Knife Gate Valve

Characteristics

This bi-directional valve ensures 100% sealing within any given pressure. In open position, the valve seats form a tight extension of the pipeline causing absolutely no leakage onto the metal parts. When the valve is closed, the seats are displaced axially creating a reliable seal with the gate until it forms a complete closure.

Technical description

The Knife Gate Valve has an epoxy coated fully lugged body in nodular iron with integrated purge ports. The seats are flexible in an axial way and seals towards each other in the bore when the valve is in open position, protecting internal parts and the gate from the abrasive media. The solid top works provides excellent stability during operation. For security reasons it is always supplied ready to be locked in either open or closed position. The seats also form a sealing face on the valve flanges saving the need for gaskets.
