Description

1/4" & 3/8" Stainless Steel 3/2 Way Solenoid Valve 0–12 Bar Normally Closed


The ST08 and ST10 Series are compact direct acting 3/2 way normally closed stainless steel solenoid valves designed for reliable control of air, water, vacuum, gases and low viscosity fluids. Manufactured from AISI 303 stainless steel with stainless steel internal components, these valves provide excellent corrosion resistance together with higher flow rates and operating pressures for demanding industrial and OEM applications.

Available with a choice of orifice sizes, seal materials and Nass Magnet Class H coils, the ST Series offers operating pressures up to 12 Bar and flow rates up to 9.29 L/min. Optional ATEX Ex m coils are available for hazardous area installations.
