SlantTech
Slanted Seat Check Valve Double Offset, Heavy Duty Design. Highly Efficient, Rubber-to-metal sealing or Metal-to-metal sealing
The SlantTech is the result of AVM’s expertise in cutting edge valve technology, starting more than 5 decades ago.
AVM SlantTech Slanted Seat Check Valve was Designed for the water industry, taking into Account the latest development and know-how.
General advantages of Tilting Disc Check Valves:
- Functional light design:
a – Cost effective in purchase: Light and compact design results in a comparatively good price against other valve types
b – Cost effective during installation: Light design allows easy handling and installation
c – Cost effective in use: Problem free designs
d – Cost effective in maintenance: The design is almost maintenance free. Replacement of the resilient seal (disc edge) is the only major part to be changed out. - Smaller requirement for installation space
- Field approved safe design
- Low head-loss
- Can used for several types of applications
Easily replaceable O-ring shaft seals
Specific advantages of AVM SlantTech:
- The best combination for a check valve is
a – High eccentricity
b – Short stroke
This is achieved with this design - Optimum closing of rubber seat into the body seat
- Shear strain of the rubber seat much reduced due to the high eccentricity
- Sealing ring completely relieved from stress and wear in the open position
- The rubber seal is uninterrupted by shaft bearings etc
- The seal is easily replaced when the valve disc is open
- Replacement of the rubber seal is very economical and be done without dismantling of the valve
- The valve can be designed for higher working pressures, such as PN25 and PN40
- No risk for disc flutter (vibrations) by means of an unbalanced disc load
- Dashpot damper (bottom-mounted) is possible
Size Range and Pressure:
DN150 to DN3000 as standard
PN6 to PN40 as standard
