Опис
Product Overview
На Вентил за пеперутка на нафора од леано железо EPDM is a high-performance flow control device designed for reliable on/off and throttling service in water, воздухот, пареа, масло, and gas pipelines. Featuring a durable cast iron body with an EPDM rubber liner that fully encapsulates the disc sealing area, this valve provides bubble-tight shut-off and excellent corrosion resistance. The wafer-style body allows for compact installation between flanges, making it ideal for space-constrained piping systems. Available in sizes from DN50 to DN1000 and configurable with manual lever, worm gear, or electric/pneumatic actuators, this valve is suitable for a wide range of industrial, општински, и комерцијални апликации. With OEM/ODM customization support and a 1-year warranty, it is a cost-effective and reliable solution for flow control in water treatment, HVAC, chemical processing, and power generation.

FAQ
П1: What is the difference between EPDM soft sealing and PTFE hard sealing?
А: EPDM is a soft rubber seal that provides bubble-tight sealing and offers good resistance to water, пареа, and mild chemicals, with a temperature range of -20°C to +120°C. PTFE hard sealing offers superior chemical resistance and a wider temperature range (up to +230°C), though its sealing performance is slightly lower than that of EPDM. The choice depends on the medium type and operating temperature.
П2: What is the difference between wafer-style and lug-style butterfly valves?
А: Wafer-style butterfly valves are installed between two flanges using through-bolts; they are easy to install, лесен, и рентабилно, making them suitable for general applications. Lug-style butterfly valves feature threaded lugs on both sides, allowing them to be bolted individually to flanges; this enables the downstream piping to be disconnected without draining the system, facilitating maintenance.
П3: Can this butterfly valve be used for steam?
А: Да. Butterfly valves with EPDM seals are suitable for saturated steam (up to +120°C). For higher-temperature steam applications, we recommend selecting a configuration with PTFE or metal seals. Please specify the steam operating conditions when placing your order.
П4: Can the valve body material be upgraded to ductile iron or stainless steel?
А: Да. We offer options to upgrade the valve body material to ductile iron (for higher strength and impact toughness) or stainless steel (for superior corrosion resistance). Please specify your requirements when placing your order.
