But our basic intention was never to be a Jack of all and master of none. We have always kept our design & development on their toes, even when a product has been positively accepted in the market, we have made changes for the better instead of resting on our laurels.
All the time of inception, our aim is in the field of Landing Valves, Hose Coupling, Hose pipe etc. (Iron such as and Valves) Every effort was made to adhere to the relevant National and International Standards.
The company emphasize on Quality Assurance and Design Parameter. It is proud of the company to set up a Computer Aided Design (CAD) System. The Company has on its rolls well experienced and Qualified Engineers heading the Departments of Design, Quality Assurance & Production with dedicated team of Technical Staff working under them.
ESSEL VALVES PVT. LTD. has its own foundries. A brief details for the various units are as under;
Quality assurance is ensured by a written assurance program that include the following testing and inspection procedure:
Chemicals - by a spectra meter
Mechanical - by UTM
Materials - Gunmetal, Brass, Stainless Steel, Aluminum, Cast Iron
"ESSEL VALVES PRIVATE LIMITED HAS AIM TO SATISFY IT'S CUSTOMERS BY MANUFACTURING AND SUPPLYING OF ALL PRODUCTS OF COMMITTED QUALITY AT COMPETITIVE PRICES, WITH PROMPT SERVICES"
ESSEL VALVES PVT. LTD. is the manufacturer of Fire Fighting Equipments, Our range includes a wide range of products, mainly for application in Hydrant Systems.
All Products are manufactured in accordance with the guidelines set by Indian standards and International Standards.
In the manufacturing process we require gun metal and brass ingots, steel casting of various grades, stainless steel round bars, forging, hardware (nuts & bolts), gaskets, paints and also packing materials. We purchase all the raw materials from the approved suppliers.
All raw materials are checked by our Internal Quality Assurance Department prior to infusion into the manufacturing process. For example, when we receive steel castings and rods, it is checked and then poised on to stores with an "INWARD PASSED" sign and stamp, if it is rejected it is sent back to the supplier with a G.I.R. note.
The raw materials is issued to the machine shop for machining through material requisition slips. valve body, bonnet, valve seat, spindles etc. are machined on CNC machine after which all the components are checked by vernier callipers or micrometers.
If it is found to be OK dimensionally and visually, the valve body and bonnet are sent for hydrostatic Testing to the testing yard and other components are sent to the fitting / assembling department. All the bodies and bonnets are tested on Motorised Hydrostatic Pumps or on Hand Operated Pumps. A pressure test is carried out as per relevant world standards. The theory being, when the body or bonnet is under pressure there should not be any leakage or drops of the testing and fluid from any portion of the bodies and bonnets. If there is any leakage observed, it is rejected and sent back to the foundrie.
The body and bonnet which are hydrostatically OK are sent to the fitting shop for assembly, duly handled with care so that there are no scratches on the machine surfaces. In the fitting shop, body and bonnets are drilled on drill machine with the help of jigs and fixtures for uniformity and interchangeability by Quality Assurance Department and passed, or sent back.
After assembly the new complete valve, is sent for hydrostatic testing again. If no leakage is observed, as per the relevant standards, it is sent to the finishing department.
Here the valve body surface is debarred and finished by sanders and flexible shaft grinders for better appearance and smooth finishing. One coat of corrosion resistant primer (Red Oxide) is sprayed, and if any uneven surface is observed a high temperature putty is used, after that valves are sprayed pored in colour. They are offered for inspection by the concerned inspectors without Paint, but in a completely assembled stage. After inspection and punched painting is done.
After painting, final inspection is done by our Quality Assurance Department / Third Party Inspection Agency, whose responsibility now is to co-relate and check all records relating to the valve concerned. Special attention is paid to co-relate all the serial numbers and in-process quality checks, a valve serial number and then passed on to the packing department.
In the packing department all the valves are covered with polythene bags and placed into corrugated box with a bed of grass for non-damage of valves. It is then covered and nailed with a packing note.
