Design features

– Fabricated construction
– Minimizing of heat loss of process temperature due to optimized thermal insulation of body, bonnet (uncooled) and paddle
– Thermal insulation comprising various materials
– Optimization of thermal insulation, allowing for water cooling of only the body seats and paddle
– Special design cooling water passages provide optimum flow
– Sealing in both directions, floating paddle design
– Valve actuation in accordance with customer’s requirements (man./electr./hydr./pneum.)
– Pressure rating up to PN 6
– Service temperatures up to 1650 °C (3000 °F)
– Nominal diameters up to 3000 mm (120 inch)​
– Other sizes or operating conditions on request
– German and foreign patents pending

This design guarantees:

– Considerable reduction of required quantity of cooling water (also during emergency
operation)
– Extended operational life of the valve due to increased thermal insulation, reducing thermal
stresses to the valve
– No deposits in cooling water channels
– Due to optimized design valve is easily maintained
– Reduced operating costs due to:
– decreased heat loss of process temperature
– reduction in amount of cooling water
