RETENTION PENSTOCK FL SERIES Before installation, inspect the penstock to ensure no damage has occurred during transport or storage. Ensure that the penstock sealing area is clean, and check that the flap swivels without any difficulty on the lugs of the body. ‐ If the penstock is to be installed on a flange, inspect the pipe and the installation flange, ensuring they are clean and the flange boreholes standard coincides with the penstock boreholes standard. ‐ If the penstock is to be wall‐mounted, inspect the wall to ensure it is clean and flat. ASPECTS TO BE CONSIDERED DURING ASSEMBLY When mounting the penstock, it is vitally important that the turning point of the flap (body lugs) are, whatever the type of attachment or ...

RETENTION PENSTOCK FL SERIES Since each of these penstocks is designed to comply with the operating conditions of each installation, there are several options to install the FL penstock. The most notable are the two most common options: one is bolted to an existing flange and the other is mounted on a wall and secured with anchors. Each of these options is described in detail below. To mount the penstock bolted to a flange (fig. 5), these steps should be followed: ‐ Position the penstock supported on the flange of the installation, checking that the boreholes coincide with the penstock body boreholes. ‐ After ensuring that the borehole coincides, remove the penstock from the flange. ‐ Clean the face of the flange where the penstock is to be mounted. ‐ Position a sealtight joint on the flange, in order to ensure there are no leakages to the outside where the flange and the penstock come together. The seal to be installed will be selected in line with the working conditions inside the line (temperature, pressure, type of fluid, etc). ‐ Check that the penstock, the inside of the body and, above all, the sealing area are clean. ...

RETENTION PENSTOCK FL SERIES In order to install the penstock mounted on a wall and secured using chemical or expansion anchors (fig. 6), these steps should be followed: ‐ Check that the wall is completely flat, otherwise the body may become deformed and produce irreparable damage when tightening the anchoring. ‐ Place the penstock on the wall, ensuring the passage of the penstock coincides with the wall ...

RETENTION PENSTOCK FL SERIES These are the most common attachment options, although, as mentioned on other occasions throughout this manual, the design of these FL penstocks is defined in accordance with the customer's requirements in each specific project. In consequence, if you require a different attachment option, contact CMO's technical sales department for a bespoke project in line with your needs. The penstock can be installed secured to a wall with anchors or bolted to a flange; in all cases the ...

RETENTION PENSTOCK FL SERIES Once the penstock has been installed, check that all bolts, nuts and anchorings have been correctly tightened. All CMO penstocks are tested at its facilities, although the penstock may have become damaged during transport or assembly. Once installed, it is very important to check that the penstock works correctly, making sure that the flap swivels on its turning point without any difficulty, that it sits perfectly on the seal when the penstock is closed, etc. If the penstock has electrical accessories or you are in an ATEX zone, earth connections must be made once the penstock is in place but before operating it. If you are in an ATEX zone, check the continuity between the different elements of the penstock (EN ...
RETENTION PENSTOCK FL SERIES MAINTENANCE CMO will not be liable if the penstocks suffer any damage due to improper handling or without proper authorisation. The penstocks must not be modified except under express authorisation from CMO. The following instructions should be followed in order to avoid personal injury or material damage when carrying out maintenance tasks: The staff responsible for the maintenance or operation of the equipment must be qualified and trained. Use suitable Personal Protective Equipment (PPE) (gloves, safety boots, goggles, etc.). Shut off all lines which affect the penstock and put up a warning sign to inform about the work ...

RETENTION PENSTOCK FL SERIES REPLACING THE SEALING JOINT Make sure there is absolutely no pressure or fluid in the facility. Place the flap (2) in completely open position. Secure the flap (2) in this position using more than one system. Unscrew and remove the screws (8) from the flange (4) and the seal (3). Remove the flange seal (4) and finally the deteriorated seal (3). Clean the seal housing (3). Fit a new sealing joint (3) with the same dimensions as the old one. Return the flange (4), checking that it is correctly fitted and the seal (3) has not been damaged in the process. Remove the systems to secure the flap (2) in open position, and carefully position it in closed position. Before starting up the installation, check that the flap (2) swivels freely on its turning point; also check that the flap (2) sits perfectly on the closing seal (3) when the penstock is closed. Note: The numbers in brackets refer to fig. 11. ...
RETENTION PENSTOCK FL SERIES LUBRICATION The only point of the penstock which requires lubrication is the turning point, which we recommend greasing about twice a year. After the maintenance and in an ATEX zone, you must check the electrical continuity between the pipe and the rest of the valve’s components, such as the body, flap, stem, etc. Standard EN 12266‐2, Annex B, points B.2.2.2. and B.2.3.1.). STORAGE To ensure the penstock is in optimum conditions of use after long periods of storage, we recommend º storing it in a well‐ventilated place at temperatures below 30 C. It is not advisable, but, if stored outside, the penstock must be covered to protect it from heat and ...
