2 Specifications
2.1 Valve specifications
Note :
Impact resistance:
No malfunction occurred when it was tested with a drop
tester in the axial direction and at right angles to the main valve & armature;
in both energized & de-energised states and for every time in each condition
(Values at the initial period.)
Vibration resistance:
No malfunction occurred in a one-sweep test between
45 and 2000 Hz. Tests ere performed at both energized and de-energized
states in the axial direction and at right angles to the main valve & armature.
(Valves at the initial period.)
2.2 Solenoid Specifications
2 Specifications (continued)
Note) In common between 110 VAC and 115 VAC, and between 220 VAC and 230 VAC.
For 115 VAC and 230 VAC, the allowable voltage is -15% to +5% of rated
voltage.
2.3 Circuit symbol
Note)
The Reverse pressurization type valve can be used as a N.C. valve or as a Selector
valve. See below for piping method:
•
N.C. valve use
1 port : output port
2 port : waste fluid port
3 port : supply port
•
Selector valve use 1 port : output port
2 port : low pressure supply port
3 port : high pressure supply port
3 Installation
3.1 Environment
WARNING
1. Do not use in an environment where the product is directly exposed to
corrosive gases, chemicals, salt water, water or steam.
2. Products with IP65 and IP67 enclosures (based on IEC60529) are
protected against dust and water, however, these products cannot be used
in water.
3. Incorrect mounting of the product violates the IP65 rating. Be sure to read
the Precautions for each product.
4. Do not use in explosive atmospheres.
5. The product should not be exposed to prolonged sunlight. Use a protective
cover.
6. Do not mount the product in a location where it is subject to strong
vibrations and/or shock. Check the product specifications.
7. Remove emissive heat.
8. If using in an atmosphere where there is possible contact with water
drop-lets, oil, weld spatter, etc., take suitable preventative measures.
9. When the product is mounted in a control panel, or when it's energized for
a long time, make sure that the ambient temperature is within the specified
range.
3.2 Piping
1. Preparation before piping
Before piping is connected, it should be thoroughly blown out with air
(flushing) or washed to remove chips, cutting oil and other debris from
inside the pipe.
Install piping so that it does not apply pulling, pressing, bending or other
forces the valve body.
2. Sealant tape
When installing piping or fitting into a port, ensure that sealant material
does not enter the port internally. Furthermore, when sealant tape is
used, leave 1.5 to 2 thread ridges exposed at the end of the threads.
<For AC>
3 Installation (continued)
3. Avoid connection of ground lines to piping, as this may cause electric
corrosion of the system.
4. Always tighten threads with the proper tightening torques.
When screwing fittings into valves, tighten with the proper tightening
torque shown below.
Tightening Torque for Piping
5. Connection of piping to products.
When connecting piping to a product, avoid mistakes regarding the
supply port, etc.
3.3 Light/Surge Voltage Suppressor
<For DC>
In extreme conditions, there is a possibility of
serious injury or loss of life.
WARNING
If instructions are not followed there is a
possibility of serious injury or loss of life.
CAUTION
If instructions are not followed there is a
possibility of injury or equipment damage.
