Válvula de retenção de disco inclinado

A check valve is a valve that allows fluid to flow in one direction and prevents backflow. The structure can be divided into two major categories: one is a ball check valve, whose gate body is spherical and can be opened or closed automatically; the other is a disc check valve, whose gate body is a round disc shape that can prevent backflow according to the pressure of the fluid.

Válvula de retençãos can be made of a variety of materials, including brass, stainless steel, cast iron, plastic (PVC or CPVC), and other alloys, and are selected according to the application and fluid type.

Válvula de retençãos are commonly used in applications such as water and wastewater systems, oil and gas pipelines, chemical processing, and HVAC systems to prevent backflow and protect equipment.

A properly functioning check valve should allow fluid to flow in one direction without any noticeable resistance and completely prevent backflow. Signs of failure include reverse flow, unusual noise or vibration.

Válvula de retençãos should be installed in the direction of flow indicated on the valve body. Válvula de retençãos are usually installed in horizontal or vertical piping systems, depending on the specific type and purpose.
