Operating Technology
Industries Served
Helac’s innovative, sliding-spline technology converts linear piston motion into powerful shaft rotation. Each actuator is comprised of a housing and two moving parts — the central shaft and piston. Helical spline teeth on the shaft engage matching teeth on the piston’s inside diameter. A second set of helical splines on the piston’s outside diameter mesh with the gear in the housing.
The piston is completely bottomed out. Bars indicate starting positions of piston and shaft. The housing with integral gear remains stationary.
When hydraulic pressure is applied to the piston, it moves axially; while the helical gearing causes the piston and shaft to rotate simultaneously. Applying pressure to the opposite port will return the piston and shaft to their original starting positions.

STARTING POSITION
ENDING POSITION
Cantilever MountThe load is mounted to the shaft flange and is supported at only one end of the shaft. Cantilever mounting is not recommended for aerial work platforms or other critical and safety-related applications.
Straddle MountThe load is supported at both ends of the shaft.

Customized Products
Helac Corporation can customize our rotary actuators to meet unique application requirements. Custom engineering can range from slight to complete, and is offered to those customers whose actuator needs match our program requirements.
The upper portion of the bracket is bolted to the shaft flange, the lower portion is bolted to the endcap flange.
The upper portion of the bracket is bolted to the shaft flange. The lower portion is secured either by a tie rod passed through the shaft bore or is bolted to the endcap flange.

Valve ConfigurationsOptional factory mounted counterbalance valves prevent rotation in the event of a hydraulic line failure, control rotation when loads go over center, and protect the actuator against excessive torque loads.
Hydraulic Schematic of Optional Counterbalance Valve
Manufactured from aluminum, the valve blocks are bolted to a flat mounting pad on the actuator housing. Three bolts secure the valve block to the actuator. See specification pages for valve location.
The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ±300 psi (228 bar ±21 bar).
Available on select models only, the actuator has a flat mounting pad machined on the housing with threaded holes to accept the valve mounting bolts. The actuator-to-valve ports have threaded plugs which allow the actuator to be used with or without a valve.
Standard Valve for L30-17 and L30-25 180 Degree ModelsManufactured from aluminum, the valve blocks are bolted to a flat mounting pad on the actuator housing. Three bolts secure the valve block to the actuator. See specification pages for valve location.
The pilot ratio is 3:1. The valves are set to relieve at 3300 psi ±300 psi (228 bar ±21 bar).
Standard Valve for all other L30 Series ActuatorsManufactured from ductile iron, the valve blocks are bolted to a flat mounting pad on the actuator housing, usually over port P1. Factory installed steel tubing connects the valve to port P2. Valve locations and plumbing routing differ among sizes. See specification pages for details.
The pilot ratio is 2.5:1. The valves are set to relieve at 3,625 psi ±360 psi (250 bar ±25 bar).
