What is a Stainless Steel Butterfly Valve?
A stainless steel butterfly valve is a quarter-turn rotational motion valve that regulates, isolates, or controls fluid flow using a rotating disc. These valves are ideal for applications that require quick shutoff, compact design, and lightweight construction.
Made from SS 304, SS 316, and other high-grade alloys, our valves provide excellent corrosion resistance, hygiene, and mechanical strength — making them perfect for industries such as:
Dairy & Food Processing
Pharmaceutical
Chemical & Petrochemical
HVAC & Water Treatment
Oil & Gas
Power Plants
Butterfly Valve Working Principle
The working principle of a butterfly valve is simple: when the actuator turns the disc (or “butterfly”) 90 degrees, the valve goes from fully open to fully closed. This quick operation makes it suitable for systems requiring frequent opening and closing or throttling flow.
Open Position: Disc is parallel to the flow
Closed Position: Disc is perpendicular to the flow
Partially Open: Used for regulating flow rate

Butterfly Valve Diagram
A butterfly valve diagram typically includes:
Body – Main casing housing the valve components
Disc – Rotating element that controls flow
Stem/Shaft – Connects the disc to the actuator
Seat – Sealing mechanism ensuring leak-free operation
Actuator – Manual handle, gear, pneumatic or electric actuator
Butterfly Valve Actuator Options
We offer both manual and automated actuator options:
Manual Lever / Gear Operated
Pneumatic Actuators – Fast, efficient actuation
Electric Actuators – Programmable, remote-controlled
Hydraulic Actuators – For high-force applications
Each actuator is tested for torque, sealing performance, and response time to meet your system requirements.

Butterfly Valve Symbol (Used in P&ID Diagrams)
Butterfly valve symbols are essential for the accurate interpretation of technical drawings such as Piping and Instrumentation Diagrams (P&IDs), which depict the layout and function of a piping system. These symbols provide vital information about the valve type, configuration, and any actuation mechanisms. Misinterpreting these symbols can lead to design flaws, improper installation, and costly errors during operation.
Standard Butterfly Valve Symbols
The basic symbol for a butterfly valve typically includes:
Vertical line – Valve body
Diagonal line – Disc
Solid circle – Stem
Horizontal line – Pipe
Butterfly Valve in P&ID Context
In P&ID diagrams, butterfly valves may be shown in these configurations:
Open Valve – Disc is parallel to the flow
Closed Valve – Disc is perpendicular to the flow
These schematic representations help engineers quickly identify the valve’s status and location.
International Standards for Butterfly Valve Symbols
ISO Standards (Global)
ISO 10628 and ISO 14617 define standard valve symbols, ensuring clarity in global engineering drawings.
ANSI/ASME Standards (North America)
ANSI/ASME Y32.2-1975 provides symbol standards for valves used in piping systems, widely accepted across the USA and Canada.
DIN Standards (Europe)
DIN 19227 outlines symbol representation for valves in engineering documentation, primarily used in Germany and across the EU.
Special Symbols for Actuated Butterfly Valves
Pneumatic Actuated Butterfly Valve Symbol: Includes actuator icon with lines indicating pneumatic control.
Electric Actuated Butterfly Valve Symbol: Shown with a motor symbol atop the valve.
Hydraulic Actuated Butterfly Valve Symbol: Depicted with hydraulic control symbols.
Each symbol provides clear communication to operators, designers, and technicians involved in installation and maintenance.
Flanged Type Butterfly Valve
Flanged butterfly valves are bolted between two flanged pipe ends and are suitable for high-pressure and critical applications. Benefits include:
Easy installation and removal
Strong sealing
Corrosion resistance with SS304/SS316 body
Ideal for water treatment, chemical plants, and HVAC
Butterfly Valve Function and Benefits
The function of a butterfly valve is to regulate, isolate, or throttle the flow of fluids. Key benefits include:
Fast 90° turn operation
Compact size and lightweight design
Suitable for large volume flows
Versatile across industries and media types
Lower maintenance cost
