Back valve has many advantages such as improved safety and easy installation. It only provides a one-way fluid path. When the liquid flows in the flow direction, the check valve opens to pass; but when the liquid flows in the reverse direction, the check valve closes to prevent it from passing.
SC-400 should be installed horizontally.
