Pressure Measurement & Control


Replacing a process pressure transmitter without emptying the vessel

February 2001 Pressure Measurement & Control

Up to now, replacing a process pressure transmitter mounted on a vessel required an emptying of the vessel. With Vega's ball valve fitting, this extra work has become unnecessary.

The fitting is provided with a mounting flange on one side, which is screwed to the vessel, and with a socket on the other side for holding a process pressure transmitter type D84 with process connection FG4. If the ball valve fitting is closed, the transmitter can be safely and easily installed or removed. The pressure acting on the ball valve can be up to 2 bar (200 kPa, ie the pressure of a water column approx. 20 m high).

The ball valve fitting is available with the following flange sizes: DN 50, DN 80, DN 100, ANSI 2", ANSI 3" and ANSI 4".
