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 with attention to the details of spindle sealing and seat design.

LOW COST MAINTENANCE
The seat and disc can easily be replaced under a planned maintenance schedule. This replacability does not affect the valve's function as this seat is positively located in machined grooves in the valve body.
