    FAQs

    What is flange butterfly valve?

    A flange butterfly valve is a type of flow control device that provides precise shutoff and regulating capabilities for handling liquid and gas applications. This type of valve consists of a cylindrical body made up of two pieces, the disc and the stem. The disc has an attached rod or stem which passes through the seating material in order to actuate the device’s opening or closing action.

    When fully open, this valve allows fluid to pass through quickly due to its unobstructed design. When partially open (in throttling position), it acts like a throttle providing very efficient flow regulation capabilities compared to other types valves such as gates, globes, plug valves etc.. As well as controlling flow rate, this can also be used as an on/off switch allowing full isolation from line when closed.

    Flange butterfly valves are usually paired with either screw-type actuators or pneumatic cylinders depending upon application requirements and can also be fitted with electrical actuators where automation is required. A key benefit of these valves is their ability to have multiple connection points along their clip ring (body) which allows fitting for various types of piping systems such as butt welded ends or socket welded connections. They are often used in larger industries for applications within water treatment facilities, power plants & chemical industry where large pipe sizes require rigorous shut offs without risking leakage due to pressure buildup caused by the increased volume & velocity at high rates of flow.

    What are the applications of flange butterfly valves?

    Flange butterfly valves are widely used in a variety of applications because they offer maximum flexibility with minimum weight. These valves feature a lightweight, cylindrical body and an angled disc that allows for instant throttling or on/off control within a piping system. For this reason, flange butterfly valves are commonly used in water treatment systems, chemical processing facilities, petroleum refineries, natural gas pipelines and other industrial operations.

    One of the most important applications of flange butterfly valves is their ability to regulate flow rate and pressure within pipes without having to create costly modifications. Because opening or closing the disc requires minimal force against its stem (or shaft), these devices can be operated manually or with automated actuators such as solenoids or motors for greater process efficiency. This makes them ideal for modulating liquids and gases over varying temperatures while ensuring precise operation every time.

    What are the tests for flange butterfly valves before leaving the factory?

    Before any flange butterfly valves are allowed to leave the factory, they must pass a series of tests in order to make sure that they are safe and reliable. Typically, these tests include:

    • Visual Inspection- A visual inspection is done in order to ensure that each valve is aesthetically sound with no visible damage or deformity. In addition, this inspection ensures proper fitment when it comes time to install the valve into its application area.

    • Test Pressure Rating- All valves must have their rated test pressure tested against in order to ensure they meet regulatory requirements and can safely handle the system it will be installed in. This helps prevent excess pressure conditions which can lead to structural failure or injury.

    What are the functions and voltages of flange butterfly valve electric actuators?

    Flange butterfly valve electric actuators are used to control the opening and closing of valves. These actuators work by converting electrical energy into mechanical motion, allowing for precise control over the valve’s operation. The actuator is typically powered by either 120VAC or 24VDC, though larger models may require higher voltages for maximum performance. When voltage is applied, the motor within the actuator will turn a crank shaft which in turn rotates the valve stem in order to open or close it.

    The primary function of flange butterfly valve electric actuators is to provide manual override capabilities so that they can be adjusted from a remote location without needing physical access to the site where it is installed. This allows operators greater control when changes need to be made quickly and easily, such as during an emergency situation or necessary maintenance activity. Additionally, these valves can also be programmed with pre-defined parameters so that they operate automatically according to preset rules and conditions without requiring manual adjustment at all times.
