1½" Stainless Steel Normally Open Solenoid Valve – NOSPU225A-14
A pressure-assisted 2/2 way normally open stainless steel solenoid valve designed for higher-flow applications where a minimum pressure differential is available. Suitable for air, water, oils and compatible gases, with options for WRAS-approved seals, oxygen service degreasing and ATEX-certified coils.
Designed to remain open without power and close only when energised, making it ideal for fail-safe fluid control systems where flow must be maintained during power loss.
