The valve body, valve plate and valve stem of the lug butterfly valve are all finished, so its torque is very small. In addition, the lug type butterfly valve has strong parts interchangeability, so its maintenance is very simple. There are three sealing rings on the stem of the lug butterfly valve, which can prevent the medium from flowing out through the stem and cause leakage.
Lug style butterfly valves are versatile valves used in diverse industries for fluid flow control. They are notably suitable for water and wastewater treatment plants, HVAC systems, the food and beverage industry, chemical and petrochemical sectors, power generation, oil and gas operations, marine applications, pulp and paper production, chemical transport, and mining processes. Their compact design allows for easy installation between flanges, making them ideal for space-constrained environments. These valves offer reliable shut-off and flow control, making them essential in systems that require precision and efficient regulation. When selecting lug butterfly valves, factors like fluid type, operating conditions, temperature, pressure, and material compatibility should be considered to ensure optimal performance and longevity in the intended application.
