进口气动薄膜调节阀(德国OLES奥莱斯)

【进口气动薄膜调节阀】详细说明:

动薄膜双座调节阀采用双导向结构，配用多弹簧执行机构，具有结构紧凑、重量轻、动作灵敏、阀容量大、流量特性精确、拆装方便等优点。气动薄膜双座调节阀广泛应用于控制气体、液体、蒸汽等介质，工艺参数加如压力、流量、温度、液位保持在给定值。

气动薄膜双座调节阀特别适用于允许压差较大，而允许泄漏量也较大的不是很清洁的介质场合。

气动薄膜双座调节阀系列产品有标准型、波纹管密封型、夹套保温型等多种品种。产品公称压力等级有PN10、16、40、64；阀体口径范围DN20~200。适用流体温度由-200℃~+560℃，其范围内多种档次。泄漏量标准有II 级或IV级。流量特性为线性或等百分比。多种多样的品种规格可供选择。

The movable film two-seat regulating valve adopts double guiding structure and multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics and convenient disassembly and assembly. Pneumatic film two-seat regulating valve is widely used to control gas, liquid, steam and other media. The process parameters such as pressure, flow rate, temperature and liquid level are kept at a given value.

The pneumatic film two-seat regulating valve is especially suitable for medium with large allowable pressure difference and large allowable leakage.

The series of pneumatic film two-seat regulating valves are standard type, bellows sealing type, jacket insulation type and other varieties. The nominal pressure grades of the products are PN10, 16, 40, 64, and the caliber range of the valve body is DN20-200. The applicable fluid temperature ranges from - 200 C to + 560 C, and there are many grades in the range. Leakage standards are level II or IV. Flow characteristics are linear or equal percentage. Various varieties and specifications are available.

【进口气动薄膜调节阀】特点：

·气动薄膜双座调节阀，工作时稳定性好。

·有两个阀芯和阀座，采用“四通”阀体，可以方便地由正装改装成反装，气关阀变气开阀。

·阀体按流体动力学原理设计的等截面低流阻流道，额定流量系数大。

·不平衡力小，允许使用压差较大。

·执行机构采用多弹簧结构，高度减小30%。重量减轻30%。

·可调范围大，固有可调比为50%。

·波纹管密封型调节阀对移动的阀杆形成了*密封，堵绝流体外漏。

·调节阀带有保温夹套，用于流体冷却后易结晶、凝固造成堵塞的场合。
