Operation: Logan SAE PTO’s require a 3-way normally closed operating valve with a system flow rate of 2 gpm (7.5 liters) to ensure proper response time during clutch actuation; (if the solenoid is not activated, fluid will not pass through the valve).
SAE PTO Hydraulic Actuation: A pressure switch must be installed in the inlet line to ensure that a minimum and maximum pressure is available prior to clutch engagement. Pressures exceeding the maximum desired clutch pressure may cause back plate deflection and premature clutch failure.
SAE PTO Clutch models range from 100 psi. to 250 psi pressure. Consult Logan when reviewing which clutch best suits your application. A 20-micron filter element should also be installed in the supply line, before the valve, to minimize excessive dirt, oil and moisture.
SAE PTO Pneumatic Operation: Logan SAE PTO’s require a 3-way normally closed operating valve to function properly, (if the solenoid is not activated, air will not pass through the valve). A pressure switch must be installed in the inlet line to ensure that a minimum of 100 psi (6.8 bar) is available prior to clutch engagement. A 20-micron filter element should also be installed before the switch to minimize excessive dirt, oil and moisture. If an air source is not readily available on your equipment, Logan suggests using an air compressor capable of producing 0.14 SCFM at 100 psi (6.8 bar).
The Logan Hydraulic or Pneumatic Start-up kits are designed to simplify Logan clutch installation and to ensure reliable and accurate engagement of the Logan PTO. Pneumatic Valving: Logan offers a solenoid activated, normally closed, 3-way directional control valve with a 3/64” inlet and outlet port. Valves are available in 12 or 24 volt DC.
Hydraulic Power Packs (HPU’s): For vehicles that are not equipped with an air or fluid source, Logan does offer power pack kit options. Consult Logan factory for more details.
Logan offers fluid and air actuated valve manifolds complete with gauge and pressure switch to ensure reliable and accurate engagement of the Logan PTO
Logan Hydraulic Power Packs are available for machines not equipped with a fluid source, and can be operated by a 12 or 24 VDC power supply.
