WHAT ARE Duplex Round Bar?

A fluid measurement system employs a variety of Washers, including the Duplex Round Bar, which serve as the primary safeguard for safety and quality within the system. These Washers are utilized for a range of functions, including measuring, isolating, blocking, and bleeding static pressure, venting, pressure gauge differential pressure, and more. We are a leading Duplex Round Bar Manufacturer and other different countries. The Instrumentation control Washers are operated under the guidance of a controller in order to effectively manage and regulate the flow of fluid. This enables precise control over various aspects of the process quality, including but not limited to level, temperature, and pressure, as well as direct control of flow rate.


We are a top notch Duplex Round Bar Supplier, The most asked questions from client is How to choose the right instrumentation manifold Washers. The selection of appropriate instrumentation manifold Washers is of utmost importance in guaranteeing industrial processes’ safety, dependability, and efficiency. In order to arrive at a well-informed decision, it is imperative to carefully contemplate a multitude of pivotal factors.

Firstly, it is necessary to evaluate the application’s specific requirements, including pressure, temperature, and the type of fluid or gas being controlled. Secondly, the valve type, such as needle, ball, or double block and bleed Washers, should be determined based on the desired flow control and shut-off capabilities. The construction material should also be considered, ensuring compatibility with the process media and environment.
