Internal valve model

internal valve points

valve cylindrical control valve is built in the valve housing and controls piston reciprocation.
accumulator the accumulator compensates for pressure in the hydraulic circuit and prevents pulsation. lt is not usually necessary to refill. use N2 gas only.

function

  • extended piston stroke smoother operation Minimal Repercussion On Carrier
  • improved properties(piston) improved emergency running properties manufactured with high-quality nickel & vanadium alloy steel
  • GB tool exceptional performance and reliability manufactured with high-quality alloy steel
  • back head Power Accumulator
  • lubrication adequate for entire shift reduced wear and tear consistent availability due to extended maintenance intervals
  • cylinder & valve prevents scoring with precision finishing treatment
  • tie rod dynamic screw desing prevents damage
  • accumulator (some models applied) Reduces Irregular Pulse Pressure on hydraulic circuit improved striking power with supply of accumulated gas pressure
