EJ ABO valve OONDOFPWDNDH Operating Instructions For ABO Butterfly Valves Series 900 Introduction Safety Instructions Valve Identification Transportation and Storage Installation into Piping Pipe Pressure Test Operation and Maintenance Assistance in Case of Failure Valves with Electric or Pneumatic Actuator EJ ABO valve 4qpowente 1 Introduction Centric rubber seated valves ABO Series 900 have been designed to close or regulate the flow of fluids in pipelines The correct type and material design is determined using brochures or manufacturer s recommendations during consultations 2 Safety Instructions Installation operation and maintenance may only be performed by properly trained and instructed staff For detailed safety regulations see the separate document which must be read carefully before installation 3 Valve Identification Series 600 is designed for normal use for water hot water air etc The material of the disc is optional cast iron brass stainless steel The material of the seat EPDM or NBR is indicated on the label Series 900 is designed for chemical gas industry etc applications These valves have a label specifying the material maximum temperature and pressure 4 Transportation and Storage Valves must be stored indoors in dry and dust free environment at normal temperatures Valves must be stored in a slightly open position never fully closed Va2. Valve leaking when Worn disc erosion Replace the disc closed Incorrect closed position Check and adjust the position 9 Valves with electric or pneumatic actuator The above principles fully apply to these valves It is also necessary to observe and check the correct end position adjustment of the actuators The positions of the actuators have been pre set by the manufacturer and may not be adjusted The intake or exhaust of controlling air in pneumatic actuators can be adjusted to avoid their quick closure and hydraulic shock in the pipes Remove and clean the valve or replace the damaged parts Check the pressure of the medium
3. lves must not be stacked on each other this could cause damage to the collar When transporting large valves using a crane they should only be handled by attaching the rope to the body not the actuator or the lever 5 Installation into Piping The procedure is graphically described in the document Installation Instructions Valve sealing surfaces are made of rubber gasket parts it is therefore necessary to use flanges with flat sealing strips e g B shape according to EN 1092 Before installation it is necessary to examine e Whether the PN DN and materials of the supplied valve corresponds to the intended use e Whether no damage occurred during transportation Do not use damaged valves e Check the correct functioning of the valve full opening and closing e Counter flanges must be aligned and parallel any impurities and solid particles from the flanges and piping must be removed The direction of the flow and valve position are optiona Horizontal position of the valve stem is recommended for DN 2 350 Flanges should be tightened so that a contact metal to metal between the flange and valve body is ensured This is the only way to guarantee tightness no other sealing is used 6 Pipe Pressure Test The actual valve is pressurized by the manufacturer When fitted in the pipeline the entire pipe section with valves needs to be pressurized The following must be observed e Newly installed section must be carefully rinsed cleaned t
4. o remove all mechanical impurities e Valves in open position pressure at 1 5 times the PN e Valves in closed position pressure at 1 1 times the PN 7 Operation and Maintenance Valves can be manually controlled using normal force it is not recommended to extend the length of the lever When the lever is parallel to the pipe the valve is opened the position of the lever perpendicular to the pipe means that the valve is closed Opening and closing using the lever must be gradual rather than abrupt to avoid hydraulic shock The valves are maintenance free it is only necessary to check during operation if the outer surface does not leak If the valve remains in the same position for a long time it is recommended to close and open the valve repeatedly at least 4 times per year 4qpowente EJ AB O valve 8 Assistance in Case of Failure In case of failure and repair it is necessary to adhere to all safety rules see the separate document Safety Instructions Failure Cause of failure Failure elimination Insufficiently tightened Ys Tighten the bolts flange bolts Reinstall the valve in the correct Valve not centred ws position Internal diameter of the flange too large Leakage between the valve and flanges Replace flanges Burnt or damaged Replace the seat seat Solid particles between the seat and the butterfly Valve does not close Hardened or porous seat Replace the seat Pressure of the medium too high
