Cast Iron (CI) Butterfly Valve Full Lug Type PN10

Product description

What is a CI Butterfly Valve?

A CI butterfly valve (Cast Iron Butterfly Valve) is a control valve which can be used to isolate or regulate flow. The valve operates with a disc fixed through a stem in the body of the valve.

Operation of a CI Butterfly (BF) Valve

Butterfly valves, like any other control valves, use an obstruction component. In this type of valve, a disc is used which is operated with a lever, gear, or actuator on top. This disc is attached to the upper control with a stem which goes from the center of the disc. CI butterfly valves sometimes use ring gaskets of softer material to provide leak-proof operation.

Benefits of using a CI Butterfly (BF) Valves

CI butterfly valves are compact as compared to other types of control valves or mechanical valves. Its compact size makes it very easy to install as well. One of the key benefits of using this type of valve is its effect on the pressure. As the disc when opened sits perpendicular to the media, it does not reduce the pressure or flow of the media to a significant extent.

What is a Lug Type Butterfly Valve?

Lug type butterfly valves are generally made of cast iron or ductile iron. They contain lugs threaded inside all over their body for easier installation with flanges. Additionally, when sandwiched between flanges, this type of valve—including the CI butterfly valve version—can match the flange screw holes and fit perfectly over a pipeline.

Lug type butterfly valves can be used for various industries such as water, chemical, HVAC, fire, food processing, shipbuilding, drainage, petroleum, etc.

FAQs for Cast Iron (CI) Butterfly Valve Full Lug Type PN10:

Q1: What makes a CI butterfly valve suitable for PN10 pressure applications?
A ci butterfly valve is built with strong cast iron construction that can withstand PN10 pressure ratings, offering reliable shutoff and smooth flow control in industrial water, HVAC, and utility pipelines.

Q2: Can a CI butterfly valve full lug type be used for isolation in pipelines?
Yes, a full lug ci butterfly valve allows isolation of either side of the pipeline during maintenance, making it ideal for systems that require section-wise shutoff without disturbing the entire line.

Q3: Is installation of a CI butterfly valve full lug type easy in existing piping systems?
A ci butterfly valve with a full lug design is easy to install because it can be mounted between flanges using bolts on both sides, ensuring a secure and stable connection in any pipeline setup.

Q4: How much maintenance does a CI butterfly valve require during operation?
A ci butterfly valve typically needs minimal maintenance, usually limited to checking the rubber seat, inspecting the disc movement, and ensuring smooth operation for long-term reliability.
