The Model K300 Check Valve is a hydraulically operated No-Slam Check Valve. This valve opens when the pressure at the inlet exceeds the discharge pressure. A gradual rate of opening prevents sudden opening surges. When a pressure reversal occurs the higher downstream pressure is applied to the cover chamber through the control tube lines, and the valve closes drip tight. The rubber disc assures tight sealing.
The velocity of Open/Shutoff can be controlled by the 2-ways speed controller mounted on the bonnet.
Good to know! No pilot = no setting Speed controller is adjustable according to operating conditions. From smooth to fast closing/ opening.
