What is a Tilting Disc Check Valve?

Tilting disc check valve is a types of check valve used in plumbing systems to stop reverse flow. They are made out of a disc that closes to stop backflow and swings or tilts away from the valve seat to let flow in one direction. The term “titling” may refer to the tilting action of the disc as it moves in response to fluid flow. These valves are frequently found in settings like water supply systems, wastewater treatment facilities, and other industrial processes where backflow protection is important.


Key Components:

The key components of a tilting disc check valve typically include:

  1. The main housing of the valve known as the body contains all the internal components and provides the connection points for the piping system.
  2. The movable component of the valve known as the Disc that tilts or pivots to allow forward flow and prevent backflow. The disc can be flat or slightly concave and is attached to a hinge mechanism within the valve body.
  3. The mechanism that allows the disc to tilt or pivot is called the Hinge Mechanism. It can be a pin, shaft, or other type of hinge arrangement that enables the disc to move freely in response to fluid flow.
  4. The sealing surface against which the disc rests when the valve is closed is the seat. It ensures a tight seal to prevent backflow when the disc is in the closed position.
  5. In some designs, a spring may be incorporated to assist in closing the disc and provide additional sealing force.
  6. In some designs, especially in larger valves or those used in high-pressure systems, a cover or bonnet may be present to provide protection and access to the internal components for maintenance or repair.

Swing check valve v/s Tilting disc check valve:

Swing check valves and titling disc check valves are both types of check valves, but they operate differently.

Swing Check Valve:

In a swing check valve, a hinged  shaped disc swings open to allow forward flow and swings closed to prevent backflow. The disc is typically mounted on a hinge or a pin at the top of the valve body. When there is forward flow, the force of the fluid pushes the disc open, allowing flow through the valve. When flow stops or reverses, gravity or backflow pressure causes the disc to swing shut, preventing reverse flow.

Titling Disc Check Valve:

In a titling disc check valve, the disc tilts or pivots on a hinge as fluid flows through the valve. The disc remains partially open during forward flow, allowing fluid to pass through. When flow stops or reverses, the disc tilts back into a closed position, blocking reverse flow. Titling disc check valves typically have a lower pressure drop compared to swing check valves, making them suitable for applications with low headroom or low-pressure systems.

While both types of valves serve the same purpose of preventing backflow, the choice between them depends various factor. For correct choice you must choose a reliable manufacturer like Valvesonly Europe your trusted tilting disc valve manufacturer in Europe.
