Water Seal Valves

This valve is complete shut-off valve for gas. The sphere body has two discs inside. These discs turn 90° centering the support shaft to open and close. After the discs come to the ‘close’ positions, a rod inside the support shaft comes out to press seal ring of the discs to the seat parts. This type valve has much more excellent efficiency, particularly as gas valve for large and middle caliber pipes, than conventional valves.
