the straight-through flow design helps minimize pressure drop.
Part Number: 3MSV-SD550
The Dwyer 3MSV-SD550 is a compact 3-way ball valve engineered for directional flow control in instrumentation and small process systems. Its 316 stainless steel body provides durable construction for applications requiring stainless steel components.
The valve features a microfinished ball and PTFE seats that provide a reliable, low-torque seal. Its straight-through flow design helps keep pressure drop to a minimum, making it suitable for applications where efficient flow routing is important.
The 3/4" tube fitting connection allows the valve to connect directly to compatible tube-fitting panels or process lines without requiring additional adapters. With an 11.10 mm orifice, the 3MSV-SD550 is sized for instrumentation applications that require flow to be routed or diverted between ports rather than simply opening or closing a single line.
The valve is rated for pressures up to 1500 psig (103 bar) and operates across a temperature range of -40° to 350°F.
