Rexroth PowerMaster® Treadle Operated Valves (4 Way, 2 and 3 Position)
Aventics PowerMaster® Valve, 4-Way Directional Control
4 Way / 2 & 3 Position 1/4" - 1-1/4" NPTF Solenoid, Air Pilot & Mechanical Operators
TECHNICAL DATA:
Port Sizes: 1/4", 3/8", 1/2", 3/4", 1", 1-1/4" NPTF
Working Pressure:
Media: Air and inert gases (In service higher than 18 cycles per minute or with continuous air flow, a lubricator is recommended.)
Materials:
Treadle Operators
Treadle operators are furnished without a return spring for two-position heel and toe operation. For three-position operation, centering springs are used. The two-position model may also be used as a three-position, closed center combination.
