Installation and maintenance of heat shut-off valve should note the following: hand wheel, lever operated bellows shut-off valve can be installed in any position on the pipeline. Hand wheels, handles and Wei actuator, the valve does not allow for lifting use. The flow of media should be consistent with the direction of the arrow body. Shandong Everbright Valve Co., Ltd. specializing in the production valve manufacturers, welcomed the new and old customers to inquire, call to order our products! [] Also called cut-off valve gate valve brand, it is the most widely used of a valve! The reason it's popular is due to the opening and closing process ① small friction between the seal faces. ② more durable. ③ opening height is not. ④ easy to manufacture. ⑤ easy maintenance. ⑥ applies not only to the low pressure, also suitable for high pressure. [] The cut-off valve is closed principle is to rely on the valve bar pressure, so the valve sealing surface and the valve seat provides tight fit, to prevent the media circulation. Shut-off valve can only medium-way flow, directional installation. Structural length is greater than the cut-off valve gate, while the fluid resistance, long-term operation, the sealing reliability is not strong. When the insulation off valve is open, Weifang stainless steel valves, valve opening height, the nominal 25% to 30% of the diameter, the flow has reached the maximum, Shandong stainless steel valves, that valve has reached the fully open position. So off fully open position of the valve, the valve stroke should be determined. Types of liquefied gas cutoff valve stem threads are divided by location external thread type, thread type. According to the flow of media points, straight-through, DC type and angle type. Cut-off valve according to the sealing form points, shut-off valve packing and bellows sealed stop valves.
