MECHANICAL IMPROVEMENTS NEW POWER ACTUATOR PA G2 NEW VALVE BOX We have made the coupling both smaller and lighter. The mechanics have been improved with steel signal pins and an entirely new design for a second lock that both saves space and provides more reliable operation. The new generation power actuator is significantly smaller and provides more space for the bodybuilder, especially with central installation. The new design lowers the risk of air leakage and has improved protection for the second lock. The newly designed valve box in robust lightweight material, with push-in nipples and reinforced hinges, can easily be mounted in different directions. The knob is also easy to operate when wearing gloves.
