Cast iron flanged butterfly valves with stainless steel disc and EPDM sealing PN 16 are devices used for regulating or completely shutting off the flow of working medium in pipelines. They feature simple design and operational efficiency, making them popular in various industries.
Construction of Electric Or Pneumatic Actuated Butterfly Valve
The butterfly valve consists of several key components: body, disc (or plate), actuator, and seal. The body is made of cast iron, providing high strength and corrosion resistance. The stainless steel disc ensures durability and reliability when operating in various conditions, including aggressive environments.
Stainless Steel Disc (CF8)
The stainless steel disc is the main component of the valve responsible for flow shut-off. A circular disc shape is used to ensure even pressure distribution across the entire surface. CF8 stainless steel provides high corrosion resistance and strength. It is used in food processing equipment and water supply systems due to its ability to resist corrosion and maintain hygienic properties.
EPDM Sealing
EPDM (ethylene propylene diene monomer) is a synthetic rubber widely used as sealing material due to its excellent resistance to water, steam and many chemicals. EPDM seals provide reliable sealing between the disc and valve body, preventing leaks.
Connection Type
The flanged connection allows installation of butterfly valves between flat flanges without additional gaskets thanks to the EPDM seal.
Electric Actuator
Electric actuators are used to automate butterfly valve operation. They enable remote or automatic control of valve opening/closing depending on system operating conditions.
Advantages of Using Electric Actuators
- Automation: Actuators allow valve integration into automated control systems.
- Precision: Provide accurate valve position control.
- Safety: Reduce need for manual intervention in potentially hazardous conditions.
Applications
Butterfly valves with cast iron discs and EPDM seals are widely used in various industries:
- Water supply
- Wastewater drainage
- Oil and gas industry
- Chemical industry
