Tomoe: Double Isolation & Bleed Valves

The need for Positive, Verifiable, Maintainable & Repeatable Isolation in critical applications has led to the wide-spread use of Double Isolation & Bleed valves in the process industry.

Traditionally these have been ball or plug valves, both of which penalise the user in terms of weight, operating torque, initial material cost and of course maintainability, which translates into a higher cost of ownership.

Safety initiatives and legislation in the process industry created the requirement for double isolation during planned and emergency shutdowns.

Tomoe developed a range od Double Isolation & Bleed Butterfly Valves which provide the security of guaranteed isolation whilst delivering the benefit of the triple offset, metal seated butterfly valve.

Replacing the traditional DBB valves with a Double Isolating Butterfly Valve saves time and money. 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.
