Top-mounted Ball Valve'150LB'WCB

Our Top-Mounted Ball Valve is designed for heavy-duty industrial applications where reliability and ease of access are non-negotiable. Featuring a unique top-access design, this valve allows for internal inspections and parts replacement while the valve body remains bolted to the pipeline. It is the gold standard for high-pressure, critical-flow environments.

Core Advantages

  • Top-Mounted Accessibility: The bonnet is located on the top, allowing technicians to remove the ball and seats without dismantling the entire piping system.

  • Zero Leakage Integrity: Utilizing a high-precision seat design that ensures a bubble-tight seal in both high and low-pressure scenarios.

  • Integral Body Casting: The single-piece body construction eliminates the risks associated with multi-piece bolted joints, providing superior resistance to pipeline stress.

  • Emergency Sealant Injection: Equipped with secondary sealant injection fittings for both the stem and seat areas to handle emergency leak situations.

  • Versatile Mounting Pad: Built-in ISO 5211 mounting pad for easy "top-mounted" installation of electric or pneumatic actuators.
