Two-way control valves with one-seat design A. Hock Series 2000 valves are our two-way control valve all-rounders. Available in both standard and more complex versions, the valves of this series are suitable for almost all process-related applications. The straight-through valves are single-seated and actuated by electric or pneumatic diaphragm actuators. The big advantage: Thanks to efficient warehousing, specific control valves are available for dispatch within 24 hours, in quantities of one or more. Tight finish in seat and plug • Function: Due to high accuracy of the individual parts, a leakage rate of 0.01 % of kvs is achieved without rework • Benefit: Cost reduction, as no rework is required when replacing the trim. Plug and rod welded together • Function: Very good alignment of taper, seat ring and guide bush • Benefit: Cost reduction when replacing the trim Three different characteristic curves available • Function: By replacing the plug: equal percentage, linear, open-close • Benefit: Easy adaptation to the behavior of the control loop Interchangeable trim-parts • Function: Characteristics, kvs values, materials, pressure compensation and sound reduction can be changed by changing the plug and/or seat ring. • Benefit: High flexibility is achievable with low inventory costs
