CRANE Cast Steel Globe Valves
Crane Globe valves are ideal for throttling service. Their flow characteristics permit accurate and repeatable flow control. However, caution must be exercised to avoid extremely close throttling when pressure drop exceeds 20%. This creates excessive noise, vibration and possible damage to valves and piping. Crane does not recommend applications in excess of this due to possible damage to the valve.
