Tyco Launches Series 300

Ultra-Seal Series 300

Tyco, the global leader in flow control, introduces the Series 300 range of Ultra-Seal ball valves. Designed and manufactured by Hindle Cockburns in Leeds, United Kingdom, the Series 300 range is the result of extensive research and development that delivers significant benefits to users who are looking for top-end performance in demanding environments. With a full range of seating options including soft, carbon graphite and metal, the Ultra-Seal Series 300 range is type approval tested by Shell GSI. The range is ideally suited for use in a wide variety of industries including petrochemical, chemical, oil and gas, LNG and marine.

The Ultra-Seal Series 300 is a range of two piece full bore, flanged, free-floating (seat supported) ball valves, incorporating mounting dimensions to BS EN 15081 and designed in accordance with ASME B16.34, BS EN ISO 17292 and ISO 14313/API 6D. The incorporation of soft, carbon graphite and metal seats are the most significant of a range of enhancements to the well-known and respected Series 200 range. These three seating options allow engineers to select the most appropriate seat design, for temperatures as low as -196C or as high as 450C. Soft seat designs are fire tested to BS EN ISO 10497 standard.

Where abrasive and corrosive fluids are a major concern, a range of ball and seat coating materials are available. Coatings include tungsten carbide, which offers corrosion resistance especially for aqueous solutions, nickel alloy coating, suitable where abrasion and particle erosion may be a challenge, or chromium carbide coating, also suitable against sliding wear, up to 450C.

The metal and carbon graphite seat designs incorporate spring materials for optimum seal performance and high integrity shaft seals give low emission performance, even under thermal cycling. Both the metal and carbon graphite seats have been tested to Shell MESC SPE 77/312 class A and meet leakage performance of BS EN ISO 15848-2 class A.

For maximum chemical compatibility with minimum coefficient of friction, the PTFE soft-seated design is recommended. The soft-seated design incorporates a floating ball design that provides tight shut-off in both directions to BS ISO 5208 rate A. Fugitive emissions are tested in all designs and approved to Shell MESC SPE 77/312 class A.

The design and low-temperature performance of the Ultra-Seal Series 300 has been validated in strict cryogenic testing conditions. Demand for valves that can safely and reliably operate in low or cryogenic environments has increased significantly in recent years. Tyco is poised to meet the challenge of tough operating environments with quality design and engineering, driving research and development into issues specific to extremely low temperature operation. This has led to breakthroughs such as the design of a modular extension bonnet to relocate stem seals to the ambient temperature zone, improved valve seat design and performance, cavity pressure relief and stringent leakage acceptance testing criteria.
