Specifications
Pneumatic System
with Low Impact and
Rapid Approach Control
Description
Pneumatic valve block for use with pneumatic weld
gun cylinders. The block has an integrated low impact
system and is provided with two solenoid operated
“Namur” or ISO size valves. One valve for the retract
(pre-stroke) and one for the weld stroke. The valves
can be of the single solenoid type or the double
solenoid type. The block is available for different
constructions of cylinders:
DH / WH = 3 Ported Cylinders
DP / WP = and 4 Ported Cylinders
Ordering Code:
See pages 7 – 13.
Dimensions:
See pages 15 – 18.
Applications
The Spotwelding System can be used with any
Pneumatic Spot Weld Cylinder.
Mounting
The weld block can either be mounted on the side of
the robot or directly to the cylinder. See pages 10 – 1
for bolt hole patterns for robot mount. Consult Parker
for cylinder mount application.
