Page 6: Fitting And Commissioning
Other modes of fitting (e.g. pipe vertical, actuation shaft horizontal) are possible when this is specified in the order. The type BBF fully welded ball valves in sizes up to DN 100 (4“) can be fitted in all fitting positions without approval having to be obtained therefor from Böhmer GmbH. -
Page 7: Welding
3.2 Welding Depending on what is ordered, each ball valve has either two flange ends, one flange end and one welding-on end, or two welding-on ends. The welding-on ends and the flange connection sides of the ball valve are protected with an anti-corrosion agent when supplied. - Page 8 IMPORTANT The test pressure may not be more than 1.5 times the nominal pressure or, as the case may be, 1.5 times the permitted operating pressure. Carry out the water pressure test. After the water pressure test, move the ball to the fully open position again (or where necessary to the fully closed position) and drain the line.

Page 9: Operating And Test For Tightness
4. OPERATING AND TEST FOR TIGHTNESS 4.1 Opening and shutting off The open or closed position of the ball valve is defined by turning the actuation shaft by 90 ° to its limit position, i.e. so that the delivery flow has the full cross-sectional area open to it or so that the flow is completely shut off. - Page 10 The general safety regulations applying at the place of installation are to be observed in respect of the medium escaping into the atmosphere. DANGER There can be a DANGER TO LIFE depending on the medium! Wait until the complete system has been depressurized and that no more medium is escaping.

5.1.2 Ball valves with test connection: When there is a leak with this form of execution, the inside of the housing of the ball valve can be depressurized when the valve is in its closed position without the connected line of pipes having to be depressurized. The inside of the housing can also be depressurized when the ball valve is in its open position when this has been agreed in the order. -
Page 13: Variants
5.2 Variants There are three different forms of execution of the spindle passage. Variant 1 Medium is prevented from escaping through the spindle passage by two sealing elements (see Fig. 2, Fig. 3). Action Action Spindle handle (1) Locking screw (1.1) Spindle handle (1) Locking screw (1.1) - Page 14 Variant 2 Medium is prevented from escaping through the spindle passage by four seals (three O-rings and one flat seal). These seals can be replaced (see Fig. 4). Actuation handle (1) Locking srew (1.1) Stop disk (2) Flange plate (4) Screws (3) Seals (7) Flat seal (5)

6. ACCESSORIES 6.1 Injecting of sealing agent into the journal seal / seating rings The transportable and easy-to-use sealing agent gun generates pressures of up to 100 Mpa. The sealing agent used is a highly viscous paste. When it is necessary to inject sealing agent, a sealing agent cartridge is inserted in the gun, the cap is removed from the injection nipple and the connection piece of the gun is pushed over the injection nipple (see Fig.
