Function, section, symbol

The pressure gauge isolator valve type AF 6 is a 3-way longi-tudinal valve for manual actuation. It is used for checking the occurring operating pressures.The valve basically comprises of housing (1), spool (2), com-pression spring (3), rotary knob (4) and pressure gauge con-nection piece (5). It has two spool positions as well as spring return to the initial position.In the initial position, the connection from port P to the pres-sure gauge is blocked by the spool (2) and the pressure gauge is connected with port T. By actuating the rotary

knob (4), the spool (2) is pushed into the operated position and opens the connection from P to the pressure gauge. The connection to T is blocked. By rotating the rotary knob (4) by 45°, the spool (2) can be engaged.After releasing the locking mechanism, the spool (2) is moved back into the initial position by the compression spring (3) and unloads the pressure gauge.The valve can be used for subplate mounting or for in-line mounting. The pressure gauge can be screwed into the valve housing or installed separately (see installation examples page 3).

1) The cleanliness classes specified for the components must be adhered to in hydraulic systems. Efficient filtration prevents malfunctions and at the same time prolongs the service life of components.

For the selection of the filters, see data sheets RE 50070, RE 50076, RE 50081, RE 50086, RE 50087 and RE 50088.
