Butterfly Valve Lug Type DIN PN 16

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


Description

The Lug Type Butterfly Valve DIN PN16 is engineered for high-performance industrial applications requiring secure, leak-proof flow control. Designed in compliance with DIN standards, this valve features a robust lug-style body that allows for easy installation and removal without disrupting the entire pipeline system. Its construction ensures durability under pressures up to PN16, making it ideal for water treatment, chemical processing, and HVAC systems.Key features include a corrosion-resistant disc and seat materials, such as EPDM or Viton, which provide excellent sealing and longevity even in aggressive media. The valve operates with a simple 90-degree turn, enabling quick shut-off or regulation of fluids. Its compact design saves space and reduces overall system weight, while the lug configuration permits dead-end service and enhances safety during maintenance.Complies with DIN standards for reliability and interoperabilityPressure rating of PN16 for medium to high-pressure applicationsLug-type design facilitates easy mounting and disassemblyAvailable in various materials like stainless steel, ductile iron, or coated finishesSuitable for temperatures ranging from -20°C to 120°C, depending on seat materialThis valve is an essential component for engineers and procurement specialists seeking efficient, cost-effective solutions in fluid handling systems. Optimize your operations with this dependable butterfly valve, designed to minimize downtime and maximize performance in demanding environments.
