Knife Gate Valves

Knife Gates designed for positive shut off

The Meyer Knife Gate Valve is designed for positive shut off of all free flowing bulk material. It can be used in feeding, dust collector hoppers, silos or other conveying equipment. The valve’s open throat is designed to assure there is no clogging of bulk material; the robust design can handle dust to 1/4″ coarse grain granulated material. Standard operator is a manual hand wheel with the option of a pneumatic operator. As one of the top Knife Gate Valve manufacturers, you can rest assured that our units will provide exceptional performance.

The unit consists of a cast iron housing with a stainless steel gate supported by a series of rolling cams and an inlet seal positioned beneath the inlet retaining ring sandwiching the gate at the top. The unit incorporates graphite aramid fiber packing as standard with the option for Teflon and spring loaded packing.
