ASCO™ 317 Quick-Exhaust Solenoid Valves
The ASCO Series 317, also known as 8317, is a line of quick-exhaust solenoid valves designed for quick venting to 0 psi through the exhaust orifice to quickly shift control valves.
The valves are available in low-power, intrinsically safe, voltage-ranging, and harsh environment constructions. The 317 Series is suitable for a wide variety of applications such as automotive, analytic and diagnostic instruments, biofuels, dust collector systems, and heating equipment.
