Brass Solenoid Valves - 2/2 Normally Open

Brass 2/2 normally open solenoid valves (NO) are designed to remain open when de-energised and close when electrical power is applied. This fail-safe open configuration makes them ideal for applications where flow must continue in the event of power loss. Unlike normally closed valves, normally open solenoid valves allow media to pass by default, only shutting off when energised. This makes them suitable for safety-critical systems and continuous flow processes. Available in durable brass construction, these valves are suitable for a wide range of media including water, air, light oils and other compatible fluids. Key Features: Normally open (fail safe open) operation Closes when energised Brass valve bodies for durability BSP threaded connections Available in multiple voltages (12V, 24V, 110V, 230V) Suitable for air, water and light oils Operation Types: Direct Acting (Zero Rated): Suitable for low pressure or vacuum applications Pilot Operated (Pressure Assisted): Requires minimum pressure differential for higher flow rates Typical Applications: Safety and fail-open systems Cooling and water circulation systems Drain and bypass systems Industrial process control For applications requiring fail-safe shut-off, view our normally closed solenoid valves.
