API 609 BV-10 Butterfly Valve
Butterfly valves play a vital role in modern piping systems, operating with a rotating disc located on a vertical axis as the closing element. The API 609 BV-10 Butterfly Valve features a disc structure that rotates around its axis to open or close the pipeline. This design allows the valve to be opened and closed quickly and easily. ORFA Industrial Products Industry and Trade Inc. offers butterfly valves that meet high quality standards.
The API 609 Butterfly Valve is a product that stands out for its sealing performance and durability. The valve's sealing is achieved between the metal cover and the elastic or plastic sealing elements lining the inside of the body. This sealing element also acts as a gasket on the flange between the valve and the pipe, providing an additional seal. The API 609 Butterfly Valve stands out for its low pressure loss, easy opening and closing mechanism, excellent sealing, lightweight design, and compact design.

The API 609 BV-10 Butterfly Valve is a modern and efficient valve type designed to control flow in piping systems. The basic operating principle of these valves is based on the action of a rotating disc used as a closing element. Here is a detailed explanation of the BV-10 Butterfly Valve's operating principle:
API 609 BV-10 Butterfly Valve Working Principle
The API 609 BV-10 Butterfly Valve is a modern and efficient valve type designed to control flow in piping systems. The basic operating principle of these valves is based on the action of a rotating disc used as a closing element. Here is a detailed explanation of the BV-10 Butterfly Valve's operating principle:
Disc and Body Structure
The disc, the most important component of butterfly valves, is located at the center of the valve and is connected to a shaft. In the API 609 BV-10 model, this disc is made of AISI 316 stainless steel, offering high corrosion resistance. The valve body is made of ASTM A216 WCB cast steel, ensuring durability and long service life.
Sealing Mechanism
The valve's sealing element, located between the disc and body, is made of EPDM. This seal prevents leakage when the valve is closed and also acts as a gasket between the valve and the pipe flange. EPDM provides excellent sealing over a wide temperature range and is resistant to chemicals.
Opening and Closing Mechanism
The API 609 BV-10 Butterfly Valve opens and closes by rotating the disc 90 degrees around its axis. This rotation is achieved by using a valve stem, handwheel, gearbox, or actuator. The disc completely opens or closes the flow path within the valve body.
Open Position: The disc becomes parallel to the flow path, creating minimal obstruction to the flow. In this position, flow is nearly free and pressure loss is minimal.
Closed Position: The disc becomes perpendicular to the flow path, completely stopping the flow. In this position, a tight contact is made between the disc and the seal, preventing leakage.
Control and Adjustment
Butterfly valves allow precise control of flow. The disc's opening angle determines the flow rate and amount. Partial opening positions allow flow to be adjusted to desired levels between full closure and full opening.
API 609 BV-10 Butterfly Valve Usage Areas
The API 609 BV-10 Butterfly Valve offers a wide range of applications. It is widely used in the following industries and systems:
Heating, Ventilation and Air Conditioning Systems (HVAC): Contributes to energy savings by providing high efficiency and sealing.
Water Treatment and Distribution Systems: Provides reliable performance in clean and wastewater systems.
Mining Industry: Provides durability in harsh working conditions.
Shipbuilding and Drilling Facilities: Provides long-lasting use by offering high resistance to sea water.
Sugar Industry, Food and Chemical Enterprises: Can be used hygienically and safely.
Fire Extinguishing Systems: Provides fire safety with a fast and reliable closing mechanism.
Water, Seawater, Dust, Gas, Wastewater and Air Applications: Offers reliable performance in a wide range of applications.
Installation and Usage Recommendations
During installation of the API 609 BV-10 Butterfly Valve, the valve's clapper must be checked for free movement. The valve stem can be installed horizontally or vertically, but horizontal installation is preferred for sizes DN300 and above. This ensures the valve's most efficient operation and ensures long service life.
