Features & Benefits:
The centric disc offers bidirectional service and allows with its symmetric shape high Kv 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 shaft hole in seat at all positions.
Dirt scraper prevents moisture penetrating into the shaft area.
Bubble-tight shut off at full pressure rating.
Rounded, polished disc edge provides concentric sealing.
