Our butterfly valves are designed for tight shutoff, dependable performance, and long service life in both standard and severe-service environments.

With extensive experience supporting EPC contractors, plant operators, and OEMs, SVR Global supplies butterfly valves that meet stringent project specifications and internationally recognized industry standards.

Quick Definition: A butterfly valve is a quarter-turn rotary valve that uses a rotating disc to start, stop, or throttle flow in a pipeline, offering compact and cost-effective flow control for large line sizes.

What Is a Butterfly Valve?

A butterfly valve is a quarter-turn rotary valve that regulates or isolates fluid flow using a rotating disc positioned in the center of the pipeline. When the disc rotates 90 degrees, it either allows full flow or completely shuts off the line. Butterfly valves can be manually operated or automated using pneumatic, electric, or hydraulic actuators for precise flow control.

Where Are Butterfly Valves Used in Industrial Systems?

SVR Global butterfly valves are widely used across critical industrial flow applications, including:

• Flow isolation and regulation in oil & gas pipelines and processing units
• Water treatment, desalination, and distribution networks
• Cooling water and process systems in power generation plants
• Chemical and petrochemical processing facilities
• Industrial utilities, infrastructure, and pumping stations

These applications require valves with reliable sealing, fast operation, and minimal pressure loss to maintain process efficiency and system reliability.

Types of Butterfly Valves

SVR Global manufactures and supplies a complete range of butterfly valve designs to meet diverse service conditions:

Wafer Butterfly Valves

Lightweight and compact valves installed between flanges, ideal for space-constrained piping systems and general-purpose isolation.

Lug Type Butterfly Valves

Designed for dead-end service, allowing downstream pipe removal or maintenance without disturbing the upstream line.

Double Offset Butterfly Valves

Feature reduced seat wear and improved sealing performance for moderate to high-pressure applications and frequent cycling.

Triple Offset Butterfly Valves

Metal-to-metal seated valves engineered for tight shutoff in high-temperature, high-pressure, and severe-service pipelines.

High-Performance Butterfly Valves

Designed for demanding oil & gas, chemical, and offshore environments requiring enhanced durability, tight sealing, and precise control.

Butterfly Valve vs Other Valve Types

Butterfly Valve vs Gate Valve

Butterfly valves offer compact size, lower weight, and faster quarter-turn operation, while gate valves provide full-bore isolation but require more space and operating time.

Butterfly Valve vs Ball Valve

Ball valves provide bubble-tight shutoff and are ideal for critical isolation, whereas butterfly valves are more economical and space-efficient for large-diameter pipelines and general throttling.

Butterfly Valve vs Control Valve

Butterfly valves are used for isolation and throttling of flow, while control valves are engineered for precise modulation of process variables such as flow, pressure, and temperature under closed-loop control.

How to Choose the Right Butterfly Valve

Selecting the correct butterfly valve depends on:

• Operating pressure and temperature
• Type of fluid (water, oil, gas, chemicals)
• End connection requirements (wafer, lug, or flanged)
• Required shutoff performance and leakage class
• Compliance with API, ANSI, or DIN standards

For high-pressure or severe-service conditions, double or triple offset butterfly valves are recommended to ensure tight sealing and long-term reliability.

Butterfly Valve FAQs

What is a butterfly valve used for?

Butterfly valves are used for flow isolation and throttling in pipelines carrying liquids, gases, and industrial fluids across water, oil & gas, chemical, and power applications.

How does a butterfly valve work?

Rotating the disc by up to 90 degrees opens or closes the flow path. In the open position, the disc is aligned with the flow; in the closed position, it seals against the seat to stop flow.

Which butterfly valve is best for oil and gas applications?

Double or triple offset butterfly valves are ideal for oil and gas applications due to their metal seats, durability, and tight sealing under high pressure and temperature.

When should I use wafer vs lug butterfly valves?

Wafer butterfly valves are suitable for general isolation between flanges, while lug butterfly valves are preferred for dead-end service or where downstream piping may need to be removed for maintenance.
