12.1
Installation
(ref. to fig.: Pressure regulating valve)
 Grease fixing screws (hex. socket head screw M12 x 120, 10.9, order no.: 02.00825.0152) with Molykote 1000
(order no.: 04.02750.0011)
 Carefully place the valve in the correct position and press against the pump head. Ensure that the ring (50)
doesn’t fall apart and is in correct position.
 Set the fixing screws in place and tighten. Tighten the hex socket cap head screws (in a few steps) crosswise
(Torque 90 Nm) ensuring that the valve is absolutely parallel with the pump head. Tighten to 90 Nm.
 Lightly grease the connection armature (order no.: 00.00131.0121) with Molykote 1000 and tighten into the
valve.
 Screw membrane cylinder (for example no.: 00.06428.0025) or adjusting sleeve (for example: 00.01754.0028)
onto the pressure regulating valve by hand.
Tighten membrane cylinder only by hand! Under no circumstances with a tool.
 Connect the pneumatically control line onto the membrane cylinder
 If necessary remove plug (120) and screw pressure gauge (i.e. order no.: 04.02860.0009) with seal ring into
the housing (req. torque = 100 Nm).
12.2 Adjustment
 The pressure regulating valve allows a smooth increase of pressure from suction pressure to max. operating
pressure That makes an optimal use of the energy source.

Adjust the operating pressure via the control air pressure. The operating pressure is directly proportional to the
control air pressure with which the pressure regulating valve is admitted.
 Increasing the air pressure increases the operating pressure.
 Decreasing the air pressure decreases the operating pressure.
