Dorot Series 95/96

The uPVC valves, models 95 (threaded) and 96
(solvent welded) are designed to be used in
high-flow irrigation plots and flood tables. The
direct installation on-to the PVC pipelines and
the optional underground installation, assist in
reducing both the installation costs as well as
discarding surplus friction-losses by eliminating the
use of elbow joints in above-ground installations.
Unique diaphragm design generates surge-free
closure even at high velocities.
Unique hydrodynamic design allows exceptionally
low pressure losses at high flow rates, stable
regulation from maximal to near zero flows,
surge-free closure and simple, minimal maintenance.

Features:
• Structural simplicity
• Superb hydraulic performance
• Offer high resistance to corrosive fluids and can be used
for aggressive media conduction
• Light-weight, cost-saving
• Minimum maintenance - maximum dependability
• Simple to install with slip or threaded PVC connections
• May be installed to an underground, soil-coverd pipeline

3. Apply one layer of cement on the end of the pipe on both sides of the valve, as close as possible to
as well as in the valve interior. the valve body.
4. Insert the pipe into the valve until the
marked point is visible and turn the pipe a
quarter of a circle. Keep the parts stationary
and then place the unit carefully on the
ground. This allows the cement to harden.
* Remember that in low temperatures, glue
hardens at a slower rate, so when the temperature
is low be more cautious and allow more time for
the cement to harden.
5. If the valve is installed in an open field make sure Metal Support
the valve bonnet is facing up in order to provide
better protection.
6. Please use a cement that is recommended by the
PVC pipe manufacturer.
Caution - When the temperature is lower than 10
degrees Celsius the uPVC body is more vulnerable to
blows and may crack. Cementing in these conditions
should be avoided.
