Product Description

Product Description
D373h Stainless Steel Hard Sealing Wafer Butterfly Valve
The D373H Hard Sealing Wafer Butterfly Valve is a reliable, durable valve designed for precise flow control in a variety of industrial applications. Its hard-sealing mechanism ensures long-lasting performance with minimal leakage, making it ideal for use in systems where high sealing integrity is required.
Constructed from cast steel (WCB), stainless steel (CF8/CF8M), or carbon steel, the valve is built to withstand demanding conditions, including high-pressure and temperature environments. The wafer design enables the valve to be installed between flanges, making it suitable for both new installations and replacements.
The D373H is widely used in HVAC systems, petrochemical, power generation, and water treatment plants, handling a variety of fluids, including water, oil, gas, and chemicals. With its wide range of sizes (DN50 to DN600), this valve can meet the needs of both small and large systems.
The valve can be operated manually or automated with electric or pneumatic actuators, making it a versatile choice for various control applications. Its high sealing performance, combined with easy installation and maintenance, ensures that the D373H Hard Sealing Wafer Butterfly Valve is a long-lasting solution for any industrial fluid control system.
