Web Guiding Systems

We have been successfully manufacturing, exporting & supplying all types of Hydro – Pneumo Web Aligner, Web Guiding Systems, Hydraulic Power Pack Unit, Line Guiding System, etc. since last 25 years from Ahmedabad, Gujarat, India. We are winner of 3 times National Award and 2 times International Award for Quality manufacturing.

KEW is the most leading manufacturer, exporter & supplier for Web Aligner Units in India. We have the capacity to supply 100-150 units of Web Guiding Systems per month. We have systematic work flow chart & updated technology to produce the machine at very high speed and great perfection. We invite inquiries from machinery manufactures also to purchase the units in bulk orders.

KEW Manufacturers, exports & supplies Web Aligner System with high production output & efficient edge guiding function with more than 8000 installation in place all over India and overseas like Saudi Arabia, UAE, Dubai, Sharjah, South Africa, Nigeria, Ghana, Congo, Kenya, Zambia, Sri Lanka, Bangladesh, Malaysia, Pakistan, Nepal, Russia, Thailand, Indonesia, Brazil, Colombia, Venezuela, Argentina, Mexico, Canada, etc. making us the biggest manufacturer, exporter & supplier of Web Guiding System.

KEW make Hydro–Pneumatic Web Aligner are the Heart of Hydro Pneumatic web guiding system, to automatically guide all type of material of any width, at any speed, under any load. Completely self-contained with an integral air generator for sensor. It is coupled with 3 phase AC motor and Hydraulic pump is also attached on the same shaft which is fitted inside the oil tank filled with Hydraulic oil. The signals from the Air flow sensors are received by spool type proportional servo valve mounted just under polyester diaphragm. Unique design gives extremely narrow dead band & fastest possible response for unexcelled guiding results. The power pack units are available in different models from 0.25 HP to 3 HP to meet any guiding application you may have. In-Built Air Generator avoids use of external air supply.

These units are used to automatically guide all type of flexible materials of any width, at any seed, under any load. Inherent capabilities of this unit assure stable operational at all correcting the web at any speed and loads.

KEW Hydraulic Power Pack units are used to automatically guide all types of flexible materials of any width, at any speed, under any load. Completely self-contained, with an integral air pump, these units eliminate the need for additional air regulators or plant air. Modular construction and sub plate-mounted components provide maximum ease of servicing. Inherent capabilities of KEW Web Guiding System assure stable operation at all correcting speeds and loads. Air Pressure Power Units are available in models from 1/4 H.P. to 3 H.P. to meet any guiding application you may have. Double and triple power units are available incorporating two and three servo valves on the same reservoir to handle multiple guiding applications. A source of power is mandatory in a web guiding system. The Hydraulic Power Pack unit is much more than just an energy source, however, because it normally furnishes modulated power to the actuating devices. It therefore is an amplifier of control signals, as well as a power source In addition to providing hydraulic power for the actuating circuit the power unit produces pneumatic power for the sensors. Sensor supply pressure must remain constant, and the power supply provides this element. Our constant pressure generator produces constant pressure at a given head no pressure regulator is therefore required. Water, oil and scale contamination and other miscellaneous plant air problems are also avoided.

KEW uses one of a series of Web guide pneumatic hydraulic units in most of its systems. These units come in several sizes and a suitable one can be found for any application. Our Pneumo Hydraulic Power Pack Units are perfectly manufactured with optimum air flow and maximum load capacity.

Krishna Engineering Works manufactures, exports & supplies Web Aligner Units with efficient edge guiding function with more than 7000 installation in place all over India and overseas like Saudi Arabia, UAE, Dubai, Sharjah, South Africa, Nigeria, Ghana, Congo, Kenya, Zambia, Sri Lanka, Bangladesh, Malaysia, Pakistan, Nepal, Russia, Thailand, Indonesia, Brazil, Colombia, Venezuela, Argentina, Mexico, Canada, etc.
