Metal Seat Swing Check Valve - PN16, DN50-DN300
WHAT IS A SWING CHECK NON RETURN VALVE?
The swing check non-return valve allows fluid to flow through whilst the vertically hinged disc prevents any reverse flow. The force of the flow in the correct direction allows the valve to open whilst back flow forces the valve plates to close.
