Air operated 2, 3 port valve (coolant control)
Overview
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.
Features
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.
