In fact, this constant cycling of the system is highly undesirable as it greatly reduces the lifespan of the equipment, resulting in higher maintenance costs and more vehicle down time while it is being serviced or repaired. Our network of distributors has been carefully selected to provide customers across the USA & Canada with the additional support they sometimes need. ISRI air valve seat for 6800 AIR seats fitted to DAF, SCANIA, ERF. These have built in slide rails on them for forward and backward positioning. These and other objects of the invention are achieved by minimizing the air losses of the air suspension system during normal operation. Cross References: SK165305, 515-SK165305, SK146701, NTSSK146701, 5828-SK146701, 2586418C91, NSSK146701, NTSSK146701, 85105864. The air restriction valve is actuated by various control inputs which may be derived from any onboard vehicle data sensing system, which may include, but is not limited to, for instance, an automatic braking system signal, an electronic braking system signal, a signal from a motion sensor, an operator input, any other signal that may be generated by an onboard vehicle data sensing system, or combinations of the forgoing. SUMMARY OF THE INVENTION. Adjustable headrests. Light Brackets, Grilles And Channeling. Sears 5500 Series Air Seat Replacement Push-Pull Valve / Switch. The air suspension system 10 is provided with a pressurized air source 12 that is fluidly coupled to height control valve 14. 3, it is contemplated that any number of these may be utilized depending upon the vehicle configuration and the desired vehicle control scheme. Added to Your Shopping Cart. International Truck 337-090-CNP Air Seat Control Valve Aftermarket Replacement.
6 is a piping diagram according to FIG. Application: - Freightliner Cascadia (2012-present). Valves to operate air seat systems including height and lumbar controls. Height & Lumbar Control Seat Valve. Once a measured value of the vehicle height is obtained, the system determines if the vehicle height matches the selected height 70. The air suspension system will cycle less often, which will result in less wear on the system, and will reduce the costs involved with running the system. Spring-loaded, three-way function. Height control valves 34 and 36 further comprise inlet ports 33 and 39, that fluidly couple height control valves 34 and 36 to air restriction valves 38 and 40, respectively.
For instance, in semi-tracker/trailer truck rigs, the specified height is the distance between the vehicle frame and the axle. The system also comprises a first control input for controlling the height control valve, the first control input based on a first parameter, and a second control input for controlling the air restriction valve, the second control input based on a second parameter, the second parameter being different from the first parameter. The measured value is compared with a selected reference value to determine whether it is greater than, less than or equal to the selected reference value.

Control input 20 may also comprise a Time Measurement signal 22, which may include for instance, a measured elapsed time from a specified event or system activation. If it is determined that the air restriction valve 16 has been activated, then the system loops back to measure vehicle height 60 and will continue this cycle until interrupted or the system determines that air restriction valve 16 has not been activated. Ask one of our experts.
Adjustments can be made while seated. Removable chrome knob. It is further contemplated that no particular order is critical in the analysis of onboard data and/or control signals corresponding to the control input. Freightliner Collision. Peterbilt Exterior Parts. Although a number of various control inputs have been illustrated and discussed in connection with control input 20, as has been previously stated, any number of various onboard vehicle data system inputs may be utilized to control air restriction valve 16. Air seat control valve. These come with no adjustment valves to raise and lower the seating position. The dealer wants $40 per valve to sell me valves, but he said I could probably do better elsewhere to buy these parts. Pull: Vents outlet port. Control input 20 may still further comprise a height measurement signal 24, which may for instance, be a measurement of the height of the vehicle frame, trailing arm or any other portion of the vehicle. Truck Wiring And Electrical. In this case, it is important that the air suspension system adjust the air spring to maintain the selected height.
Mack Exterior Parts. License Plate Lighting. Control input 20 may comprise, for instance, but is not limited to, a Braking System signal 21, which may include, for instance, a signal form an Anti-Lock Braking System (ABS), a Traction Control System (ASR), or an integrated Coupling Force Control (CFC). In order to increase the distance from the vehicle frame and the axle, the height control valve opens fluid communication between the inlet port and the air spring port, thereby allowing pressurized air from the pressurized air source to enter the air spring through the control valve. For more information go to (CA Health and Safety Code Section 25249. Air ride seat control valve for 2005. Note: Primary seat application: Bostrom; valve is universal and suitable for a variety of applications. Enter your email: Remembered your password?
For instance, air restriction valve 16 may be plumbed into the air line and be physically separated from both height control valve 14 and air spring 18 as illustrated in FIG. MOST ITEMS ORDERED HERE ARE THEREFORE SHIPPED NEXT DAY DELIVERY. Leakage: When the valve is in "OFF" position it cannot leak to the output port. If the measured vehicle height matches the selected vehicle height such that there is no deviation, the system loops back to measure the vehicle height 60 and will continue this cycle until interrupted or a measured value does not match the selected value. Universal Exhaust Components. ITPD&PMITEM=09249103&PMCTLG=00. Our customer service team will review your requirements and come back to you with a full quotation. When the air spring is at a selected height, the valve is in a neutral position, such that the air spring port is isolated from both the inlet port and the exhaust port. The system is provided such that the first parameter comprises a measured vehicle height and the second parameter is selected to control the air restriction valve such that air losses in the air suspension control system are minimized.
