MOUNTED
COIL ORIENTATION
The solenoid pilot can be mounted in two possible positions by rotating the
solenoid base through 90° (FIG 1). This is achieved by releasing the two M4
pozi-drive screws which secure the solenoid pilot to the valve body. When
changing the solenoid pilot position care should be taken to ensure the
triangular gasket seal is in place. (FIG 2)
DO NOT SCALE - IF IN DOUBT ASK
REMOVE ALL BURRS

The coil itself can be rotated in 90° steps by releasing the four securing
screws. (FIG 3) When rotating the coil care should be taken to ensure the
core assembly (core, spring, seal and washer) remains intact and alined
correctly. This is easily achieved by only lifting the coil the small amount
required to clear the screws enabling the coil to be rotated.
