• trunnion Design: ISO 7121 specifies the design requirements for trunnion ball valves, which feature a unique support structure. The ball is supported by an axis or shaft that extends through the valve body, providing additional stability and support.
• Support Structure: The trunnion design allows for better load distribution and reduces wear on the valve components. This design is particularly beneficial in high-pressure and high-flow applications.
• Operation: The ball is rotated by a stem connected to a handwheel or actuator, allowing for precise control over fluid flow. The trunnion design ensures smooth and reliable operation, even under demanding conditions.
• Enhanced Stability: The trunnion design provides additional support to the ball, enhancing stability and reducing wear.
• High-Pressure Capability: This design is suitable for high-pressure applications, ensuring reliable shutoff and flow control.
• Reduced Maintenance: The improved load distribution and reduced wear contribute to lower maintenance requirements and longer valve life.
• Floating Ball Design: ISO 6552 specifies the design requirements for floating ball valves, where the ball is not rigidly fixed to the stem. Instead, it floats within the valve body, allowing for better sealing and load distribution.
• Support Structure: The floating ball design relies on the contact between the ball and the seat for sealing. This design provides excellent sealing performance and is suitable for a wide range of applications.
• Operation: The ball is rotated by a stem connected to a handwheel or actuator, allowing for precise control over fluid flow. The floating ball design ensures reliable shutoff and minimal leakage.
• Excellent Sealing: The floating ball design provides excellent sealing performance, ensuring minimal leakage and reliable shutoff.
• Versatility: This design is suitable for a wide range of applications, including those involving corrosive fluids and high temperatures.
• Ease of Maintenance: The simpler design of floating ball valves often makes them easier to maintain and repair.
