What are the characteristics of O-type fixed ball valve?

The O-type fixed ball valve adopts a fixed ball design, and the relative moving parts are made of self-lubricating materials with a very small friction coefficient, so the operating torque is small. In addition, the long-term sealing of the sealing grease makes the operation more flexible.

Features:

1. The metal hard-sealed O-type fixed ball valve adopts a two-way metal movable sealing structure, with automatic compensation function and excellent sealing performance.

2. The O-type fixed ball valve adopts a fixed ball design and adds a preload spring, so that the ball valve has an automatic pressure relief function.

3. Each ball valve has two movable sealing seats, which can be sealed in both directions, so it is not necessary to consider the flow direction of the medium during installation.

4. It has a fire-proof and anti-static structure, and a conductive spring is set between the valve stem and the valve body and between the valve stem and the ball to avoid static ignition to ignite flammable media. Make sure the system is secure.

5. Double protection of refractory structure, but in case of fire and the sealing ring is burned, all parts of the ball valve can form a metal-to-metal hard sealing structure.

6. Automatic pressure relief structure, when the liquid medium remaining in the middle cavity of the valve is vaporized due to the increase of temperature, so that the pressure in the middle cavity rises abnormally, the medium cavity medium can automatically release the pressure by pushing the valve seat by its own thrust, thereby Make sure the valve is safe.
