Product Overview
The EPDM Soft-Seal Cast Aron Wafer Butterfly Valve is a high-performance flow control device designed for reliable on/off and throttling service in water, moea, steam, oli, 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, mmasepala, le likopo tsa khoebo. 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
Q1: What is the difference between EPDM soft sealing and PTFE hard sealing?
A: EPDM is a soft rubber seal that provides bubble-tight sealing and offers good resistance to water, steam, le lik'hemik'hale tse bobebe, 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.
Q2: What is the difference between wafer-style and lug-style butterfly valves?
A: Wafer-style butterfly valves are installed between two flanges using through-bolts; ba bonolo ho kenya, e bobebe, le ho boloka chelete, 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.
Q3: Can this butterfly valve be used for steam?
A: Ee. 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.
Q4: Can the valve body material be upgraded to ductile iron or stainless steel?
A: Ee. We offer options to upgrade the valve body material to ductile iron (for higher strength and impact toughness) kapa tshepe e sa hlwekang (for superior corrosion resistance). Please specify your requirements when placing your order.
