LUG TYPE BUTTERFLY VALVE
Supplier: Krishna Industries, Ahmedabad, Gujarat, India
Minimum Order Quantity (MOQ): 10 Nos

INTRODUCTION

A Lug Type Butterfly Valve is one of the most versatile and widely used flow control valves in Indian industrial piping systems. Designed for tight shut-off, easy installation, and long operational life, this valve is especially suitable for industries that require frequent maintenance, isolation, or sectional pipeline control. Krishna Industries, based in Ahmedabad, Gujarat, India, supplies high-quality Lug Type Butterfly Valves to industries across India, supporting applications in water supply, chemical processing, HVAC systems, fire protection, irrigation, power plants, sugar mills, cement plants, pharmaceuticals, and general engineering sectors.

The Lug Type Butterfly Valve stands apart due to its threaded lug inserts around the valve body, which allow it to be bolted directly to pipe flanges without the need for nuts. This feature enables the valve to be installed at the end of a pipeline or removed from one side without disturbing the other side of the piping system. Compared to wafer type butterfly valves, lug type valves offer higher mechanical strength, better alignment, and improved safety during maintenance.

At Krishna Industries, our Lug Type Butterfly Valves are manufactured and supplied with strict quality control, using robust materials such as cast iron, ductile iron, carbon steel, stainless steel, and premium-grade elastomer seats like EPDM, NBR, Viton, or PTFE. These valves are compatible with manual lever operation, gear-operated mechanisms, and actuator mounting for automation, making them suitable for a wide range of Indian industrial requirements.

WHAT IS A LUG TYPE BUTTERFLY VALVE

A Lug Type Butterfly Valve is a quarter-turn rotary valve used to regulate, isolate, or control fluid flow. The valve consists of a circular disc mounted on a rotating shaft. When the disc is parallel to the flow, the valve is fully open; when perpendicular, the valve is fully closed.

The defining feature of a lug type butterfly valve is the presence of threaded lugs on the outer circumference of the valve body. These lugs match the bolt holes on standard pipe flanges, allowing the valve to be installed without through-bolting. This design makes lug type butterfly valves ideal for dead-end service and for systems where one side of the pipeline may need to be removed while maintaining pressure on the other side.
