Operations and Maintenance Instruction
1 Transport
Upon receipt, please check the valve with eventual equipment (Actuator, etc.) for any
damage which may have occurred during shipment.
When shipping the valve, it should be made sure that it is secured on a pallet
avoiding it to slide or fall over during transport. If transporting or lifting the valve with
a rope or hook, it should be attached in a way avoiding that the valve accidentally
slips sidewards.
Do not use any lifting tackle (rope, chain, sling..) through the open valve.
2 Safety indication
If operating temperatures are > 50 ° C, protection against accidental contact and
spray -risk has to be applied.
Connecting the electrical- or electro pneumatic- connections has to be carried out by
authorized professional staff only.
When operating (on - off cycling) the valve while not flanged in line, do never attempt
to touch the inside of the ball (bore).
In case of toxic, corrosive and explosive fluids, respective guidelines need to be
followed. When disassembling the valve, make sure that possible contaminated
residues are disposed off as hazardous waste.
3 Installation
Pipeline
Install the valve into the line so that the arrow on the valve body points into the flow
direction. Should the actuator be too heavy, separate bear up support may be
required.
Install the valve without strain and tension. Additional forces by the pipeline are not
allowed (see DIN 2502).
The ball valve should be flanged in by using standard gaskets.
Make sure that the gaskets are not damaging the ceramic inlet and outlet
liners of the valve.
