Bubble Tight Closure and Long Life

INTRODUCTION

Today's ships have to work hard. With the extensive use of automated systems, minimum manning levels, extended journeys and quick turn round times, maintenance time is at a premium. Equipment must be ultra reliable and also meet the latest standards.

LONG LIFE AND LEAK TIGHT
The 722F are designed to meet all of these requirements. It is a tough valve made to international standards with worldwide marine approvals. Long term leak tightness is achieved
