Metal Sealing Ball Valve
Brief Introduction
Ball Valve is not only own with the functions of opening quickly, easy to maintain, good sealing but also safety fire-safe and Antistatic designs. Lung Yun manufactures designs various kinds of ball valves for one-piece, two-piece, three-piece, thread end, socket weld end, butt weld end, flange type, full port, reduce port. The selection of ball valve material includes stainless steel, carbon steel, and cast iron. The working pressure from 1000 psi to 6000 psi application of you chose. Designs of different sealing are as client's requirement. Chose the suitable ball valve to use in piping system, Nai Bang is the best supplier.
Specifications
1. Various driving types
The top pad of valve designed according to ISO 5211, which is convenient for connection and exchange of various drivers.The common driving types are manual, electrical, pneumatic and pneumatic/hydraulic.
2. Automatic body cavity relief
When the body pressure going up un-normally as the unstable factor, the trunnion ball valve downstream seat will be pushed by un-normally pressure, and the release theunnormal pressure automatically, it doesn't damage to the sealing of upstream seat.
3. Low torque in operation
The self-lubricated bearings are installed at the friction of stem, resulting in wear resistance, fiexibility of operation and low torque.
