气动薄膜角形单座调节阀

概述Outline：

ZMAS精小型气动薄膜角形单座调节阀采用顶部导向结构，配用多弹簧执行机构，具有结构紧凑、重量轻、动作灵敏、流体通道呈S流线型、压降损失小、阀容量大、流量特性精确、拆装方便等优点。广泛应用于精确控制气体、液体等介质的工艺参数如压力、流量、温度、液位保持在给定值。特别适用于允许泄漏量小，阀前阀后压差小的高粘度，含有悬浮物和颗粒状物质流体的调节，可避免结焦、堵塞、便于自净与清洗的场合。

本系列产品有标准型、调节切断型、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1.6、4.0、6.4MPa，公称通径范围DN20-200mm。zui小阀芯口径3mm，适用流体温度有-200~ 450。允许泄漏量等级有IV级和VI级，流量特性为线性或等百分比。

ZMAS fine small single-seat pneumatic control valve film angular orientation using top of the structure, equipped with multi-spring actuator, with a compact, light weight, sensitive, fluid channel was streamlined S, the pressure drop loss, valve capacity, flow characteristics accurate, and easy disassembly. Widely used for precise control of gases, liquids and other media of process parameters such as pressure, flow, temperature, liquid level maintained at a given value. Especially for a small amount of allowable leakage, the valve before the valve after the pressure difference of the high viscosity, particulate matter containing suspended solids and fluid regulation, to avoid coking, plug, easy to self-purification and cleaning of the occasion.

This series of products are standard, adjust the cut-off, bellows seal type, jacket insulation type and other species. Product nominal pressure rank has 1.6,4.0,6.4 MPa, nominal diameter range of DN20-200mm. Minimum spool diameter 3mm, apply the fluid temperature -200 to 450. Allowable leakage levels are Class IV and Class VI, flow characteristics of linear or equal percentage.
