ASCO™ 037 3/2 Way Manual Reset Solenoid Valves
The ASCO Series 037 3/2-way manual reset solenoid valves have high-flow, high-pressure bodies with manual reset to prevent inadvertent valve start-ups.
Electrically tripped (trips when energized), no-voltage release (trips when de-energized), or free-handle constructions are available. The valves are ideal for controlling critical processes in refining and chemical industry applications. Some models can control aggressive fluids, including steam
