<strong>Premier</strong> Tilting <strong>disc</strong><br />
<strong>swing</strong> Check Valve<br />
• PN6, PN10 and PN16<br />
Description<br />
The <strong>Premier</strong> Tilting Disc Check is of the Eccentric Butterfly valve<br />
design and is equipped with Dashpot which ensures that the valve<br />
is closed in two steps ie fast action during the first 90% of travel<br />
and controlled during the last 10% travel. This last 10% of travel is<br />
controlled by the Hydraulic Dashpot and is adjustable. Unlike most<br />
other Tilting Disc Check valves which use a Counterweight to speed<br />
up the closing action during the first 90% of travel, the <strong>Premier</strong><br />
Tilting Disc Check valve has a greater offset in the shaft to ensure<br />
that the weight of the door acts as Counterweight. The Dashpot can<br />
be controlled in both opening and closing directions to enable the<br />
<strong>Premier</strong> Tilting Disc Check valve to act as Pump Control valve on<br />
start-up. If extra fast closure is required, the counterweight can be<br />
added as an optional extra.<br />
Features<br />
• The valve seats at an angle of approximately 20º from the<br />
centreline which ensures a shorter travel of only 70º from<br />
fully closed to fully open and hence faster closing action.<br />
• Due to the Eccentric shaft design, the valve is in<br />
the normally open position during flow and the<br />
normally closed position during no flow.<br />
• Low opening pressure of only 80 kPa to fully open the valve.<br />
• Two-step closure – initially fast and last 10% slow<br />
and adjustable between 1 to 10 seconds.<br />
• The valve shaft is self lubricated for life<br />
