Pneumatic Actuated Butterfly Valve DN100

Pneumatic Actuated Butterfly Valve DN100 (Lug Type): Superior Durability in Automatic Control

The Pneumatic Actuated Lug-Type Butterfly Valve DN100 is a high-performance valve solution designed to quickly, safely, and automatically control the flow of fluids (water, gas, wastewater, chemicals) in industrial installations. With its DN100 (4 in) nominal diameter and Lug-type connection, it is ideal for medium/large diameter lines.

This configuration combines the robust construction of a butterfly valve with the fast response time of a pneumatic actuator.

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

A lug type butterfly valve is a type of valve that is connected between two flanges in the pipeline by bolts, but the bolts are screwed directly into threaded lugs (Lugs) on the valve's body.

Importance of Lug Type:

• Easy Maintenance: This allows one side of the line to remain pressurized even if the other side is disconnected. This eliminates the need to drain the entire system during valve maintenance or replacement.

• Solid Mounting: Secures the valve firmly to the pipeline.

Double Acting Pneumatic Control

• Double-Acting Actuator: Uses compressed air to both open and close the valve. This provides more precise control and faster response time than single-acting (spring-return) models.

• Automatic Control: With actuator support, this valve enables fast and remote ON-OFF control by integrating into automatic systems.

Pneumatic Actuated Butterfly Valve Technical Specifications and Material Structure

• Nominal Diameter: DN100 (4 inches).

• Pressure Class: Generally resistant to pressures up to PN10 or PN16 .

• Material Structure (Example Ayvaz KV-8):

  • Body: GG25 Cast Iron (or GGG-40 Nodular Cast Iron).

  • Valve (Disc): AISI 304/316 Stainless Steel or GGG40.3 Nickel Coated Ductile Iron . The stainless valve provides superior resistance, especially for chemical and corrosive fluids.

  • Shaft: AISI 420 Stainless Steel.

• Temperature Range: Depending on the material structure, it can operate efficiently between -10°C and +130°C .

• Actuator Supply: Double acting actuators typically operate with 4-6 Bar air pressure.

Pneumatic Actuated Butterfly Valve Usage Areas

• HVAC and Water Systems: Water, seawater, wastewater and air lines.

• Industrial Processes: Automatic flow control in the chemical, food, shipbuilding, oil and gas industries.

• Fire Extinguishing: Safe control mechanisms in fire systems.
