Description
RK KGB model Bidirectional Knife Gate Valve is engineered to excel in managing abrasive and corrosive slurries across diverse applications, focusing on performance and reliability. The valve utilizes a steel-reinforced molded seat to achieve zero-leakage bidirectional closure.
Features
A relief area has been cast into the valve body behind the seat. Designed to overcome problems common to other perimeter seated designs, the relief area greatly reduces compression set of the seat, allowing it to maintain a tight shutoff performance over varying service conditions.
Various wiper materials available in packing to provide gate support and stabilize packing seal
Clevis design and horizontal bolting stabilizes gate ensuring proper alignment.
Gear actuator / Electric actuators / Pneumatic actuators will be provide based upon request.
