ASCO™ Series 381 Solenoid Valves
asco-series-381-ss
The ASCO Series 381 is a line of high-flow, low-temperature solenoid valves designed to withstand harsh and corrosive environments.
Its broad operating temperature range of -60° C to 80° C for both media and ambient temperature allows for use in extreme conditions. The 381 Series is capable of passing the CSA (No. 139) endurance test to 100,000 cycles (10,000 cycles at -60° C and 90,000 cycles at 80° C).
