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; our knife gate valve’s standard design is robust and can handle dust to 1/4″ coarse-grain granulated material. No other pneumatic knife gate valve manufacturers can boast this level of performance. The standard operator is a manual handwheel 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.
