Flowserve has improved the design of the Valtek FlowTop control valve to meet the global requirements for general service and moderately severe service applications.
The new FlowTop General Service valve builds on the proven FlowTop GS and Valtek GS control valves to meet a broad range of requirements by providing: one standardized, versatile control valve, precision control; a variety of trim and packing options; simplified maintenance; and cost savings through parts interchangeability.
The valve includes a fully integrated package features an updated streamlined design for maximum performance and operating efficiency in all general service applications. Its updated design is easy to select, size, configure and order.
A standardized design with interchangeable components simplifies maintenance and minimizes costs related to inventory and spare parts. In addition, the valve offers packing options to meet stringent fugitive emissions requirements (ISO 15848-1 Class B CC1). Also available are multiple seat designs (threaded or clamped), packing options (external or internal live loaded) and single-stage trim solutions for mild cavitation and noise reduction.
