Direct Operated 2 Port Solenoid Valve Air Medium Water vacuum By providing a bumper and clearance, we reduced the collision sound of the core when ON (when the valve is open). Because of the clearance, when using highly viscous fluids such as oil, the armature does not get stuck and the responsiveness when OFF (when the valve is closed) is improved. ∗ Can be used with heated water.
