Required Motor hp: 1/2
• Minimum flow rate of 0.06 gph can be achieved at a Manual Dial setting of 0.1.
• Flow rates above 8 gph are not guaranteed to meet API 675 Performance Standards.
• Only use motors 1/2 hp with turndown ratios to match the appropriate range of application.
Required Motor kW: 0.37
• Minimum flow rate of 0.227 lph can be achieved at a Manual Dial setting of 0.1.
• Flow rates above 30.28 lph are not guaranteed to meet API 675 Performance Standards.
• Only use motors 0.37 kW with turndown ratios to match the appropriate range of application.
