Description
3/8" Normally Open Stainless Steel Solenoid Valve 0–12 Bar – Shako SPU220AN-03
A high-performance 2/2 way normally open stainless steel solenoid valve designed for aggressive, corrosive and high-purity fluids where fail-open operation is required. Manufactured from 316 stainless steel and fitted with an 18.5 W coil system, the SPU220AN-03 provides reliable operation from 0 Bar up to 12 Bar without requiring a minimum differential pressure. Based on the SPU220A assisted-lift platform.
