Manual Knife Gate Valve

Product Description

The opening and closing member of the manual knife gate valve is a shutter. The direction of movement of the shutter is perpendicular to the direction of the fluid. The blade is cut by a blade-shaped shutter that can cut the fiber material. The valve body does not actually have a chamber, and the gate is guided at the side. The groove is lifted and lowered, and the lug at the bottom is pressed against the valve seat. If a high medium sealing property is required, an O-shaped sealing seat can be used for the two-way sealing.

Feature

1. Lifting ram sealing surface can scrape the adhesive on the sealing surface and automatically remove debris.

2. Stainless steel rams prevent seal leakage caused by corrosion.

3. The hard all-gold sealing surface can guarantee the sealing wear resistance and requirements.

4. There is no groove on the sealing surface of the valve body, and no accumulation is generated, which can ensure flexible opening.

5. Short structure length, can save raw materials, installation space and effectively support pipeline strength.

6. The scientific upper sealing stuffing box design makes the upper sealing safe and effective and durable.

7. The triangular bracket saves raw materials and guarantees the required mechanical properties.

8. The guide block on the valve body makes the gate move correctly, and the four extrusion blocks ensure the effective sealing of the gate.

9. The valve body rib design improves the strength of the valve body.

10. Stainless steel stem is durable, the studs make the opening and closing more rapid.

11. The drive mechanism can be arbitrarily selected.

12. 150 or more caliber, fully enclosed structure, more effective to open and prevent leakage.

13. The sealing surface of the fluororubber can achieve the sealing effect and increase the operating temperature.

14. The rubber sealing surface is directly vulcanized in the valve body and will not fall off.
