Electro-Hydraulic Cylinder

Electrohydraulic cylinders are actuation devices that use pressurized hydraulic fluid to produce linear motion and force. A hydraulic pump is an integral part of the cylinder design. Electrohydraulic cylinders use a combination of fluid power components, valves, and electronic controls such as a transducer to provide rod position feedback and to ensure efficient machine operations.

Electrohydraulic cylinders are comprised of linear actuators that are used to control valves in a variety of pumps, compressors, and in steam turbines that are used in hydropower generation. An electrohydraulic actuator is combined with a pilot valve, power cylinder, and electronic feedback component and is designed to operate in mechanically-driven or generator-driven steam turbines. An electro hydraulic actuator may be used for linear or rotary applications. Advances in transducers and the logic used to program them makes electrohydraulic systems highly accurate, efficient, and precise because of the feedback control system built in to the electrohydraulic cylinder. Electrohydraulic actuators are controlled by a variety of components, such as linear transducers for sensing rod position; hydraulic amplifiers to amplify the motion of a stepper motor; and rotary encoders which translate piston motion in to ball screw rotation. This flexibility enables electrohydraulic cylinders to be used as custom cylinders on machine tools and for precision motion control applications

Electrohydraulic cylinders are also used as components for an electrohydraulic control system, for speed, pressure and flow applications. Electrohydraulic control systems are used in steel and rolling mills, shipbuilding and offshore drilling applications, materials handling, wood products processing, and many general mechanical engineering applications. Electrohydraulic cylinders are also designed for use in brake systems where the electronic feedback control can replace the traditional mechanical linkage system

Position sensing and feedback devices enhance the functionality and productivity of a hydraulic system. At its simplest, a cylinder extends and retracts until it meets a physical obstacle or reaches the end of its stroke. The addition of controlling electronics allows the system designer to regulate velocity and acceleration, and to link associated processes to points in the cylinder's cycle. The resulting system combines the flexibility of electronic control with the unmatched power density of hydraulics, benefitting both the designer and end user.

Mounting Brackets

We design, manufacture, supply & commission the total system and take turnkey contracts. The cylinder mounting brackets & frames are designed to meet the site requirement.

Hydraulic Power pack

With demand from our customers for total system requirement for specific applications, we today take up powerpack manufacturing. We have a dedicated specialised team which caters this demand.

High end application power pack with servo-controls or proportional controls along with total system integration is our speciality. Power packs also sometime come up with a need of system oil temperature control mechanism and remote control panels using high end communication protocols and codes. Petroleum industry requirements are also catered by us, where explosion proof protection class components are only to be used.

Gland Kits

Hydraulic cylinder gland service cartridge kits contain a replacement gland fitted with standard wiper and rod seals, plus a gland/head O-ring seal. Supplied ready to fit, gland service cartridge kits reduce machine downtime and avoid the risk of seal damage during installation of seals into the gland grooves.

Piston Kits

Hydraulic cylinder piston service kits contain a full set of piston seals, plus replacement body end seals. We manufactured to the original specification and guaranteed to fit precisely, minimise machine downtime, restore performance and match the long service life of the original parts.
