Danfoss HP230N Externally operated 2/2-way straight-seat valves

Danfoss HP230N is a compact externally operated straight seat valve for use in robust industrial applications.
The externally operated valve can operate at very high medium temperatures and viscosities, and is insensitive to dirt particles in the medium; thus, it is often called a "trouble-shooter" valve.
