ADCA TWO-WAY GLOBE CONTROL VALVES V25/2 (EN) DESCRIPTION The ADCATrol V25/2 is a series of single seated, two-way globe valves designed for process engineering and industrial applications, where events such as erosion, cavitation or flashing may occur. These valves can be assembled with pneumatic, hydraulic or electric actuators, for modulating and shut-off control tasks. MAIN FEATURES Robust construction. Modular design to meet process requirements. Stainless steel trim. OPTIONS AND ACCESSORIES: Bonnet extension for high and low temperatures. Various stem sealing options including bellows sealing. Soft, stellited and high-performance metal valve sealing. V-port guided and perforated plugs. Low noise, anti-cavitation single and multi-stage trims. Reduced bore trims including microflow. Pressure balancing trims. Silencers. Saturated and superheated steam. Hot and superheated water. Air, gases and others. V25/2G – SG iron. V25/2S – carbon steel. V25/2i – stainless steel (only available from DN 15 to DN 100). VALVE SIZES: V25/2G – Flanged EN 1092-2 PN 16. V25/2S and V25/2i – Flanged EN 1092-1 PN 16 or PN 40. Standard PN 16 DN 65 flanges are supplied with 4 holes. 8 holes, according to EN 1092-1/-2, on request.
