1022/2-way Angle-Seat Valvefor media up to +180 °C (356 °F)2000Type 2000 can be combined with...• High flow rates• Very high cycle life• Threaded and weld end body accordingto ISO, DIN and ASME• Deliverable with flow direction below orabove seat• Simple conversion of the control functionProcess ValvesType 6012/6014 PPilot valveType 8631TopControl On/OffThe externally piloted angle-seat valve is operated witha single or double-acting piston actuator. The actuatoris available in two different materials, depending on theambient temperature. High flow rates are attained withthe gunmetal or stainless steel 2-way body.The reliable self-adjusting packing gland provides highsealing integrity. These maintenance-free and robustvalves can be retrofitted with a comprehensive range ofaccessories for position indication, stroke limitation ormanual override.The reliable self-adjusting packing gland provides highsealing integrity.
