A penetration type gate valve is a control valve composed of a long stroke cylinder and a penetrating knife gate valve. Through type knife gate valve, the gate is extended and a through-hole of the same diameter is machined on the gate. The gate is tightly attached to the valve seat for opening and closing movement without detachment. This penetrating knife gate valve operates more smoothly, has superior sealing performance, and the medium does not stay in the valve chamber, achieving a complete flow state.
