型号ZW221/ZW222水位控制阀根据相对压力精确控制储水罐或蓄水池内的水面位置，无需浮球和传感器。基本特征是容易维护和维修，并为用户提供最低的使用寿命全程成本。
The ZW221/ZW222 Altitude Level Control Valves accurately control water level in a tank or reservoir based on relative pressure, without the need for floats and sensors. Standard features ease maintenance and repair to provide the lowest ownership costs.
- 型号ZW221单路水位控制阀控制储水罐或蓄水池内的水面位置
ZW221 One Way Altitude Level Control Valve controls water level in a tank or reservoir - 型号ZW222双路水位控制阀在控制水面位置的同时，还允许回流，所以在储水罐／蓄水池内仅需要一条管道。当上游供水压力下降到低于罐内压力时，主阀开启。
ZW222 Two Way Valve controls water level while also allowing reverse flow, so only one line is needed to the tank/reservoir. When upstream supply pressure drops below tank pressure, main valve opens - 根据相对压力原理精确控制水位，无需浮球和传感器
Accurately controls water level based on relative pressure, without the need for floats and sensors - 标准配置环氧树脂涂覆和不锈钢编织软管引导系统，耐腐蚀，且简化引导系统的维修
Epoxy coating and stainless steel braided hoses on pilotry come standard for corrosion resistance and simplified pilotry repairs - 可提供150磅级法兰、300磅级法兰、沟槽和螺纹等多种连接端口，适用于各种安装需求
150 class flanged, 300 class flanged, grooved, and threaded end connections available for installation versatility - 可提供截止阀、缩径截止阀和角阀等阀体结构
Globe, reduced port globe, and angle bodies available - 标准阀门配置单点设置 ——开启阀门向储水罐内注水，当到达设置的最高水位时关紧阀门
Standard valves come with one set point – the valve opens to fill the tank and will close drip-tight once the high water level is reached - 可调节范围从5英尺至230英尺
Adjustment ranges available from 5’ to 230’ - 型号D延迟开启／双设置点备选件，当水位到达较低设置点时延时开启阀门
"D" Delayed Opening/Dual Set Point Option delays opening of valve until water reaches a lower set point
