Top-entry Ball Valve

Top-entry Ball Valve

ONERO Top-entry ball valves feature easy in-line maintenance. The top of the valve can be removed to gain access to the ball and seats without removing the entire valve from the piping system. Top-entry Ball Valve is specially designed and developed for lower operating torque, easy maintenance, soft or metal seat, fire-safe, double block and bleed, bi-directional operation, and flexible design.

Features and Benefits

- Easy maintenance

Removing the bonnet from the valve allows free access to the ball and the seats, which can be taken out without the need for any special maintenance tools.

- Advanced Seal Design

The seats are always in contact with the ball to provide an effective, tight seal even at low differential pressures.

- Emergency and Regular Lubrication

Allows for emergency sealing and regular lubrication through a built-in grease valve to ensure smooth operation.

- Double block-and-bleed (DBB)

Capable of isolating both upstream and downstream media, with automatic pressure relief for safety.

-Fire-safe design, anti-static device, Emergency sealant injection fitting for seat and stem

- Extended Stem

Offers customizable stem lengths for ease of maintenance, especially in underground installations

- Low Torque Operation

Designed with a fixed ball and sliding bearings to reduce friction and ease operation
