Bevel Gear Rising-stem Bi-directional Rubber-Lined Knife Gate Valve 

Product Description: JZW rubber lined knife gate valve uses two rubber seats to clamp and compress the gate. When the gate is fully opened, the two sealing seats fit and close by themselves to form a short rubber pipe. With the internal pressure of the pipe, the strength sealing effect is better. At the same time, when the valve is fully open, the gate can be replaced online without removing the whole valve. The valve adopts full rubber sealing with strong wear resistance and full diameter fluidity. It is suitable for industrial and mining pipelines that require valve wear resistance
