In 1991, SEKISUI entirely renewed the valve design and introduced more reliable model in order to meet the severe requirements of clients. |
| SEKISUI, being a integrated plastic manufacturer, incorporated all the know-how they have achieved though out the years and redesigned the valve from the scratch, all the parts and components, including the materials. |
| As the result, SEKISUI introduces the totally renewed vacuum valve model, which achieved extensively high endurance and stable performance against all climates. |
