Purros Machinery Hydro speed regulators are designed to control the forward speed (feed rate) of the Electro Pneumatic Drilling Units. Use of a regulator provides adjustable feed rates, faster cycle times, reduces burring, eliminates drill breakage, and prevents sudden forward surges at drill breakthrough. One regulator is required per Electro Pneumatic Drilling Units for drilling operations.
Even if remove the load of piston rod of R-A type hydraulic damper, the piston rod still can stay at original position, only provide compressed air piston rod can return, a multiple setp feed control can be carried out.
