DUYAR Lug Type Butterfly Valve DN65

DUYAR Lug Type Butterfly Valve DN65: Reliable Control with Stainless Steel Valve

The DUYAR Lug-Type Butterfly Valve is a high-performance valve designed to control the flow of fluids (water, air, gas, wastewater, etc.) in industrial installations and provide end-of-line isolation. Offered by DUYAR, one of Turkey's leading valve manufacturers, this product stands out with its durable material construction and lug-type connection advantages.

This valve is used on medium-sized lines with a nominal diameter of DN65 (2 1/2 in) .

What is a Lug Type Butterfly Valve and What Are Its Advantages?

A lug-type butterfly valve is a type of valve with threaded holes (lugs) on both sides of its body. This design secures the valve between two flanges with bolts and offers its most significant advantage:

• Easy Maintenance and End-of-Line Isolation: Lug-type butterfly valves can be bolted to a single flange and used as end-of-line blanking valves . This allows one side of the line to remain pressurized while the other is disconnected.

• Durable Structure: The body is generally produced from materials such as GGG40 Ductile Iron or GG25 Gray Cast Iron (Iron Casting).

Butterfly Valve Features and Technical Details

• Nominal Diameter: DN65 (2 1/2 inches).

• Connection Type: Lug Type (suitable for PN 16 connections in accordance with TS EN 1092-2 standards).

• Valve (Disc) Material: Stainless Steel (usually AISI 304). This increases corrosion and chemical resistance.

• Gasket Material: EPDM (Ethylene Propylene Diene Monomer). EPDM has high resistance to water, hot water, steam and light chemicals.

• Maximum Working Pressure: PN16 (16 bar) pressure class.

• Maximum Operating Temperature: With EPDM seal, it generally operates safely between -10 °C and +120 °C .

• Leakage Test: RATE-A (Zero leakage) test is applied according to EN 12266-1 Standard.

• Control Type: It can be controlled by lever control, reducer, pneumatic or electric actuators.

Butterfly Valve Usage Areas

• Heating, ventilation and air conditioning (HVAC) systems.

• Water treatment and distribution systems.

• Shipbuilding and drilling facilities.

• Food and chemical enterprises (Stainless steel valve advantage).

• Fire extinguishing systems, water, sea water, dust, gas and wastewater lines.
