I developed the idea of a double-acting
ball screw, that is, one ball screw with a right-handed and left-handed thread, and patented it in 2000.
This new Masoneilan positioner is certified by the Fieldbus FOUNDATION and can be mounted on double-acting
actuators of any manufacturer.
hydraulic Power Pak unit for double-acting
cylinders operates on 12 or 24V, with a flow rate of 1/4 gpm (0.
The column-style presses feature a double-acting
hydraulic cylinder and adjustable daylight.
Other benefits of the maintenance-free, double-acting
element include selflocking wedge clamping, reclamping with hydraulic pressure, high clamping safety in case of sudden pressure drop, cushioning of vibrations and a variety of mounting options.
press has movable upper and lower platens to improve the balance of flow in the mold.
elements are available with or without a self-locking mechanism, with maximum operating pressures of 1,450 or 2,300 psi.
They also feature integral hydraulic systems and a double-acting
cylinder for powered opening and closing.
Vertical stainless steel actuators are offered in double-acting
and spring return for use on all Bradford butterfly valves.
A distinguishing feature of the DeltaRim machines is the use of double-acting
, hydraulically driven piston pumps that can process high-viscosity materials (up to at least 18,000 cp), filled and abrasive systems, polyurea, and other multiple-component systems.
The column-style press features opposed, double-acting
compaction cylinders, one operating from the top of the press, the other operating from the bottom of the press.
The process utilizes a double-acting
piston pumping system, providing precise control of the liquid [CO.
