WARNING!

Physical injuries and damage to property and the

environment caused by media escaping under high

pressure

With the pressurisation of the product, as a result of poor

sealing of the connections, media under high pressure can

escape.

Due to the high energy of the media that can escape in

the event of a failure, the possibility of physical injuries and

damage to property exists.

▶

The sealing of the connections must be carried out expertly

and checked for leak tightness.

WARNING!

Physical injuries and damage to property and the

environment caused by improper handling.

Incorrect opening or closing of a valve can lead to the

escape of media.

▶

The operator must be aware of the consequences prior to

changing the state to a specic valve position.

5.1 Mounting

■

When unpacking, check all components for any external damage.

If a return is needed, please follow the instructions given in chapter

8.2 “Return”.

■

5.2 Commissioning and operation

To close the valve, turn the handle in a clockwise direction as far as the

stop. To open the valve, turn the handle anticlockwise as far as the stop.

It will take approximately 4 turns from open to closed and vice versa.

The ow can be controlled by not totally opening/closing the valve.

Please note that the handle may present a slight play and

spin freely up to a quarter turn when in the depressurised

state. This is due to the constructive design.

■

The valve, especially the handle, must not be subjected to any exter-

nal loading (e.g. use as a climbing aid, support for objects).

■

The handle may only be used by hand; the use of tools is not

accepted.

■

The torque on reaching the valve stop must only be hand-tight.

■

Ensure that all valves of the product are closed prior to opening the

main valve of the process line.
