ROUTH® expanding plug valves are designed for applications where positive shut-off, verifiable zero leakage and double bl ock and bleed (DBB) capabilities are required. They meet API-6D definition of Double Isolation and Bleed valves (DIB) as d efined in paragraph 4.8. They are ideal for a variety of applications including leased automated custody transfer (LACT), product metering, aviation fueling, product isolation, blending, lockout/tagout (LOTO), multi-product manifolds, tank storage and other DBB applications. The ROUTH® is a single valve solution that simultaneously blocks both the upstream and downstream flow while allowing the u ser to verify seal integrity using a manual or automatic body bleed system. It replaces older double block and bleed systems t hat use two valves with a spool and bleed valve in-between. It also has significant design advantages when compared with some other single DBB valve designs. All ROUTH® DBB expanding plug valves are manufactured and monogrammed per API 6D and ISO 9001, fire tested per API 6 07 and API 6FA and have specific certifications such as CE/PED, CRN (Canadian Registration), TA-Luft or similar design or r egional certifications where appropriate. ROUTH® DBB expanding plug valves have been determined to be a “Product of the USA “ by the US Customs and Border Protection Agency (CBP). This applies to valve procurement for both commercial and US military installations.
