Overview of Brass Solenoid Valve Normally Open NBR Diaphragm

Description
This normally open brass solenoid valve is designed to allow flow when de-energised and close upon electrical activation. Fitted with an NBR diaphragm, it provides reliable sealing and long service life in systems handling water, air, and light oils. The robust brass body and simple solenoid design make it suitable for continuous-duty applications where fail-open operation is required.
