Top Entry ball valve

Introduction of Top Entry Trunnion Ball Valve

 

A top entry ball valve is used to control fluid transmission in pipeline systems where quick shut-offs are required. The ball, stem, and actuator are assembled vertically, in that order, hence the name ‘top entry’. It has a detachable bonnet which provides access to internal parts of the entire valve. This makes it possible for repairs to be performed on the valve while it is still in-line.

We are experienced top entry valve manufacturers committed to offering premium quality to our customers. Our valves have multiple stem sealing, double block and bleed, as well as bi-directional class IV shut-off to ensure maximum flow control. They conform to API 6D pressure standards and ASME B 16.34 design standards thus making them ideal for critical service environments.

LUCKY6S top entry mounted ball valves range in size from NPS ½ to NPS 60 with either full bore or reduced bore valve balls. Depending on the application, they can be fitted with pneumatic, hydraulic, or gas actuators among many other valve operator options. Each unit, regardless of size, is built to perform with low torque and smooth gliding movements while maintaining maximum safety.

Top Entry Ball Valve Industrial Applications

 

Geothermal reinjection units – after energy extraction, geothermal fluids need to be injected back to the reservoir in measured amounts at a predetermined pressure. A top entry ball valve is applicable in controlling such dispensation.

PIG traps- top entry ball valves provide a safe way to insert or remove pipeline PIGS as they can withstand the high-pressure that goes along with PIG trap procedures. A full bore valve also provides adequate room for PIG traps.

Surge-relief skids –  the fast maneuverability of top entry ball valves is useful in operating pipeline surge-relief skids. They can be set to automatically open when the pressure reaches a set level and shut tightly again when the system is relieved.
