Utilizes a cylinder to drive the gate up and down, resulting in fast opening/closing.
These adopt floating connections to provide reliable one-way seals. The floating connection helps distribute friction evenly, increasing service life.
Sealing surfaces are lined with anti-wear ceramics, offering excellent resistance to abrasion.
Easy for transportation, installation, and maintenance.
The cylinder drives the gate to move downwards via the stem, engaging the sealing surfaces of the gate and body, thereby closing the valve. The reverse movement makes the valve open.

Installation, Use & Maintenance
Clean the valve and remove any defects that may have occurred during transportation.
Ensure that the marks and nameplate on the valve align with operating requirements.
This valve can be installed on pipelines at any angle.
The valve should be either fully open or fully closed when in use. Using it as a throttle valve may result in faster wear.
Store in a dry, ventilated room with periodic checks to prevent rust.
Avoid knocking during transportation to prevent damage.
