What is a Butterfly Valve and How Does It Work?
A Butterfly Valve is a quarter-turn rotational valve used to regulate, start, or stop the flow of fluids in a pipeline. It consists of a circular disc mounted on a shaft positioned at the center of the pipe. When the valve handle or actuator rotates the shaft, the disc turns either parallel or perpendicular to the flow. When the disc is parallel to the pipeline, fluid flows freely through the valve. When it is turned perpendicular, the disc blocks the passage and stops the flow completely.
Butterfly valves are widely preferred in industrial systems because of their compact design, lightweight construction, and quick operation. They require minimal space compared to many other valve types and can be easily automated using pneumatic or electric actuators. Due to their efficiency and cost-effectiveness, butterfly valves are commonly used in water treatment plants, chemical processing units, HVAC systems, and oil and gas pipelines where reliable flow control is required.

FAQ’s
Have a question before you buy our products? Take a look at the FAQs below.
If you don’t find the answer you’re looking for, get in touch with us here.
- What is a butterfly valve and how does it work?
- What types of butterfly valves does Freture Techno manufacture?
Concentric design, single offset, double offset, and PTFE/PFA/FEP lined butterfly valves, in wafer, lug, and flanged end connections.
- What's the difference between concentric and double offset butterfly valves?
In a concentric valve the shaft runs through the center of the disc, which stays in constant contact with a resilient seat — suited to lower-pressure service. In a double offset valve, the shaft is offset from both the disc and body centerline, lifting the disc off the seat during rotation. This cuts friction and wear, giving better sealing life at higher pressures and temperatures.
- What standards do these valves comply with?
Design to API 609 and EN 593, face-to-face to MSS SP-67 and ISO 5752, with end connections per ASME B16.5 and EN 1092.
- What size and pressure range is available?
50NB to 600NB (2"–24"), pressure classes #150 to #600, rated for -20°C to 200°C depending on seat and lining material.
- What materials are used in construction?
Body and disc in carbon steel, stainless steel, or cast iron; seat materials include EPDM, NBR, FKM, and PTFE depending on the service media.
- When should I choose a PTFE Lined Butterfly Valve over a standard one?
For corrosive or high-purity media — acids, chemicals, pharma-grade fluids — where the metal body needs full isolation from the process fluid. Standard concentric or offset valves are for general water, air, and non-corrosive service.
- Which industries use these valves?
Water and wastewater treatment, HVAC, chemical processing, oil and gas pipelines, and power generation.
- Are these valves fire-safe and suitable for sour service?
Yes — fire-safe design per API 607/ISO 10497, and NACE MR0175-compliant materials are available for sour (H2S) service on request.
- Why choose Freture Techno for butterfly valves?
ISO 9001:2015 certified manufacturing, in-house engineering support, and Material Test Certificates / Certificate of Compliance supplied with every order.
