FUNCTION
A built-in return spring in the two-way valve
produces an opening force.
In the three-way valve and the three-way valve
with bypass, the spring produces a closing force
on the A to AB ports.
The valves are supplied with a screwed-on
adjustment cap for manual operation and for
protection of the stem.
Soft seat provides low leakage rate and high
rangeability.
