Fully-welded Ball Valve
Overview:
Fully-welded ball valve is widely used in various fields. Compared with common casting steel ball valve, the fully-welded ball valve is more stable and which has much higher performance. Moreover it has much longer service life. The valve is applied to various pipelines in city gas, central heating, petroleum, chemical industry, ship building, steel plant, CNG station, etc. It could be directly installed underground, large-scaled valve well is not needed. It provides reliable operation for long-term.
Specifications:
Size: DN 15~600
Pressure: CL 150~600
Body material: WCB, A105, F1 1, F22, F304, F316, CF8, CF8M, WCC
Applicable temperature: -29~150℃
Applicable medium: water, oil, natural gas, acid or alkaline mediums
Features:
It adopts integrated welded, there is no external leakage.
The seat consists of PTFE sealing ring and spring, which is highly adaptable when pressure and temperature changed.
The stem is designed into anti-leak structure, which ensures there is zero-leakage
The material of body is the same as adjacent pipe’s so as to avoid uneven stress distribution and deforming caused by earthquake or the vehicle passed by.
The body is light and easy to heat-insulating.
The underground ball valve could be directly installed under the earth, there is no need to build large-scaled valve well, but only needs small-scaled shallow valve well on the ground, so that it is significantly saving project costs and time.
The body length and stem height could be customized according to design requirements.
The ball is high-accuracy processed, so that it is flexible to operate, no unwanted interference.
