English - Cepex 32614 Manual De Instrucciones

1. DEFINITION
Butterfly valve for isolating or regulating the flow in liquid handling systems. The liquid can flow in both directions.
Design based on the EN ISO 16136 Standard.
The valve is available with PVC-U discs and EPDM and FPM sealing gaskets. The choice of material for the disc and gasket depends
on the type of liquid to be carried and on the working temperature of the liquid, in accordance with the chemical resistance tables
available on our website and the pressure/temperature chart in this Manual (G4.1).
2. WARNINGS
• Carefully read these instructions before handling the valve and observe their recommendations. Any damage caused by failure
to observe these instructions is not covered by the warranty.
• All connection and handling tasks must be performed by qualified personnel.
• The maximum service life of the valve is specified in EN ISO 16136. It is verified on the production plant by aging tests specified
in the standard.
• Correct installation and handling of the valve, as well as adherence to the maximum pressure and temperature conditions
specified in this manual are essential for preserving the service life of the valve.
• The driven liquid must be compatible with the valve materials. Consult chemical resistance charts published by Cepex or con-
sult the technical department.
• Using tools for opening or closing the manual valve control is not recommended. This process must be done manually.
• Before carrying out any maintenance operations on the pipe or valve, ensure that the system is depressurised by releasing the
pressure and emptying the pipes, following the specific safety regulations of each product.
• Turning the handle when the safety lock is in place could damage the valve.
• Avoid shocks during transport, since they may damage the body and mechanism of the valve. Store the valve in the original
packaging, protected against humidity and direct sunlight.
• Before installation, check that the valve is undamaged and that it contains all the parts required for installation.
• After long periods of inactivity, check the grease on the gasket and follow the maintenance instructions set out in this manual.
The grease must be compatible with the valve materials.
• It is important to avoid rapid closure of valves to eliminate the possibility of water hammer causing damage to the pipeline.
• When using the valve as the final element of a installation, take into account the risks of the liquid and control the pressure and
temperature, according to the standards of safety of each product.
