1 Body & Cover

The FlexCheck valve body and cover is EN 1563: EN JS 1040 ductile iron for increased durability. Flanges are available drilled PN10, PN16 or ANSI B16.1 Class 125

2 Rubber Lining- Optional

Lining of internal surfaces will extend product life where the media is either erosive or corrosive

3 Door/Disc

Fully moulded door incorporating a steel disc for rigidity and nylon reinforcement in the hinge area that enhances flexibility and operating performance

4 Interchangeable

The face to face dimensions on most FlexCheck valves are identical to BS5153 face to face dimensions, which enables fitting without pipeline modification

5 Installation

Can be installed in horizontal or vertical pipelines (flow must be upwards) and in close proximity to pumps where space is a premium

6 Virtually Maintenance Free

As the FlexCheck has only one moving part and no bearings, pivot pins, mechanical hinges, linkages, mechanisms or packing, its simplicity in design and operation ensures minimal maintenance
