Specification of 1/2″-4″ DN15~DN100 Brass Non Return Valve Brass Check Valve Brass Swing Medium Temperature Hydraulic Check Valve

This brass non-return valve stops reverse flow in your piping system. It works for pipe sizes from 1/2 inch to 4 inches. That equals DN15 to DN100. The body uses durable brass. This gives good corrosion resistance. The internal mechanism is a swing disc. Fluid pressure opens the disc. Flow moves forward freely. Reverse flow pressure forces the disc shut. This blocks backflow effectively. It protects pumps and equipment.

The valve suits medium temperature applications. It handles liquids or gases up to 120 degrees Celsius. Common uses include water lines, heating systems, and compressed air. It works with oil or gas too. Standard pressure ratings are PN16 and PN25. Choose the rating matching your system pressure. Installation direction is critical. Install it horizontally for best performance. Vertical installation is possible. Ensure flow direction is upward. An arrow on the valve body shows the correct flow path.

Connection types are threaded. Common options are BSPP (parallel) or BSPT (tapered) threads. Confirm the thread type needed for your pipes. The brass body ensures long service life. It resists rust and common water corrosion. The swing disc design minimizes pressure drop. Forward flow encounters little resistance. Maintenance is simple. Usually, no regular upkeep is needed. The valve just works reliably. It provides essential protection against backflow damage. Select the correct size and pressure rating for your specific job. This ensures proper function and system safety.

Applications of 1/2″-4″ DN15~DN100 Brass Non Return Valve Brass Check Valve Brass Swing Medium Temperature Hydraulic Check Valve

This brass check valve stops water or fluid from flowing backward. It fits pipe sizes 1/2 inch up to 4 inches. That is DN15 to DN100. The valve body is brass. Brass resists rust. It handles medium heat levels well. This valve works in water systems. It works in oil systems. It works with air too.

Use it behind water pumps. It stops water hammer. Water hammer damages pipes. It protects the pump. Install it on hot water heaters. It keeps hot water inside the tank. Cold water won’t flow back. Put it on boiler feed lines. Boilers need constant water flow. The valve ensures one direction only.

Factories need these valves. They connect to hydraulic power units. Hydraulic fluid must flow one way. Backflow ruins pumps. Use it on compressed air lines. Air pressure drops cause problems. The valve prevents air loss. It helps maintain system pressure.

Plumbers use these valves daily. They fit home water lines. They fit commercial buildings too. The swing disc design works simply. Flow pushes the disc open. Reverse flow slams it shut. This action is automatic. No electricity is needed. Installation is straightforward. Follow the flow arrow direction. Mount it horizontally or vertically.

The brass construction is durable. It handles pressure well. It handles temperature changes. Expect it to last for years. Maintenance is low. Just check for debris sometimes. Debris can block the disc. This valve is reliable protection. It safeguards your equipment. It prevents messy leaks. It avoids costly downtime. You get peace of mind.

5 FAQs of 1/2″-4″ DN15~DN100 Brass Non Return Valve Brass Check Valve Brass Swing Medium Temperature Hydraulic Check Valve

Here are 5 common questions about our 1/2″-4″ (DN15~DN100) Brass Non-Return Valve (Brass Check Valve, Brass Swing Check Valve) for medium temperature hydraulic systems:

What’s the flow direction? Install it correctly?
Install the valve so flow moves in the arrow direction marked on the valve body. Flow enters the inlet side. Flow pushes the internal disc open. Reverse flow automatically shuts the valve. Proper direction prevents leaks and damage.

What pressure can it handle?
These brass valves manage medium pressure levels common in hydraulic lines. Check the exact pressure rating stamped on the valve body. Never exceed the maximum pressure rating. Using it above the rated pressure risks valve failure.

Does it need maintenance?
These valves work reliably without regular maintenance. Debris in the line can sometimes cause problems. If flow stops or the valve leaks, inspect it. Dirt might be blocking the disc. Clean the valve interior. Replace the valve if parts are damaged.

What temperatures work?
The brass body and internal parts handle medium temperature fluids well. Confirm the specific temperature rating listed for the valve model. Very high temperatures can damage seals or warp parts. Ensure your system’s operating temperature stays within the valve’s limits.

What fluids are compatible?
Brass valves work with water, oil, air, and many common hydraulic fluids. Avoid using them with salt water, seawater, or highly acidic/corrosive chemicals. Brass can corrode with these fluids. Check the valve specifications for fluid compatibility details. Use the wrong fluid and the valve will deteriorate.
