|Process Valves

The applicable fluid of VNC, VNH, SGC, and SGH series valves is listed as coolant in the catalog, but can they be used with water or pure water?

VNC, VNH, SGC, and SGH series valves do not support the use of water or pure water. Water or pure water may cause the inside of the body to rust, resulting in failure.
Coolant contains anticorrosive agents and is used to prevent rust.
The coolant valves are therefore designed to be used with coolant only.
