Top entry Ball Valve

Wegman valves offers various types of ball valves

Grove BT top entry ball valve

Top entry ball valve

As the name already indicates you can enter the valve from the top. The body is made from 1 piece to minimize leak paths. The ball and seates are inserted from above. While the cover is also accessible while the valve is in the pipe line service & maintenance can be done much quicker than with a side entry design.

In the standard versions the valves are suitable for transmission pipelines, pumping, compression and
re-injection units, offshore platforms, onshore terminals, pig traps, measuring stations and surge relief skids.
Whenever ball valves are used in critical service applications, in-situ field repairability with quick turnaround is often needed.

Our brand: Grove

The top entry ball valves are full in-line field repairable, thus eliminating long down times.
Top entry ball valves have complete flexibility in the use of materials for body, trim and seal gasket selections.
For this reason, they can be trimmed to meet your most severe applications.
The top entry ball valves are sized to withstand the external loads from the pipeline or from the manifolds even when the bonnet, the ball and the seats are removed for maintenance. They can also be welded directly onto the pipeline or the manifold assembly.
The bonnet-body construction allows the use of various grades of carbon steel, stainless steel and other alloys thus complying with most severe service conditions.
The top entry ball valves can also be adapted for special applications such as abrasive fluids, low temperature service, sequencing service (low and high temperature), subsea installations and LNG plants.

Wegman offer the Grove BT1 and BT2 top entry ball valves
