ASCO 381 Series Low-Temperature Solenoid Valves
Brand: ASCOThe ASCO Series 381, also known as 8381, is a line of high-flow, low-temperature stainless steel 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).
Features- Higher flow results in faster process response time
 - Can operate to zero main pressure when using the externally piloted version
 - Compatible with speed control
 - Allows users to control flow to prevent abrupt opening/closing of actuator
 - Rugged 316L stainless steel body
