FAW J6P JH6 Cab Height Control Valve 5001250250312

Brand-new cab height control valve (leveling valve / height limiting valve) for FAW Jiefang J6P and JH6 heavy trucks, complete with the adjustable linkage rod, ball joints and rubber bellows boot as shown.

FAW drawing number 5001250250312. The factory label on the valve reads JS00-5001250B with model code LHD05, and the QR traceability tag carries the B91W-C00-A/A variant code – this valve is also cross-listed in the aftermarket as 5001250B91W-C00. All markings are shown in the photos so you can verify against your old part before ordering.

Key Features:
– Controls the air pressure in the cab suspension air bags, keeping the cab level at the standard ride height whether the truck is loaded or empty
– Automatically inflates or exhausts the air bags when cab height changes, and holds pressure in the neutral position
– Built-in damping structure for smooth response, no hunting or continuous charge / exhaust cycling
– Corrosion-protected valve body with standard quick-connect air fittings
– Supplied as a complete assembly: valve + adjustable linkage rod with ball joints + rubber dust boot

Signs of a worn height valve that needs replacement:
– Air leaking continuously from the valve body
– Cab sitting tilted or at the wrong height
– Air bags never stop inflating or deflating (hunting)
– Linkage ball joints loose or sticking

Applications:
– FAW Jiefang J6P, JH6 tractors and trucks – cab air suspension (front suspension crossbeam mounting)
– Aftermarket listings also cross-reference this valve for FAW J7 applications – please compare photos and part number with your old unit

Note: the FAW J6V uses a different front height valve (5001250A86P series) which is not interchangeable with this part. If your valve casting or label reads differently, send us a photo of the nameplate and we will match the correct part.
