| TS941 HIGH PRESSURE SPOOL VALVE |
The Spool Valve consists of two body segments, (an air cylinder
segment and an air cylinder cap) and a balanced spool shaft.
The Spool Valve is based on a balanced spool design to create
a fast "ON/OFF" fluid dispensing function that is
not affected by material input pressure. The hardened spool
slides in Teflon® seals and is suitable for use with materials
having a viscosity of 100 CPS to over 3,000,000 CPS at pressures
of up to 2,500 PSI. The spool action displaces a portion of
the material back into the nozzle during shut off. This creates
a "suck-back" anti drip feature. Part number 934-003-000
is an available option providing adjustable suck-back limitation.
An oil chamber is provided above the upper seal to create
an additional liquid seal that will prevent moisture from
being carried on the spool.
The valve design facilitates
easy maintenance without the need for special tools. The
valve is designed to be opened by air pressure and closed
by a return spring (single acting). A port is provided so
that the valve may be connected for air closing without
the spring (double acting). All side ports can be rotated
in 120 degree increments (TS941) or 90 degree increments
(TS941A) to conveniently locate valve connections.
