Installation
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Use hoisting equipment for heavy objects (weighing approximately
20 kg or more). Failure to do so may result in back strain or other injury if
the object should fall.
CAUTION
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from
the discharge of fluids.
CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
Make sure that the piping where the product is to be installed is constructed properly.
If the piping is not correctly constructed, the valve may not perform optimally.
1. Before installation, be sure to remove all protective seals.
2. When installing the product, in order to facilitate installation and removal of the
actuator, leave a space of at least 150 mm above the top of the actuator, and a
space of at least 100 mm to allow for positioner cover removal.
3. Make sure that the temperature of the flow medium and the ambient temperature of
the installation location do not exceed the valve and actuator temperature limits.
4. Before installing the product, blow out the inlet piping to remove any piping scraps,
dirt, welding chips, etc.
5. This valve is a control valve. Though it adequately performs the function of a shutoff
valve at start-up, frequent use as a shutoff valve causes a drop in performance. Be
sure to install a manual or automated shutoff valve at inlet and outlets.
6. Do not install the valve in locations in the piping where foreign matter accumulates
or where impact from water hammer occurs.
7. Wherever possible, install the valve in horizontal piping, making sure that the
actuator is in a position as close to perpendicular to the piping as possible.
8. Be sure to install the valve so that the arrow showing on the body is pointing in the
direction of flow.
9. Be careful that the piping gaskets do not protrude beyond the inner diameter of the
flange. The type of medium being used and the temperature must be taken into
account in order to select a gasket of a suitable material.
10. Make sure that the valve is not bearing excessive weight from the piping and avoid
uneven tightening by making sure that all the bolts on the flange connection are
tightened evenly.
11. Before connecting the air lines for the air that is to be piped to the positioner/
actuator, blow out the air in the lines to remove any dirt, foreign matter, oil or water
from inside of the piping. Don
’t use air that contains water or oil. If air that contains
water or oil is used, install an air filter/regulator (non-lubricator) to prevent the flow of
water or oil into the positioner.
