Coolant valve
Air operated 2, 3 port valve
This is a reliable 2, 3 port coolant
valve with cylinder drive method.
This valve for tool machine cutting oil
or coolant control incorporates a
metal seal to prevent the entry of
cutting chips, abrasive grains and
foreign debris, and ensures highly
reliable control.
The air operated type and solenoid
valve mounted type are available.
These can be used in precise
machines.
Overview
High corrosion resistant
materials
Cast iron body, and stainless steel
metal seal used in valve seat. NBR
or FKM packing seal can be
selected. Materials optimum for
coolant are used.
Certain operation
Certain operation is enabled with
external pilot air operated cylinder.
Water hammer prevented
(Only 2 port valve)
Resistant to foreign matter
A metal seal is used.
Usable in flammable
environment.

(2) Pre-lubrication - This series is pre-lubricated, so no lubricator
is required. However, once lubrication has been started, it
must be continued so that the lubricant is not used up. For
lubrication, use the turbine oil Class 1 ISO VG32 (#90) or
equivalent.
(3) Filter - Install a filter with a 5 μm or less filter element.

1. Safety designing
CAUTION
䡵Leakage current from other fluid control components
When operating the solenoid valve with a programmable
controller, etc., check that the output leakage current from the
programmable controller is within the following specifications.
Failure to observe this could lead to malfunctions.
䡵
CVSE Series cannot be used in an explosive gas atmosphere.
When using in an explosive gas atmosphere, change to the
CVE Series, and provide a separate explosion proof solenoid
valve on the pilot air circuit.
䡵If there are high levels of dust in the area, install a downward-
facing silencer or elbow joint on the exhaust port so that dust
does not enter.
䡵
When using in a place where water splashes on the valve, take
appropriate measures to protect it.
WARNING
2. Working fluid
WARNING
3. Working environment
4. How to use
䡵Working fluid
The compatibility has not been evaluated with all coolants.
Particularly, if coolant contains high levels of chlorine or
sulfur, materials used at wetted parts could be adversely
affected. Confirm the compatibility when making a selection.
Non-corrosive fluids refer to fluids that do not affect or are not
affected when they contact the valve's wetted part materials.
cast iron (nickel plating), stainless
steel, nitrile rubber or fluoro rubber,
and epoxy resin adhesive.
䡵External pilot air
(1) Drainage measures - Compressed air contains high levels
of drainage (water, oxidized oil, tar, foreign matter) that
can significantly reduce the reliability of pneumatic
components. As measures against drain, improve air
quality by dehumidifying with an after cooler or dryer,
removing foreign matter with a filter, and removing tar with
a tar removal filter, etc.
CAUTION
䡵Pilot air pressure
Use pilot air pressure in accordance with the specifications.

CAUTION
1. Piping
䡵Do not pipe using the solenoid valve section. There is a risk
of damage. (For solenoid valve mounted type)
Installation & Adjustment
䡵When piping the CVE or CVSE Series, pay attention to the
supply ports on the unit and pilot operation sides.
Wetted part materials:
100 VAC : 3 mA or less
200 VAC : 1.5 mA or less

2. Assembling & disassembling
䡵Wiring of solenoid valve mounted type
(1) Refer to connections in pages 54 to 55 in the Introduction
when wiring to a DIN terminal box or T type terminal box.
(2) The size of the screw for the junction box outlets of the
DIN terminal box can be changed from Pg9 to G1/2
using the optional connector below.
䡵A spring is used in the cylinder cover. When
disassembling this type, the spring could pop
out and cause injuries, so take care.
The NC (normally closed) type 2 port valve has
a snap ring to prevent the spring from popping
out. Do not remove the snap ring.
(3) Coil direction can be changed 180˚. To reverse the
electrical connection direction, rotate only the coil. Do
not lose internal parts when removing the coil.
CAUTION
1. Maintenance & inspection
During Use & Maintenance
䡵Pilot air pressure
Use pilot air pressure in accordance with the specifications.
䡵If water hammer occurs when a 3 port coolant
valve for medium/high pressure operates,
reduce the noise as follows.
(1) Install a metering valve on the valve IN side, then adjust
the metering valve to reach the required flow.
If these countermeasures fail, contact CKD.
