What is a Dual Chamber Orifice Fitting ?

Dual Chamber Orifice Fittings are used where it is necessary or desirable to remove the orifice plate from the fitting without interrupting the flow of liquid or gas in the pipeline. They are commonly used for measurement of natural gas, custody transfer, transmission pipelines or any installation where the pipeline cannot be shut down.

Function

Orifice plate can be replaced under pressure, no need to interrupt operation, avoid downtime, save time and cost.
The indicator can clearly show the open or closed position of the slide valve, which is helpful for safe operation.
More product line size and ANSI class selection range can meet a variety of application requirements
Design with optimum seal to avoid damage or equipment failure.
No bypass or additional valves are required, can be installed vertically or horizontally.
