Barnabas is from Pakistan, and has cooperated with AAK for 4 years. Some time ago, he contacted me and needed my help to customize a 1+1=1 hydraulic threaded cartridge valve. They have a hydraulic manifold developed by themselves. The customer feels that the manifold is too complex in the selection of cartridge valves. Their engineers asked to integrate the functions of the hydraulic relief valve and flow control valve into a hydraulic threaded cartridge valve. The cartridge valves in the manifold are all standard parts from HydraForce. For multi-functional hydraulic threaded cartridge valves, HydraForce has no time to customize it.

 

After discussion, AAK engineers decided that it is feasible to combine the functions of relief valve and flow control valve into a hydraulic threaded cartridge valve. After 45 days, AAK sent 20 hydraulic threaded cartridge valves. Last week, Barnabas sent an email asking me to prepare the production plan of 500 hydraulic threaded cartridge valves in advance. Their manifold was recognized by customers. Their engineers were satisfied with the dual-function of AAK hydraulic threaded cartridge valves.

 

AAK hydraulic threaded cartridge valve can not only adjust the system pressure, but also realize the easy unloading of the oil circuit when the multi-way valve stops working. Our engineers have made 3 innovations, which most cartridge valve manufacturers can hardly think of at the same time.

 

1. Change of valve spool: there are pilot valve spool and main valve spool, and there are 3 through grooves connected in turn. The main valve spool is at the front end of the pilot valve spool, located in the first passage slot, and the length is less than the length of the passage slot. The pilot valve spool is located in the third pass slot, the convex part passes through the second pass slot and extends into the first pass slot, and the convex slope matches the slope of the second pass slot.

 

2. Spring change: there is a main spring in the main valve spool. One end of the spring is against the main valve spool and the other end is against the valve housing. The outer side of the pilot valve spool is sleeved with a pilot spring. One end of the spring is against the bulge at the front end of the pilot valve spool, and the other end is against the locking structure at the rear end of the pilot valve spool.

 

3. Change of through-hole: the valve housing is provided with a first through-hole and a second through-hole. The first through-hole corresponds to the position of the pilot valve spool, and the second through-hole corresponds to the position of the main valve spool. The front end of the main valve spool has a filter pad, the side wall of the main valve spool has a third through hole, the front end of the main valve spool has a fourth through hole, and the filter pad has a fifth through hole.

 

The optimized hydraulic threaded cartridge valve, when the multi-way valve stops working, the pilot valve spool moves towards the main valve spool, and the main valve spool moves towards the front end, so that the second through hole corresponds to the third through hole. The hydraulic oil passes through four through holes, replacing the functions of relief valve and flow control valve, and realizing unloading.

 

AAK hydraulic threaded cartridge valve, replaces the relief valve and flow control valve, with 2 in 1, save you money. Welcome to have a try!
