Product Description
Handle Valves are those valves that operate through a manual operator (such as handwheel or hand lever). Handle valves are primarily used to stop and start the flow (block or on-off valves), although some designs can be used for basic manual throttling.
Handle valves are a type of valves operated by handles or hand wheels and commonly used on equipment and devices. Generally, rotating the handle or hand wheel clockwise will turn off the valve while rotating anticlockwise will turn on the valve
Versatile Material ChoicesThe lug type butterfly valve is produced using a range of durable materials such as stainless steel, brass, PVC, alloy, rubber, and ceramic. This broad selection ensures chemical resistance, mechanical strength, and longevity, accommodating varied installation environments and water conditions for both domestic and industrial uses.
Wide Range of SizesThese valves are available in sizes from 40mm to 350mm, making them suitable for small-scale pipelines as well as larger industrial systems. The diverse sizing options allow for precise flow control and efficient integration into existing water distribution frameworks.
Manual Operation for Reliable ControlAs a hand-operated valve, the lug type butterfly valve offers simple and effective manual control without the need for electrical or pneumatic power sources. This ensures dependable performance even in locations where automatic solutions are impractical or unavailable.
FAQs of Hand Operated Butterfly Valve:
Q: How is a hand operated butterfly valve installed and maintained?
A: Installation involves aligning the lug type valve between pipe flanges, then securely fastening it using appropriate bolts. Maintenance typically requires periodic inspection for leaks, cleaning of internal surfaces, and lubrication of moving parts, ensuring optimal operation.
Q: What are the benefits of using a lug type butterfly valve for water applications?
A: Lug type butterfly valves provide quick shut-off and precise flow regulation. Their design allows for easy installation and removal from pipelines, while the availability of various materials ensures adaptability to different water qualities and system pressures.
Q: When should I choose a manually operated butterfly valve over an automated one?
A: Manual valves are preferable when power sources are unavailable, simplicity is needed, or infrequent adjustments are expected. Theyre ideal for low-maintenance settings or locations where automation isnt practical or cost-effective.
Q: Where can I source these valves in India?
A: Hand operated lug type butterfly valves are readily available from dealers, distributors, exporters, fabricators, manufacturers, retailers, suppliers, traders, and wholesalers across India, catering to diverse customer requirements.
Q: What is the process of operating a hand operated butterfly valve?
A: Operation involves turning the hand lever or wheel to rotate the valve disc, which controls the flow of water through the pipeline. Full rotation opens or closes the passage, allowing for stepped or complete shut-off as needed.
Q: How do the various material options influence valve usage?
A: Material selection impacts corrosion resistance, pressure rating, and durability. For example, stainless steel and ductile iron are suited for high-pressure systems, while PVC and plastic work well for lighter-duty or corrosive water conditions.
