hello mr. doug,
Thank you now i understand circuit clearly. Here i found that the purpose of the load sensing valve is to unload the pump during the P-blocked dcv is in neutral position. So it will not help in resolving the shocks, I think the shock is effectively removed by the counterbalance valve at entrance and exit of the cylinder. isn't it? So if i use them with P-T dcv it will not surge, isn't it? What are shock less type valves? They are denoted as S-DSG-***, will it be help in my circuit?
