ZSSO series O-type fixed ball valveDetailed product description：

The ZSSO series O-type fixed ball valve adopts an upper and lower stem fixed valve core (shaft supported) and a movable sealing seat design. Work is more stable. It has automatic compensation function, high shear force and self-cleaning function when the bi-directional sealing valve seat rotates without gap. Especially suitable for the on/off of imperial fibers, suspensions with small solid particles, and viscous media. This product can be widely used in automation control systems for industrial sectors such as papermaking, petrochemicals, chemical engineering, metallurgy, electricity, environmental protection, petroleum, and light industry.

characteristic
1. The O-type fixed ball valve adopts a fixed ball design, and the relative moving parts are made of self-lubricating materials with extremely low friction coefficient, resulting in low operating torque. In addition, the long-term sealing of the sealing grease makes the operation more flexible.
2. The valve adopts a high platform structure and ISO5211 connection standard, which can make the installation of electric/pneumatic actuators more specialized.
3. The O-type fixed ball valve adopts a full bore or reduced bore design, with low flow resistance.
4. The metal hard sealed O-type fixed ball valve adopts a bidirectional metal movable sealing structure, with automatic compensation and self-cleaning functions, and superior sealing performance.
5. The O-type fixed ball valve adopts a fixed ball design and adds a pre tension spring, making the ball valve have automatic pressure relief function.
6. Each ball valve has two movable sealing seats that can seal in both directions, so there is no need to consider the flow direction of the medium during installation.
7. Featuring a fire-resistant and anti-static structure, conductive springs are installed between the valve stem and valve body, as well as between the valve stem and ball body, to prevent static electricity from igniting flammable media. Ensure system security.
8. The fire-resistant structure provides dual protection. In the event of a fire that burns the sealing ring, all sealing parts of the ball valve can form a metal to metal hard sealing structure.
9. Automatic pressure relief structure, when the liquid medium trapped in the valve chamber vaporizes due to temperature increase, resulting in abnormal pressure rise in the chamber, the medium in the chamber can rely on its own thrust to push the valve seat and automatically relieve pressure, thereby ensuring valve safety.
10. Optional pneumatic, electric, hydraulic, as well as pneumatic and electric adjustable types. Please refer to the section on actuators and regulating valves in this book for details.
