Parker Weld-in
Valve Stations
Product Bulletin 10-02
Type: S8VS, S8ST
Purpose:
The S8VS and S8ST provide safe
and economical solutions for small
capacity lines. These products
feature a weld-in construction
which offers increased safety
over traditional two-bolt flange
connections. They come standard
with an integrated strainer which
eliminates the need to order and
install additional components.
The S8VS valve station is based on
the proven S8F solenoid valves, RSF
strainers, and R/S hand valves. The
S8ST solenoid-strainer combination
valve is also based on S8F and RSF.
Both share common components
which reduces complexity and spare
part requirements.
