Y696VR Series vacuum regulators are used where a decrease in vacuum must be limited, such as between a tank and vacuum source to control vacuum in a tank. A decrease in vacuum (increase in absolute pressure) on the diaphragm moves the disk away from the seat, allowing a higher vacuum source to return the system to the setpoint. Y696VR 系列真空调压器用于必须限制真空压降的情况,例如在储罐与真空源之间用于控制储罐内的真空。 阀膜上的真空压降(**压力增加)会将阀瓣从阀座上移开,以让更高的真空源使系统恢复至设置点。 咨询电话零贰零-捌贰壹柒捌柒伍叁 134*2361*0804刘小姐 Features Precision Control of Low-Pressure Settings Corrosion Resistance Installation Adaptability Wide Material Selection High Capacity Feature 6 Feature 7 Feature 8 功能 精确控制低压设置 耐腐蚀 安装灵活 广泛材料选择 高流通能力 特性 6 特性 7 特性 8 Specifications Body Sizes and End Connection Styles Cast Iron: 1-1/2 or 2 NPT Steel or Stainless Steel: NPS 1-1/2 or 2 / DN 40 or 50, NPT, SWE, CL150 RF, CL300 RF or PN 16/25/40 Hastelloy C: NPS 1-1/2 or 2 / DN 40 or 50, NPT or CL150 RF Maximum Control Pressure Full Vacuum Maximum Downstream Pressure Full Vacuum Vacuum Control Pressure Ranges 1-inch w.c. to 3 psig / 2 mbar to 0,21 bar in six ranges Pressure Registration Type Y696VR: Internal Type Y696VRM: External Temperature Capabilities NBR: -40° to 180°F / -40° to 82°C FKM: 40° to 300°F / 4° to 149°C FFKM: 0° to 300°F / -18° to 149°C EPDM: -20° to 275°F / -29° to 135°C VMQ: -40° to 300°F / -40° to 149°C 规格 阀体尺寸和端面连接方式 铸铁:1-1/2 或 2 NPT 钢或不锈钢:NPS 1-1/2 或 2 / DN 40 或 50、NPT、SWE、CL150 RF、CL300 RF 或 PN 16/25/40 哈氏合金 C:NPS 1-1/2 或 2 / DN 40 或 50、NPT 或 CL150 RF 较大控制压力 全真空 较大下游压力 全真空 真空控制压力范围 1 in. w.c. 至 3 psig / 2 mbar 至 0.21 bar,六个范围 取压方式 Y696VR 型:内取压 Y696VRM:外取压 温度适用范围 NBR:-40° 至 180°F / -40° 至 82°C FKM:40° 至 300°F / 4° 至 149°C FFKM:0° 至 300°F / -18° 至 149°C EPDM:-20° 至 275°F / -29° 至 135°C VMQ:-40° 至 300°F / -40° 至 149°C 广州奥丽斯特燃气设备有限公司
