Tomoe Extends Double Isolation Valve Range and Delivers Twice the Savings
Newport, UK - 12 August 2008 - Tomoe, a world leader in the development of butterfly valves and associated actuation and control systems, has extended its range of double isolation and bleed facility valves in response to the process industries increased demand for an improved shut off solution for critical applications. Available in a range of sizes from 2" to 54", Tomoe's double isolation valves are extremely efficient in any application where positive verifiable and maintainable shut off is required. The valves can be used in a variety of industries including chemical plants, refineries and the sugar and water industries.
"Due to legislation and safety initiatives in the process industry the use of double isolation for maintenance, and replacing gate valves for a double isolating butterfly valve, is increasingly popular with our customers" said Willie Duncan, managing director, Tomoe Valve Limited. "Our double isolation valves save time and money and provide a lightweight, cost-effective, easily maintainable solution for a variety of applications."
Tomoe's extended range of double isolation and bleed facility valves provide the security of guaranteed isolation while delivering the benefit of the triple offset, metal seated butterfly valve. By using the narrow face to face of a butterfly valve, double-sealing systems can be supplied within a ball, plug or gate valve, face to face with a bleed facility between the two positive seals, offering the customer improved flexibility.
The double isolation valve works by incorporating two valves into one integral cast body, eliminating the need for extra joints, gaskets and bolting, thus reducing the potential for leak paths. The integration of the two valves reduces the material mass resulting in a lower initial cost, reduced weight and ease of maintenance; both seal and seat are replaceable onsite without the use of specialist tools.
All standard materials conform to NACE, the product is fire tested to BS6755 part 2/ API 6FA/AP1 607 and is also available fully rated to class 2500lb.
