Dwyer Instruments 3MSV-SD220 | Compact 3-way ball valve | 316SS | 1/4" tube | 3.18 mm orifice
In instrumentation and industrial systems, the Model 3MSV-SD220 Compact 3-Way Ball Valves are the ideal option for fluid directional control. Easy operation and a high-quality seal are guaranteed by the PTFE seats and microfinished ball. There is less pressure drop possible because of the straight through flow channel design. There are two types of valve bodies available: brass and 316 stainless steel. Additional durability and safety in the event of overpressure are provided by the blow-out-proof ball and stem.
