VEX1*3*, Power Valve, Precision Regulator
Power valve series VEX includes a regulator valve (VEX1*0), precision regulator (VEX1*3), 3 position valve (VEX3) and a economy valve (VEX5). The 3 port large capacity poppet exhausting regulator is equipped with a relief port the same size as the connection port. The 3-port, 3-position double solenoid that permits vacuum suction, vacuum destruction, & suspension (closed) is ideal for a system where many valves are used.

Note 1) Not conforming to ISO1179-1.
Note 2) The optional parts are shipped in the same package.
Note 3) If a pressure gauge other than that which is indicated in the option table is to be used, also enter the part number of the pressure gauge.
Refer to the pressure gauge guide in Best Pneumatics No. 7 for details.
Example: VEX1333-03
G36-4-01
Caution
Using the External Pilot
1. If a pressure difference over 0.1 MPa between
the supply and the set pressure cannot be
maintained, change to an external pilot to
obtain the necessary pressure difference.
2. If a mist separator cannot be installed on the
supply side, change to an external pilot, and
make sure to install a mist separator on the
pilot side.

Note) O-rings cannot be shipped as a single unit.
How to Switch to External Pilot
1. Using a flat head screwdriver, remove the
fixed orifice from port P1.
2. Install the fixed orifice facing in the opposite
direction (external pilot). Install it carefully
to prevent damage to the O-ring.
3. Tighten the fixed orifice again and connect
the pilot piping to port P1 using an M5
fitting.
