Inline Spring Loaded Check Valve with Backflow Prevention FIP Connections

This brass inline check valve is spring-loaded and prevents backflow. The valve has FIP connections and is designed for potable water systems. It is made of brass for corrosion resistance and has a maximum working pressure of 125 psi. The valve has a 3/4 inch female NPT connection and is ideal for irrigation systems, landscape lighting, and other applications that require backflow prevention.

Check the valve’s design:

A check valve allows fluid (gas or liquid) to flow in one direction but prevents it from flowing back in the opposite direction. Check valves are used to avoid the backflow of fluids into a system. There are many different check valves, but all share the same purpose: to allow fluid to flow in one direction and prevent it from flowing back in the opposite direction.

Spring check valve and swing check valve operation:

Spring and swing check valves are two different types of valves used to prevent the backflow of fluid in a piping system. The spring check valve is a type of valve that uses a spring to keep the valve closed until there is a pressure differential between the inlet and outlet of the valve. The swing check valve is a type of valve that uses a swinging arm to keep the valve closed until there is a pressure differential between the inlet and outlet of the valve.

Non-return check valve Applications:

A non-return check valve is designed to permit fluid flow in one direction and prevent fluid flow in the opposite direction. Its primary purpose is to prevent backflow, which could cause contamination or damage to the system. Non-return check valves are used in various applications, including water, HVAC, and fuel systems.

Specifications of brass check valve

A brass check valve is a type of valve that prevents the reverse flow of fluid in a piping system. The device has two ports, one in and one out, with a disc-shaped flap mounted in the center. When the fluid flows in the direction of the arrow on the valve, the flap is pushed aside, allowing it to flow through. If reversed, the pressure of the fluid against the flap will close it and prevent backflow. Brass check valves are available in both threaded and flanged end connections.

Brass check valve’s Conclusion

A brass check valve is a type of valve that allows fluid to flow in one direction and prevents it from flowing in the opposite direction. The valve is made from brass, making it strong and resistant to corrosion. It has a disk-type seat that closes off the flow of fluid when the pressure is released. This type of valve is often used in water, gas, and oil systems.

Frequently Asked Questions

Here are typical questions by customers asked with usual, please feel free contact us if any further confused.

Brass valves have many different types, such as ball valves, garden tap, check valve, strainer, angle valve, gate valve, foot valve, and drain valve. The radiator valve and thermostatic mixing valve are works for water temperature. All of these valves are work for water plumbing systems, plumbing repair, and installation. So have to let water shut-off and shut-on. Some heating systems are related to hot water and cold water mixing for temperature control and stability. Our intelligent valves are functional. There are applications in commercial, residential, and industrial areas.

Underfloor heating radiant pex manifolds are usual for residential water distribution in a household, and it's top-rated in the home building industry. Manifold plumbing systems control hot and cold water that feeds flexible PEX supply lines to individual fixtures. Then water temperature is warm and stable in each room. Meanwhile, the heating accessories-flow meter gauge will monitor water and temperature in each room.

The motorized ball valve works automatically open and closed; they work with 220v-230v AC and 24v DC; they are applications in the heating system, air conditioner,3D printer, and others. The solenoid valve is with similar features.
