The ZPR750F O-port Soft-Seat Shutoff ball valve is a widely used control valve consisting of a valve body, ball, stem, seats, and actuator. When the valve shaft rotates, the ball turns accordingly while the resilient seats deform to achieve effective sealing, thereby changing the valve's open/close status.
This valve features: Compact structure, Reliable sealing performance, Quick response, Precise flow characteristics. The sealing surfaces maintain constant contact with the ball in the closed position, providing excellent erosion resistance against process media. With simple operation and easy maintenance, it can be equipped with pneumatic actuators, solenoid valves, and limit switches for on/off control applications. Suitable for: General service media: water, solvents, acids, natural gas. Severe service media: oxygen, hydrogen peroxide, methane, ethylene. This valve finds extensive applications across multiple industries including petrochemical, power generation, pharmaceuticals and water treatment.

| Features | Description |
| Bonnet Metal Gasket | Selecting metal gasket materials tailored to specific media prevents PTFE aging issues while significantly enhancing sealing performance. |
| Anti-Blowout Stem | Anti-ejection design, effectively preventing stem blowout caused by gland loosening. |
| Anti-Static Structure | An electrostatic discharge device is installed between the ball, stem, and valve body to eliminate static electricity accumulation. |
| Fire-Proof Design | Automatic Metal Seal: In case of fire, the non-metallic seat melts, allowing media pressure to push the ball against the metal seat, creating a metal-to-metal hard seal. |
| Superior Sealing | Daikin TFM-1600 PTFE seat and V-shaped packing enhance sealing performance while delivering superior self-lubrication and reduced operating torque. |
| Standard Mounting Platform | Design with deep packing box and cast bracket isolates actuator from body heat, maintaining ISO 5211 compliance for universal pneumatic/electric actuator compatibility |
| High-Strength Stem Connection | Octagonal connection shafts are manufactured from Grade 45 steel or 2Cr13 alloy through hot-forging Multi-Application and CNC center machining, delivering superior fit accuracy and enhanced structural rigidity. |
