Specification of Brass-Plated DN200 Dual Duo Wafer Type Check Non Return Valve 316ss Swing DN25 DN80 6″ DN150mm

This brass-plated DN200 Dual Duo Wafer Kind Examine Valve stops opposite flow. It avoids backflow in pipelines. Made from 316 stainless steel, it stands up to deterioration well. The brass plating adds additional protection. It offers a good surface as well.

This valve uses a wafer design. Setup is very easy. It fits in between standard pipeline flanges. Bolts hold it firmly. This saves space compared to other valves. The double duo swing disc design is key. 2 pivoted discs open with forward circulation. They close swiftly when circulation stops or reverses. This double disc arrangement makes sealing really dependable. Leakage danger is low. The shutoff requires little upkeep. It runs instantly. Flow pressure opens up the discs. Gravity and back pressure close them. No external source of power is needed.

The shutoff works for many pipeline dimensions. Usual dimensions include DN25 (1 inch), DN80 (3 inch), DN150 (6 inch), and DN200 (8 inch). It fits basic pipes conveniently. Its small wafer body is a big plus. This shutoff is solid. It takes care of moderate stress well. It is built for water supply, home heating, air flow, air conditioning (HEATING AND COOLING), and industrial usages. It works well with water, air, vapor, and other suitable liquids. Avoid very harsh chemicals.

This shutoff provides good worth. Its straightforward style means reduced price. It lasts a very long time. The 316SS material and brass plating fight corrosion. The twin discs make sure dependable backflow avoidance. This shutoff protects pumps and tools. It maintains systems running smoothly. It is a practical choice for flow control.

Applications of Brass-Plated DN200 Dual Duo Wafer Type Check Non Return Valve 316ss Swing DN25 DN80 6″ DN150mm

This brass-plated check shutoff quits opposite flow. It utilizes a swing mechanism within. The disc swings open with ahead flow. The disc swings closed if flow tries to turn around. This safeguards pumps and equipment. It protects against contamination. It prevents water hammer issues.

The shutoff body utilizes difficult 316 stainless-steel. Brass plating covers the outdoors. This provides excellent deterioration resistance. The brass surface likewise looks attractive. It matches visible installations. The inner components stay durable. 316SS deals with several fluids well.

This is a wafer-style valve. It fits securely between pipeline flanges. You bolt it in place. This design conserves room. It is much lighter than flanged valves. Installation is simpler. It benefits numerous pipe dimensions. Alternatives consist of DN25, DN80, DN150 (6″), and DN200.

These shutoffs are common in water systems. They stop backflow in pump discharge lines. They protect boilers in heater. They work in commercial process piping. They manage water, air, oil, and mild chemicals. They are trusted for one-way flow control.

The swing disc layout reduces pressure decline. Flow relocations freely forward. The disc closes quick when flow stops. This makes certain a tight seal. The brass plating secures the outside. The 316SS internals stand up to wear. This combination offers long life span.

You locate these shutoffs in industrial buildings. They operate in manufacturing facilities. They are made use of in water therapy plants. They appropriate for HVAC systems. They perform well in watering arrangements. They are a practical selection for several applications requiring backflow prevention.
