#CMT# #/CMT# The effective proportion of the second control area (D) subjected to pressure from the inlet connection (A), decreases with increasing opening cross section. Pilot control valve (5) construction is such that the control pressure is a given fraction of the pressure acting in the inlet connection (A). The main step (3) surrounding the control piston (7) is constructed as a built-in, 2/2 way valve. The inlet connection (A), discharges into a bore (25) for flow. This is coaxial with the axis of control piston (7) movement. #CMT#USE : #/CMT# A pilot-controlled directional valve for controlling larger flows of hydraulic fluid. #CMT#ADVANTAGE : #/CMT# A new, simplified design is offered. Manufacturing costs are saved. Extensive precision machining of the closure piston, to prepare the necessary channels and control edges for the supply throttle, is avoided. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic cross section of the valve. 3 : main step 5 : pilot control valve 7 : control piston 25 : bore for flow A : inlet connection D : second control area. |
