The Maxton Interlock Hydraulic Valve (ILV) is a solenoid operated, normally closed check valve designed to prevent unintended elevator down movement. The ILV only allows the oil to flow in the down direction when the solenoid coil is energized. Due to its unique design the up flow is unrestricted and does not require power to the solenoid coil. The ILV should be installed adjacent to the main control valve, no adjustments are required. A push button Manual Lowering is provided to lower the hydraulic elevator in case of emergency.
The ILV complies with ASME A17.1/CSA B44
