CW系列单向阀
结构特点STRUCTURAL FEATURES：
全焊接结构提供牢固可靠的流体系统控制能力 Fully welded structure provides solid and reliable fluid system control capability
当压差不到2PSIG（0.14bar）时，阀门即可产生正向流动 When the pressure difference is less than 2PSIG (0.14bar), the valve can generate forward flow
当背压5～10PSIG（0.34～0.69bar）时，阀即可关闭 When the back pressure is 5-10PSIG (0.34-0.69bar), the valve can be closed
合金弹性元件提供持久弹性，提高阀门使用寿命 Alloy elastic components provide long-lasting elasticity and improve valve service life
