Double Flange Butterfly Valve , Marine Ductile Iron ,NBR Lined , JIS F7480
PRODUCT INTRODUCTION
Description
Double flanged valve design for services in the water treatment industry. Butterfly Valves are renowned throughout the chemical, petrochemical, Garlock process, and many other industrial sectors for their quality, performance and reliability in demanding conditions.
Feature
The centric disc offers bidirectional service and allows with its symmetric shape high Kv (Cv) values.
Dry shaft design.
The inside body is protected by a bonded rubber liner extending over the flanges.
Primary stem sealing by preloaded contact between flatted seat surface and rounded polished disc-hub area exceeds the pressure rating of the valve and prevents leakage through shaft area to atmosphere.
A secondary sealing is provided by the interference fit between shaft and shafthole in seat at all positions.
Dirtscraper prevents moisture penetrating into the shaft area.
Bubble-tight shut off at full pressure rating.
Rounded, polished disc edge provides concentric sealing.
Actuator flange acc. ISO 5211.
Double flanged body design per EN 558 series 13 (short), series 14 (long) on request.
Excellent performance in media with sedimentation and contamination.
Suitable for severe vacuum applications and up to 16 bar (230 psi) drop tight shut off.
