Cast iron wafer-style butterfly valves with zinc-plated cast iron disc PN 16 and EPDM sealing are devices used for regulating or completely shutting off the flow of working media 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 sealing. The body is made of cast iron, providing high strength and corrosion resistance. Cast iron disc offers excellent mechanical properties and can withstand significant loads.
Cast Iron Disc
The cast iron disc is the main valve element responsible for flow shut-off. A circular disc shape is used to ensure even pressure distribution across the entire surface. Cast iron as a material provides high compressive strength and good corrosion resistance when properly treated.
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
Wafer connection allows installing butterfly valves between flat flanges without the need for additional gaskets due to the EPDM sealing.
Electric Actuator
Electric actuators are used to automate butterfly valve operation. They allow remote or automatic control of valve opening and closing depending on system operating conditions.
Advantages of Electric Actuators
- Automation: Electric actuators enable 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
