The Barton Firtop Duplex Strainers represent a class of high-performance filtration systems engineered for continuous operation in critical industrial applications. Designed to eliminate downtime during maintenance, these strainers feature dual filtration chambers \u2014 one operating in service (duty) while the other remains on standby for cleaning or replacement. This configuration ensures uninterrupted process flow, making it ideal for industries where reliability and efficiency are essential. Among Barton Firtop\u2019s duplex range, the flagship Rotagate\u00ae Dual Basket Strainer stands out for its patented dual-gate valve mechanism, which allows seamless changeover between chambers using a single handwheel operation. This unique, synchronized system rotates around a central shaft to divert flow without process interruption. The design achieves 100% sealing integrity, maintaining full pressure containment from zero bar to 1.1 times the rated pressure.

The Rotagate\u00ae Dual Basket Strainer has duty and standby chambers with a pair of integral synchronised dual gate valves that rotate around a common central shaft to facilitate changeover, enabling continual operation whilst cleaning the \u2018off-line\u2019 strainer basket.<\/p>

This unit is of cast construction and comprises a central strainer body casting with a pair of inlet\/outlet header castings that house the Rotagate\u00ae valve mechanism. The unit has a single handwheel operation, facilitating diversion of the flow from \u2018duty\u2019 to \u2018standby\u2019 chamber without process interruption. The contaminated basket is accessed via the top bolted closure which can optionally be facilitated with quick-release swing bolts. The changeover shaft is fitted with an axial indicator to identify the on-line chamber. The simplicity and ease of operation is unique in this product class, whilst a 100% seal is achieved for the isolated chambers, from Zero Bar through to 1.1 x Full Flange Rating. The CFD optimised flow-path, coupled with angled top strainer baskets achieves the lowest pressure loss coefficient available for a dual strainer with this unique, time-proven, world-leading design.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
