4 WLWORTH OMPNY WLWORTH ompany is one of the world s most dominant and comprehensive global industrial valve manufacturers and marketers. Founded in 1842 by James Walworth, the ompany has consistently dedicated itself to the design and manufacture of an array of valves end use industries and comprehensive customer requirements by adhering to the most demanding quality standards. WLWORTH relies on its broad experience in supplying valves to the petrochemical, oil & gas, petroleum, power generation, pulp and paper, cryogenic and geothermal industries, among others. Over the years, the ompany has produced more than 40,000 different types of products and serves as a global supplier to varied markets utilizing the expertise of over 500 trained employees. WLWORTH retains facilities in the United States, Mexico and hina for the complete range The ompany is unrivaled in its total approach to manufacturing. This includes utilization of ompany - directed raw material warehouses, up-to-date specialized machinery, welding processes such as SMW, GMW, SW, PW; and assembly testing for low pressure, high pressure, at low or high temperature, painting process, crating and shipment. With ompany-directed facilities and stocks in the United States and Mexico, WLWORTH is capable of providing the world s most comprehensive industrial valve line to the North merican, entral merican, South merican, European and frican markets. With ompany-owned facilities in hina, Walworth is serving sia, the Middle East, Far East and ustralia, today s fastest growing industrial arena in the world. Walworth is proud to meet the ultimate demands of customer satisfaction, especially in quality, cost effectiveness and services in all parts of the world. WLWORTH VLUES MISSION To satisfy the needs of ustomers in terms of quality and service and comply with expectations of employees, suppliers and share holders. VISION To maintain our good reputation in terms of service, delivery and quality which has been the main goal during all these years that has positioned WLWORTH brand as a reliable ompany for over 167 years in the market. To continue developing new products according to the needs of the market in terms of technology, environment and quality requirements. WLWORTH does manufacture valves, but at the same time gives service to our ustomers. 4

5 WLWORTH ENGINEERING ONTROL WLWORTH products are manufactured following strictly the most recognized international standards all over the world, such as PI, NSI, SME, STM, MSS, NE, WW, SI, S, among others. Our Engineering team is always studying the new updates of these standards to incorporate any changes that may affect the design, regulations or performance of our products, being leaders in the new developments achieved. esign is made using the most advanced technology and ensure the proper assembly and performance of products since the concept, calculation and detailed drawings for manufacturing. WLWORTH is a leader in the development of new products according to valve market current needs. WLWORTH QULITY SYSTEM Throughout the years, WLWORTH has developed its Quality System which is an integral part of our manufacturing policy. Our primary goal is to provide products that meet and exceed market standards. In this sense, WLWORTH is an ISO-9001 udited and selection of raw materials from approved vendors. ontrol over our manufacturing process is vital.

9 QULITY ONTROL EQUIPMENT In order to assure that WLWORTH products comply with quality international standards, in-house equipments are kept for monitoring X-Ray Examination Equipment. WLWORTH has its own Ir-92 source up to 2 1/2 wall thickness to verify the soundness of the casting raw material. PMI Equipment Equipment gives WLWORTH the capability to perform quick chemical analysis on incoming raw materials and on pieces after assembly to certify that materials used were produced and assembled in accordance with WLWORTH and the Magnetic Particle Test.- In a random basis for standard products or when a WLWORTH has Magnetic Particle Test Equipment to perform on ferromagnetic materials. Penetrant Test Examination.- WLWORTH has the personnel and materials to perform PT examination by solvent removable or water washable techniques. Test Loop WLWORTH products performing the test at maximum design pressure and Pressure Gradient Test Loop.- This test exposes Plug valves to the extremes of both positive and negative pressure gradients to verify that the plug in a balanced plug design will prevent lock-up into the body. 9

10 Metrology Laboratory.- WLWORTH developed a calibration and / or traceability of measurements to international standards. In this way, WLWORTH gets measurement control of its products to comply with international standards. Fire Test Facilities Low Fugitive Emissions Test.- When a ustomer requires low fugitive measure less than 20 ppm either in both static or Mechanical conditions at ambient temperature or thermal cycle operations. Ultrasonic Testing Equipment.- Using ultrasonic techniques, we can detect be radiographed. In addition we utilize these techniques to measure the wall thickness of castings and forgings. Tensile Test Equipment.- To verify the mechanical properties of materials used for manufacturing, WLWORTH tests samples on a random basis even Hardness Test Equipments.- We utilize hardness testing equipment to verify 10
