Type R
All-Rubber Pinch Valve
Ǡ Automatic valve uses plant air
Ǡ Lightweight, all-elastomer design
Ǡ High cycle life
Ǡ Full port, large sealing area
Ǡ Cost-effective, maintenance-free design

Red Valve’s all Type R All-Elastomer Pinch Valve is an
ideal valve for water, chemicals, solids, and slurry applications. The valve is easily installed between two pieces of
pipe with hose clamps. Simply add 20 psi air pressure over
line pressure and the valve closes drop-tight. For example:
If process line pressure is 45 psi, 65 psi closes the valve.
It's that simple!
The Type R has all the advantages of a Pinch Valve: no
packing gland or seat crevices and a full port that eliminates bridging or slurry dewatering. Each time the valve
flexes, it self-cleans. The Type R Pinch Valve is ideal for
use with pulse type control systems. The lightweight
design of the Type R Pinch Valve makes pipe supports
unnecessary. The Type R is an excellent valve to have in
stock for an instant valve repair or to isolate a pipeline.
The valve body is elastomer reinforced with fabric, bonded
to the inner sleeve—the only wetted part. Air connection
is a 5/16" valve stem. The unique one-piece design of the
Type R Pinch Valve eliminates the need for actuators,
making this the most affordable, maintenance-free
automatic valve available to industry!
