 The ball valve with extended stem is widely used in the pipeline of coal chemical industry, petrochemical industry, rubber industry, paper industry, pharmaceutical industry, etc.The extended stem ball valve can be directly buried under ground without building a high and large valve well, which greatly saves the construction cost and engineering time. The length of the valve body and the height of the valve stem can be adjusted according to the construction and design requirements of the pipeline. The machining accuracy of the ball is very precise, the operation is light, and there is no bad interference.The extended stem ball valve is composed of a fully welded valve body and a carbon reinforced fluorocarbon gasket, which can operate for a long time under the condition of frequent operation, impurities and chemicals. The grinding fine stainless steel ball can ensure the opening and closing freely for many years, and the operation is reliable. The floating seat structure is adopted, and the inclined surface elasticity ensures that the sealing ring is tightly pressed on the ball, even in the case of unstable pressure, the valve can be tight sealed. The anti leakage structure of the valve stem uses two "O" rings to make the valve stem rotate freely and seal tightly. Compared with the same size of the bolted trunnion ball valve, the valve body is small and beautiful. The fully welded body can prevent the danger of gas accident, so is a very safe valve. When the operate the underground ball valve, the operator does not need to enter the underground, can operate the valve above the ground through the extended stem and actuator, which is very safe and convenient.Product advantages: 1. The valve stem can be lengthened according to the user's specific installation conditions to facilitate ground operation.2. Compared with the conventional ball valve of the same specification, it has the advantages of small volume, light weight, beautiful appearance, durability, etc.3. The sealing surface materials of valve seat can be PTFE, Nylon, Alloy steel, hard alloy, etc. according to the different medium, different temperature, pressure and corrosive requirements.4. The valve body is connected by welding fully, and the valve can be welded to the pipeline directly. So there is no possibility for external leakage.Application: City gas: gas output pipeline, main line and branch supply pipeline, etc.Central heating: output pipeline, trunk line and branch line of large heating equipment. Heat exchanger: opening and closing of pipes and circuits. Iron and steel plant: all kinds of fluid pipes, waste gas selective discharge pipes, gas and heat supply pipes, fuel supply pipes. All kinds of industrial equipment: all kinds of heat treatment pipes, all kinds of industrial gas and thermal pipes.Common Models: WQ367F, WQ367H,WQ367Y, WQ967F, WQ967H, WQ967Y, WQ667F, WQ667N， WQ667H, WQ667YManufacturer: ZIPO VALVE & PUMP CO., LTD
