Concentric Soft Seal Wafer Butterfly Valve | Cast Iron Body with EPDM Seat | Zero Offset Butterfly Valve for Industrial Flow Control DN50-DN1000

Product Overview

The Concentric (Zero Offset) Soft Seal Wafer Butterfly Valve is a reliable and cost-effective flow control solution designed for water, ОВК, industrial and general pipeline applications.

Featuring a zero offset concentric design, the valve stem is positioned at the centerline of the disc and valve body, allowing uniform sealing contact between the disc and EPDM seat. This structure provides bubble-tight shut-off, low operating torque, и длительный срок службы.

The valve is manufactured with a durable cast iron body and EPDM soft seat, offering excellent corrosion resistance and reliable performance in water, воздух, пар, oil and other compatible media. The wafer-style compact design allows easy installation between flanges, making it ideal for piping systems where space and cost efficiency are important.

Available in sizes from DN50 to DN1000 (2″-40″), with manual lever, worm gear, electric or pneumatic actuator options, this concentric butterfly valve is widely used in water treatment plants, системы отопления, вентиляции и кондиционирования, системы противопожарной защиты, industrial process pipelines and power generation applications.

OEM and ODM customization are available according to customer requirements.

FAQ

1 квартал: What is a concentric (zero offset) butterfly valve?

А: A concentric butterfly valve, also called a zero offset butterfly valve, is designed with the shaft located at the centerline of the valve disc and body. The disc rotates through the soft seat with uniform contact, providing reliable sealing and simple operation.

2 квартал: What is the difference between concentric and double offset butterfly valves?

А: Concentric butterfly valves use a simple centerline design and are mainly used for water, HVAC and general industrial applications. Double offset butterfly valves reduce seat friction and are suitable for higher pressure and more demanding applications.

Q3: 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.

Q4: 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.
