Tubular check valve refers to rely on the flow of media itself and automatically open and close the valve flap, used to prevent media back to the valve, also known as check valve, check valve, counterflow valve, and back pressure valve. Check valve is an automatic valve, its main role is to prevent media backflow, to prevent the pump and drive motor reversal, and the release of container media.
GLH41H cross-flow check valve using a special seal structure, regardless of the level of pressure after the valve, the valve is closed tight, good sealing performance. To overcome the general check valve sealing performance at low back pressure shortcomings. Tubular check valve with floating disc structure, can automatically compensate for wear and tear caused by installation and use of the error, to ensure that the sealing surface close fit and improve the sealing performance.

GLH41W stainless steel tubular check valve performance and features:
1. Streamlined runner, the medium does not flow around, the valve flow resistance is small, save energy.
2. Using a special seal structure, regardless of the level of pressure after the valve, the valve is closed tight, good sealing performance. To overcome the general check valve sealing performance at low back pressure shortcomings.
3. Floating flap structure, can automatically compensate for wear and tear caused by installation and use of the error, to ensure that the sealing surface close fit and improve the sealing performance.
4. Opening and closing stroke is short, and can automatically reset no impact at a small flow rate, the valve can be fully open, close time is short.
5. The valve is not limited by the installation position, which can be installed horizontally, vertically and at any angle.
6. Valve has a standard series and short series of two structure length, the length of the short series structure is particularly suitable for the installation of smaller, compact structure of the device.
