Cast Steel Gate valves Glofa Supplied can be fully opened and fully closed to be used for cutting in the pipeline.The entire flow channel is a straight-through passage when the valve is fully-open, and the pressure loss is minimum.Gate valve is usually for working condition in which the valve is not opened or closed frequently, Itâ??s not suitable for adjustment or throttling.
The most important feature of the cast steel gate valve of Glofa produced is that they can be ensured that the permissible leakage rate can be lower than that specified in API 6D and API 600, and the middle shaft sealing can pass the USA VOC leakage test. The wedged gate of the Glofaâ??s gate valve provides tight sealing even at low differential pressure. Grooved wedge guided and fitted by body, assures proper and consistent seal regardless of valve position, and also minimizes seat wear and damage, since seating surfaces of the wedge and seat are in contact during less than 5% of the total wedge travel.

Forged steel gate valves Glofa produced which sizes are 3â?³(DN80) and smaller, compared with castings, forged valve bodies offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Forged steel gate valve Glofa offered have superior properties of heat preservation and cold preservation, the valveâ??s bore diameter are same as the pipelines and the medium flows in straight lines, resulting in that the resistance force are small and could prevent the heat losing effectively, this type valve are better choice for the fluid which is easy to solidify and with higher viscosity
Glofaâ?? forged steel gate valve is with wedged type sealing structure, it is sealed by the wedge compressing on the seat, this sealing type make it possible unaffected by the pipeline pressure difference. The forged steel gate valve Glofa design are with self-cleaning structure, the fluid flow through the valve along on the sealing surface in 360 , which could eliminate the crash to the seat by the fluid in high speed, also flush away the dirties on the sealing surface.
