    Product Description
    With the help of our employees, we have been able to offer an excellent range of Butterfly Valves. We are highly enriched with advanced resources which are utilized in order to design the offered products as per the latest market trends. Manufactured with premier-grade components and other raw material, these products are highly suitable for the industrial applications. Owing to their excellent performance, perfect finish and high tensile strength, these products are highly demanded in the market.

    Installation Of Butterfly Valve

    There are a few installation checklist to follow:

    • Be assured that the temperature and pressure will be within the limits of the product's intended capacity while it is being installed.
    • The construction material of the valve should be compatible with the chemicals of the media/fluid flowing through the pipeline.
    • Valve ends and piping should be clean and free of defects. You should check this out.
    • Sufficient free space is important for valve installation. To do this, check the distance between the pipe edges.
    • In order to lift larger valves, the material of the butterfly valve must be perfect and suitable.
    • The pipe size should match the inlet and outlet size measurements and the dimensions of the unit to be installed. Add support if the pipe is straining (which happens due to the weight).
    • We recommend 6 diameters from the top of the butterfly valve and approximately 4 diameters from the bottom for a secure installation.

    Maintenance of Butterfly Valves

    Butterfly valves should be well maintained to prevent rust and grease. Follow below points:

    • There is a grease nipple on the top of the valve. This is not observable when the valve arrives. Grease the bonnet periodically until excess grease runs out.
    • For maintenance, the gearbox can be lubricated with lithium-based grease.
    • All parts of the valve can be easily cleaned using silicone based products/lubricants.
    • If not used regularly, twist or turn the butter valve once a month.

    Frequently Asked Questions:

    1. How long do butterfly valves last?

    Ans: Generally, the service life of a typical rubber seal valve seat is about 15-20 years, and the service life of a metal seal valve seat is about 80-90 years.

    2. Do butterfly valves need lubrication?

    Ans: If your system's butterfly valves operate in a dry environment, lubrication may be required for proper functioning of internal parts. Ensuring that the discs and seats are lubricated significantly increases their service life.

    3. Does flow direction matter in butterfly valve?

    Ans: Butterfly valves can be bi-directional, but there is a preferred direction of flow marked on the body of the valve. However, it is highly recommended to install the valve in the preferred flow direction as this will prolong valve life and reduce the torque required to actuate the valve.

    4. How much pressure can a butterfly valve hold?

    Ans: Its heat tolerance is 1200 degree fahrenheit as it can withstand 1,480 PSI of pressure

    5. How do you fix a leaky butterfly valve?

    Ans: If there is a leak between both the actuator and the butterfly valve, clean the packing hole and replace the packing if necessary. If the valve is difficult to actuate or actuate, lubricate the actuator, wipe the seat and stem and replace. Also, use thread skip or loctite when tightening the screws.

    6. How do I know if my butterfly valve is closed?

    Ans: Butterfly valves have a lever handle to indicate if there is flow. Open the valve by turning the handle half a turn. To close the valve, turn the handle perpendicular to the stem. The lever should be parallel to the spindle when the butterfly valve is closed.

    7. What is the main disadvantage of butterfly valves?

    Ans: Isolation valves are not optimally designed to handle mixed dry materials. Abrasive, dry bulk materials can damage them and can erode the valve to the point that it no longer provides an effective seal and must be replaced.

    8. What makes a butterfly valve high performance?

    Ans: High performance butterfly valves are called double offset because they use discs that are offset from the center of the seat. In this configuration the disc is eccentric or offset from the valve seat. When the disc starts spinning, it's off the seat instead of on top of it.

    9. Do butterfly valves leak?

    Ans: Butterfly valves have a permissible leakage tolerance, which may vary depending on the application. While zero leakage sounds desirable, from an engineering standpoint this is not always the case and many butterfly valves will eventually leak. This is especially true when the medium is a gas such as helium.
