SHANGHAI GOFLOW MOYER FLUID TECH CO., LTD. 使用本控制阀时，请先仔细认真阅读和理解本说明书，通过正确的使用和维护，充分发挥 其效能。 Before using this control valve, please read and understand this specification carefully. Fully display this function through the correct use and maintenance. 平衡式气动截止阀 平衡式气动截止阀是我公司自行研发，本型号产品总结了多年生产经验和用户实际应用情况，而 设计的新一代冶金专用型平衡式截止阀。该平衡式气动截止阀上装有阀杆导向环，能有效的自清洁附粘 在阀杆上的粘性介质，防止阀杆在运动过程中因阀杆上的附粘物而刮伤填料，造成介质外泄，有效的提 高了阀门使用寿命。阀芯采用笼式平衡阀芯结构，能有效的减少阀芯启闭力，启闭轻松省力、噪音低、 防冲蚀、在任何压差下可保证启闭自如。阀体流道呈 S 型，特点是压降损失小、流量大、动态稳定性 好、噪音低。 平衡式气动截止阀为许多苛刻工况的可靠切断提供了可能，其阀芯堆焊硬质合金后经过专用设备 的研磨和硬化处理，具有很高的机械强度和耐磨性，同时具有可靠的密封性，特别是粘性介质和介质含 有粉尘重等工况，选择了平衡式气动截止阀也就是选择了长寿命的可靠切断阀。 该系列截止阀也可以制成波纹管密封型、加长型上阀盖等特殊结构。 截止阀可根据用户要求，配用气缸执行机构、电动执行机构、液动执行机构、电液联动等执行机构， 其结构紧凑、外形美观。 Balanced Pneumatic Stop Valve The balanced pneumatic stop valve is the product independently produced by our company. This product is the newly metallurgy special balanced stop valve based on the experiences and practical usage application. The stem guide ring equipped in the balanced pneumatic stop valve is able to effectively eliminate the viscous medium sticking to the stem to prevent the sticking material in the stem from scrapping the fillings to result in medium leakage and effectively improve the valve usage lifespan. The valve plug is using the balanced plug structure to effectively reduce the opening and closing powers of valve plug and ensure the convenient start and close in any pressure due to low noise and erosion resistance. The valve body runner is in shape of S with the features of low loss of pressure reduction, large flow, sound dynamic stability and less noise. The balance pneumatic stop valve has provided many possibilities for the server working conditions. The surfaced hard alloy of valve plug is of high mechanical stre
