How can we fix WRAS butterfly valve?

Publish Time: 2022-04-29     Origin: Site

WRAS butterfly valves are throttling valves that turn in a quarter-turn rotary motion. WRAS butterfly valves control the media flow in a system. The operators use these WRAS butterfly valves in different media and applications. When you operate a WRAS butterfly valve, it has a similar principle to a ball valve, that allows a fast shut off.

What is the working principle of WRAS butterfly valve?

The WRAS butterfly valve operates based on the quick shut off principle. The circular disc (butterfly) of the WRAS butterfly valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the WRAS butterfly valve. Using the handwheel, the metal disc is rotated to keep the disc parallel or perpendicular to the flow and it allows or closes the flow. So, the operating principle of the WRAS butterfly valves is fairly simple.

The WRAS butterfly valve is one of the few industrial valves that are both efficient in isolating and regulating the flow of media. The WRAS butterfly valve is also quick to open. The disc is attached to the stem, either through the former or the stem is at the back of the disc. The stem is attached to the handle that is either placed on top of the body or at its side.


What are the characteristics of WRAS butterfly valve?

WRAS butterfly valve is small in size and light in weight. In comparison with traditional ball valves and gate valves, butterfly valves save at least 70% of space and weight.

WRAS butterfly valve is easy to install and maintain. WRAS butterfly valve can be mounted wherever needed.

WRAS butterfly valve has simple and compact construction, which can on-off quickly at 90 degrees.

Compared to ball valve and gate valve, WRAS butterfly valve is great energy saver with lesser torque operations.

WRAS butterfly valve has stable anti-corrosion performance because of bubble-tight sealing resulting to no leakage under the pressure testing.

WRAS butterfly valve has wide selection of material, such as DI, carbon steel, stainless steel, super duplex, or alloy material. All are applicable to various mediums.

The material of replacement parts of WRAS butterfly valve can be applied to various media.

The WRAS butterfly valve can be equipped with pneumatic and electric devices according to requirements to meet needs of remote control and program control.


How can we fix WRAS butterfly valve?

For the installation of the WRAS butterfly valve, it must be laid flat before installation. Remember not to bump WRAS butterfly valve at will. After it is drawn to the installation length during installation in the design of the on-site pipeline, it is not be allowed to disassembled the WRAS butterfly valve at will. The WRAS butterfly valve can be installed in any position. After the it is installed, the WRAS butterfly valve needs to be laid along the line. A bracket is made for the WRAS butterfly valve. Once the bracket is made, it is strictly forbidden to remove.

When installing the WRAS butterfly valve, if the WRAS butterfly valve does not perform temperature compensation, only installation and replacement are not enough. Once you install the WRAS butterfly valve, pay attention to its screw and screw limit. At the same time, it is necessary to record the size and diameter of the screw, as well as the force WRAS butterfly valve can withstand. After these records are complete and standardized, you must not repeatedly lift the screw. Check whether the installation is completed depends on whether both sides of the pipeline are parallel.


Learn more something about WRAS butterfly valve can know the characteristics of WRAS butterfly valve and how to fix WRAS butterfly valve. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd.
