2 Introduction Our actory lco Valves Ltd., is a member of the XMOL roup of companies. lco Valves manufacture a wide range of high quality mechanical pipeline and instrumentation products. The ompany operates from a custom built facility in righouse, West Yorkshire, United Kingdom. The factory, Mission Works, was built for the express purpose of manufacturing valves and accessories Mission Works and it's facilities are constantly benefiting from regular capital investments. This ensures that lco is able to manufacture it's products using cutting edge technology, up-to-date internationally recognised engineering methods in the production processes and quality assurance programme. With over 25,000 sq. ft (4,200-sq. m) of workshop and machine shop area, large project work can be easily undertaken. International vailability lco's wide range of products are available direct from the factory sales department or via a network of stocking distributors. lco representatives are available 24 hours a day via the latest communication systems including and the information super highway - the Internet. Our network of distributors offer support to you and your clients world-wide 365 days a year. With our own on the ground assets, partnerships and authorised distributors operating in many countries, lco is there to assist you and your clients globally. lco products can be specified and sourced readily and with local support, wherever you are. Quality ssurance, Safety & eliability S5750 now ISO 9000 Series (since1982) Quality assurance has acted as a cornerstone in the ompany's success and has contributed greatly to lco's world-wide appeal, growth and expansion to date. This is why lco Valves sought and achieved S5750 (now ISO9000 series) as far back as lco Valves saw the need for consistently reliable and safe products for industrial use earlier than most, which is why S5750 & ISO9000 series quality assurance systems were implemented in 1982, far sooner than other mainstream valve manufacturers around the world. The quality assurance system has been maintained and regularly audited by third party authorities and their international counterparts ever since. Timely, high quality production and manufacturing techniques have always been employed by lco to produce precision engineered valve solutions for some of the world's largest companies. lients operating in some of the most inhospitable areas of the world often use lco valves, therefore our high standards and product reliability counts. ue to lco's uncompromising standards of safety, design and reliability, stringent applications at high pressures and temperatures in corrosive environments can be easily dealt with subject to valve design. ll materials used to manufacture the major components are traceable and copies of original mill certificates are retained for future reference.

Viscous media luids with high viscosity. Vital components Valve parts the failure of which would render the valve useless. Viton fluoroelastomer with excellent resistance to petroleum products. Volatile volatile substance is one that is capable of being evaporated or changed to a vapour at a relatively low temperature. Volatile substances also can be partially removed by air stripping. device for determining the viscosity of oil. There are several methods or devices in general use. asically, a fixed quantity of oil is allowed to pass through a fixed orifice at a specified temperature over a measured time span and then compared to a standard liquid such as a calibration oil or water. Measure of the internal friction or resistance of an oil to flow. s the temperature of an oil is increased, its viscosity decreases and it is therefore able to flow more readily. Viscosity is measured on several different scales, including edwood No. 1 at 100, ngler egrees, Saybolt Seconds, etc. The most common method for designation of viscosity is kinematic viscosity, measured in centistokes, 50entigrade.
