一、概述Outline：

ZMAS精小型氣動薄膜角形單座調節閥采用頂部導向結構，配用多彈簧執行機構，具有結構緊湊、重量輕、動作靈敏、流體通道呈S流線型、壓降損失小、閥容量大、流量特性精確、拆裝方便等優點。廣泛應用于精確控制氣體、液體等介質的工藝參數如壓力、流量、溫度、液位保持在給定值。特別適用于允許泄漏量小，閥前閥后壓差小的高粘度，含有懸浮物和顆粒狀物質流體的調節，可避免結焦、堵塞、便于自凈與清洗的場合。

本系列產品有標準型、調節切斷型、波紋管密封型、夾套保溫型等多種品種。產品公稱壓力等級有1.6、4.0、6.4MPa，公稱通徑范圍DN20-200mm。zui小閥芯口徑3mm，適用流體溫度有-200~ 450。允許泄漏量等級有IV級和VI級，流量特性為線性或等百分比。

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.
