The product is very important to use the occasion or the environment is more complicated, stainless steel valves, please try to provide design drawings and detailed parameters, by our Valve Co., Ltd. Shandong Everbright professional engineers for your audit selection. If you have any questions you can call us, we will provide you with the best pre-sales consulting services. Valve Co., Ltd. Shandong Everbright welcome your call! When the heat is turned off valve, the valve opening height, the nominal diameter of 25% to 30%, the flow has reached the maximum, 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. [] Also called cut-off valve gate, is the most widely used of a valve! The reason it's popular, the valve is opened and closed due process ① little friction between the sealing surface. ② more durable. ③ opening height is not. ④ easy to manufacture. ⑤ easy maintenance. ⑥ applies not only to the low-pressure, cast steel valves, 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.
