SPV series 2/2 Solenoid Popet Valves are used as circuit elements in industrial hydraulic industry. This Valve is in a position to prevent the passage of pressure from the pump in the hydraulic system. When the electric coil installed on it is given (12V-24V-220v), it creates a magnetic field and moves the pin inside the valve to prevent the pressure coming from the hydraulic pump by turning the system on/off. When the magnetic field (electricity) is cut, the system is turned on/off again.
