Versatile Material Construction

The DCVs body is available in stainless steel, carbon steel, or cast iron, with stainless steel discs, ensuring excellent durability and compatibility with various industrial media. This flexibility enables the valve to cater to demanding applications while providing corrosion resistance and longevity.

Reliable Backflow Prevention

With its wafer-type, dual plate (spring loaded) structure, the Disc Check Valve effectively blocks fluid reversal, safeguarding equipment and maintaining system integrity. Its efficient design enables quick installation between flanges and supports pressures up to PN25.

Wide Application Range

Engineered for water, steam, oil, and gas flow, the DCV is adaptable to a range of industrial pipelines, making it a preferred choice for distributors, manufacturers, and suppliers. Its operating range (DN40 to DN300, up to 200C) ensures performance across diverse conditions.

FAQs of Disc Check Valve (DCV):

Q: How does the Disc Check Valve (DCV) prevent backflow in industrial pipelines?

A: The DCV utilizes a spring-loaded, dual plate (disc) mechanism within a wafer-type body to close automatically when flow reverses, ensuring media only flows in the intended direction and preventing backflow that could damage equipment or disrupt system efficiency.

Q: What materials are used for the body and disc of this check valve?

A: The valve body is available in stainless steel, carbon steel, or cast iron, while the disc is crafted from stainless steel. This combination provides strength, longevity, and corrosion resistance suitable for challenging industrial applications.

Q: Where can Disc Check Valves be installed and what media are they suitable for?

A: DCVs are intended for installation in industrial pipeline systems handling water, steam, oil, and gas. Their robust design and material compatibility make them suitable across various industries, including those requiring resistance to high temperature and pressure.

Q: What is the process for installing a wafer-type Disc Check Valve?

A: Installation is straightforward: the valve is simply mounted between two pipeline flanges using standard gaskets and bolts. The wafer flange end simplifies alignment, and no additional spacers or supports are typically required.

Q: When should a Disc Check Valve be considered for a pipeline system?

A: A DCV should be used whenever there is a need to prevent backflow in pressurized flow systems, especially in hot or hazardous media like steam, oil, or gas, and when compact installation between flanges is desired.

Q: What benefits does a dual plate, spring-loaded check valve offer over other types?

A: Dual plate, spring-loaded DCVs provide rapid and reliable closure, minimizing water hammer and ensuring system protection. Their compact wafer design reduces weight and installation space compared to traditional swing check valves.
