Why ISI Marked Butterfly Valves are the Gold Standard for Industrial Flow Control

In industrial piping, the Butterfly Valve is often the unsung hero. It’s compact, cost-effective, and versatile. However, not all valves are created equal. For industries where safety and precision are non-negotiable, the ISI Mark (IS 13095) isn’t just a label—it’s a guarantee of performance.

At OSKO Valves, our butterfly valve range is engineered to outperform standard industry expectations, providing a leak-proof seal and long-term durability.

What Makes an ISI Marked Butterfly Valve Different?

When you see the ISI mark on an OSKO valve, it means the product has undergone rigorous testing for:

• Shell Strength: Ensuring the body can handle pressures well above the rated limit.
• Seat Leakage: Testing for zero-drop leakage to prevent fluid loss.

Technical Spotlight: The OSKO Butterfly Valve Range

We offer several configurations tailored to specific industrial environments:

1. Wafer Type Butterfly Valves

The most common choice for space-saving installations. It is clamped between pipe flanges, making it ideal for water distribution and HVAC systems.

2. Lug Type Butterfly Valves

Designed with threaded inserts, these allow for “Dead-End Service,” meaning you can disconnect the downstream piping while the valve remains under pressure.

The Shift to Automation: Pneumatic & Electric Actuators

Manual levers are reliable, but modern plants require Valve Automation. OSKO specializes in integrating butterfly valves with:

• Pneumatic Actuators: Ideal for rapid “On-Off” action in chemical and water treatment plants.
• Electric Actuators: Best for remote locations where compressed air is unavailable, offering precise flow modulation.

Pro Tip: Choosing a valve with an ISO 5211 Mounting Pad (standard on OSKO valves) ensures you can upgrade from manual to automated control at any time without replacing the entire unit.

Key Applications: Where OSKO Excels

Our butterfly valves are currently optimized for:

• Water Treatment (STP/ETP): Handling sludge and treated water with ease.
• Firefighting Systems: Reliable, fast-acting flow control when it matters most.
• HVAC & Chilled Water: Regulating temperature efficiently in commercial buildings.
• Pharma & Food Processing: Utilizing high-grade Stainless Steel (CF8/CF8M) discs for hygiene.

Selecting the right seat material (EPDM vs. Nitrile) or disc grade (CI vs. SS) can be the difference between a valve lasting 10 years or 10 months.
