Butterfly Valve Lug Type DIN PN 10
TECHNICAL DESCRIPTION
Butterfly valve, soft-sealing, centric with one-piece “LUG” type stem. The sealing element is a rubber cuff, vulcanized to the body. Top flange according to ISO 5211.
The vulcanized cuff allows the valve to perform its functions even at negative pressure values (vacuum).
WORKING FLUID / MEDIUM
• Fuels, lubricating oil and flammable hydraulic oils,
• Petrol, air, gas, non-flammable hydraulic fluids, boiler feed water, condensate.
• Drinking water
• Sea water.
EXECUTION
• Disc made of stainless steel AISI 316.
• Seal – rubber EPDM or NBR, (FPM/FKM on request).
• Other materials on request.
OPTIONS
• Manual drive
• Gearbox drive
• Electric or pneumatic drive.
Dimensions: DN 200 – 600
The BUTTERFLY VALVE LUG TYPE DIN PN 10 is a high-performance industrial valve designed for reliable flow control in demanding applications. Engineered to meet DIN standards and a pressure rating of PN 10, this valve ensures durability and leak-proof operation in systems handling water, air, chemicals, and other mild corrosive fluids. Its lug-type design allows for easy installation and removal without disrupting the entire pipeline, making it ideal for maintenance and system modifications.Constructed from robust materials such as ductile iron or stainless steel, with a resilient seating (e.g., EPDM or Viton), this valve offers excellent resistance to wear, temperature variations, and pressure fluctuations. It features a manual lever or gear operator for precise flow regulation and is suitable for temperatures ranging from -10°C to 120°C, depending on the seat material. The valve complies with international standards, ensuring compatibility and safety in industrial setups.Key applications include water treatment plants, HVAC systems, chemical processing, and food and beverage industries. Its compact design and lightweight nature reduce installation costs and space requirements, while the lug-type configuration provides enhanced security and versatility for dead-end service or isolation purposes.Conforms to DIN standards for reliability and interoperabilityPressure rating of PN 10 for robust performance in medium-pressure systemsLug-type design facilitates easy maintenance and pipeline isolationAvailable in various sizes and materials to suit specific industrial needsSuitable for on/off and throttling applications with minimal pressure drop
