DATA SHEET Pneumatically operated 2 way angle seat control valve ELEMENT • Excellent combination of good control characteristic and high flow rate • Long service life • Control units can be mounted directly without external tubing • Stainless steel housing with thread, clamp and weld end connection Product variants described in the data sheet may differ from the product presentation and description. Can be combined with Type 8696  Digital electropneumatic positioner for the integrated mounting on process control valves Type 8693  Digital electropneumatic process controller for the integrated mounting on process control valves Type 8692  Digital electropneumatic Positioner for the integrated mounting on process control valves Type 8694  Digital electropneumatic positioner for the integrated mounting on process control valves Type 8792  Digital electropneumatic Positioner SideControl Type description In line with Bürkert’s philosophy for modular valves and sensors the construction of Type 2300 angle-seat valve fulfils tough criteria for process environments. Unrivalled cycle life and sealing integrity is guaranteed by the proven self adjusting packing gland. The parabolic trim results in a flow characteristic approximately 35 % larger than conventional control valves. It is available in either stainless steel on stainless steel or with a durable PTFE seal for tight shut-off. The design enables the easy integration of automation modules whether they are digital electropneumatic positioner or process controller. The fully integrated system has a compact and smooth design, integrated pneumatic lines, IP65/67, NEMA Type 4X protection class and superior chemical resistance. This system has been engineered for reliable accurate control in applications where high flow rate is an advantage.
