What s the Difference between a Knife Gate and a Slide
A slide gate utilizes a stainless steel rectangular slide plate to shut off or open the flow of dry material. The slide plate actuates between two compression-loaded hard polymer plates. In the closed position the compression load on the blade prevents the dry bulk material and the conveying air from escaping through the valve or into the

These valves should not be used to throttle water flow but only as a purely on/off regulator. The valve s design consists of the body and the internal gate with the handle and stem. The gate is a wedge or circular plate that is risen or dropped to regulate the valve. Gate valves can serve a dual purpose of an adapter and a valve.

Introduction to Gate ValveThe Process Piping
Apr 13 2020 · A gate valve is a multiturn valve meaning that the operation of the valve is done by means of a threaded stem. As the valve has to turn multiple times to go from open to closed position the slow operation also prevents water hammer effects. Gate valves should not be used for regulation or throttling of flow because
