Ross Controls SV27NC305407PSAA1D Solenoid Valve

Ross Controls SV27NC305407PSAA1D is a SV27 Series normally closed, 3/2 safety solenoid valve with external monitoring and DPST feedback, designed for Safety Category 2 and Performance Level c in pneumatic safety circuits. This 24 VDC coil variant (voltage code 1D) uses a solenoid pilot and CNOMO electrical connection, with optional L-O-X manual lockout for energy-control applications. The 305407 PSAA variant aligns with a 540 body size and 3/4" ports, enabling safe exhaust sensing and zone-level lockout functionality directly at the valve. In this configuration, the valve provides a dedicated safety feedback path from the actuator to the control system through DPST contacts.
