1. Стр. 1 Technical information

   The Oventrop Quality Management System is certified to DIN-EN-ISO 9001 Regulating valve “Cocon” Measuring technique “eco” and “classic” Tender specification: Oventrop regulating valves “Cocon” with proportional presetting with memory position, with draining, filling and isolating facility with…

2. Стр. 2 Presetting

   1 Unscrew protection cap. 2 Close the valve disc by turning a 4 mm spanner clockwise. 3 Then preset the valve disc by turning the 4 mm spanner anticlockwise according to the number of turns selected from the flow chart (illustr. 1). 4 Finally, using a screwdriver, turn the lock nut clockwise until…
