Features

Aluminum wetted 2K-UL valves are lightweight and inexpensive, but have less chemical
compatibility than stainless steel wetted valves.
The internal air trigger controls the air piston that operates the 2K-UL valve. A pilot port
can be used to control a pump motor.
The switch signals the customer's controller to open and close the ports on the 2K-UL
valve using a remote 4-way air control valve which is not included.
The wide ratio 2K-UL valve has two features: a center inject nozzle in the nosepiece and
a "shower head" tip. The features are helpful in applications when the mix ratio volume is
greater than 10:1, specifically when minor volume is a lower viscosity than major volume.
Frequent cleaning intervals are required to maintain the center inject nozzle and shower
head tip.
