- Page 83 SEAL KIT AND SAFE USE RECOMMENDATIONS The normal mechanical life of a Maxton valve is in excess of two million cycles. Valve operating life can be affected by many variables, i.e. the operating temperature, the usage frequency, the pressure ratio, and the presence of contaminants in the oil, their size, type and amount, etc. With the presence of at least some adverse conditions in most installations, serious consideration should be given to overhaul or replacement of a control valve on a five year cycle.

- Page 90 BV3-4 2.640 Maxton Bleed Port's are machined parts with black oxide finish designed to aid in the bleeding of air from the jack during installation, oil replacement, or other repairs where unwanted air might enter the jack. No more oil showers or worn out threads in the jack when typical pipe drain plugs were used.
- Page 91 INTERLOCK HYDRAULIC VALVE (UNINTENDED MOVEMENT) Introduction 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.
- Page 92 INTERLOCK HYDRAULIC VALVE (UNINTENDED MOVEMENT) ILV COIL OPERATING SEQUENCE Energize when a down call is registered along with down solenoid Coils ( D & DL) to allow down flow. De-Energize to stop. MANUAL LOWERING Open main valve manual lowering first. On Interlock Valve, push ML Button to lower car downward at leveling speed when necessary.

- Page 95 The TA4M is a complete portable Hydraulic Elevator Simulator with automatic controls. It is used for adjustment training for Maxton UC4 and UC4M control valves. With this simulator, installation and service technicians can be easily trained in a class room environment to setup these Maxton control valves utilizing the same control features as a commercial elevator.
- Page 96 Pressure Switch Normally Open (PSNO-2) Complies with ASME A17.1 / CSA B44 The Maxton Pressure Switch (PSNO-2) has been tested specifically for hydraulic elevator applications. The switch has been pre-set for a fast and accurate response in a low-pressure activation and can be mounted directly to all Maxton control valves.
- Page 97 ISOLATION COUPLINGS The Maxton Isolation Coupling's are comprised of two pipe flanges coupled by a threaded retainer ring. This design has increased strength and reduced weight at a lower cost. The threaded ring design provides superior strength because of the consistent sealing torque around the Thermoplastic Seal.
- Page 98 Non-Clean System Definition – This is an elevator system in use without an oil filtration device. Maxton recommends installing the TDF and running the pump (no coils energized) for several minutes to filter the oil in the system.
- Page 99 Maxton 2" to 3/4" Port Adapter Flange was designed for Residential/LULA or low flow hydraulic elevator applications using the UC4, UC4M Series of Maxton Valves. These easy to install flanges use a seal ring design to insure proper sealing of the 2" side against the Maxton valve while the 3/4"...
