Valve block K1B0078H8 (full functional analogue of hydraulic pump colector assembly 2658341433 PV 235 (R901186977 Rex

Valve block K1B0078N8 is a valve-type directional control valve with flange connection to the pump unit of 2658341433 pumping unit of the PV 235 series drilling rig from Atlas Copco Drilling Solutions, i.e. it is a functional analogue of the Rexroth block R901186977. The K1B0078H8 valve block is designed to change the direction of fluid flow in the closed circuit system of the drilling rig. Valve block K1B0078H8 maintains the set normative parameters of working fluid for the closed circuit pump and provides switching of fluid flow from the drilling rig rotation system to the starboard running system. Field of application - closed circuit hydraulic drive of rotary drilling rigs. Valve block (diverter) K1B0078H8 with a nominal flow rate of 900 l/min and a maximum pressure of 315 bar flange mounting to the pump for closed circuit 2657799322 P6V P7V P6s P8V P6-P7 P8 Parker Denison.
