2、KCMF1218 Valve of DS Dynatec modification service

In May, 2011, one of our customer ordered 13pcs of KCMF1218 valves of DSD brand.

In May 2011, when system debugging, the valve core kept vibrating as the testing pressure is 0.4-1bar by nitrogen, and the valve could not be open if the pressure up to 5bar.

Because the customer’s special on-site technology cannot be changed-- there is 10cm throttle orifice behind the valve, which can reduce the pressure differential, the former straight-pilot valve KCMF1218-2 must be changed to force pilot operated valve KBMF1218-2. And after contacting with DS Dynatec on Nov. 25, 2011, it’s confirmed to change to KBMF1218-2 valves. For this problem, DS Dynatec replied quickly, and on the same day, we reached a solution, before Dec. 10, 2011, DS Dynatec would send the replacements to us.

And our reply to the customer was that as soon as we got the replacements, we will arrange after-sales man to go to Beijing to replace the pistons, springs and connections, so as to ensure the valves work.

On Dec. 1st,2011, the DSD replacements were sent out from France, and on 12th, they arrived Dalian. And on 13th, we tested the replacements in the workshop,0-12bar,test OK. And on Jan. 15th,2012, the replacements are put in storage waiting for the customer’s notification for on-site debugging and replacement.

In Feb. 2012, we sent the after-sales man to Beijing for on-site replacing and testing. So we provided a reasonable solution for the customer for the special technology valves.
