Lift Valve TRIZ Cases
- Powder-Metallurgical Composition for Wear-Resistant Sliding Parts
A multi-phase iron-base powder with molybdenum-rich hard phases improves wear resistance and heat conductivity in sintered sliding parts.
- Eccentric Butterfly Valve Groove Geometry for Lower Pressure Loss
Curved groove surfaces in the valve member expand opening area while suppressing vortices and pressure loss in an eccentric butterfly valve.
- Fluoroplastic Butterfly Valve Sealing Structure for Low Torque
Unequal-width sealing surfaces and a back-up ring help a fluoroplastic butterfly valve resist heat and pressure while lowering torque and wear.
- S-Shaped Butterfly Valve Seat for High-Pressure Sealing Wear
An S-shaped composite valve seat and shaped retainer improve bidirectional sealing under pressure while reducing wear, creep, and valve body stress.
- Butterfly Valve Seat Ring Structure for Sealability and Easy Assembly
Arcuate outer projections keep the butterfly valve seat ring stable during assembly and operation while preserving uniform compression and sealing.
- Butterfly Valve Free-Form Sealing Surface for Lower Actuation Torque
A free-form asymmetric sealing surface lets the seal separate uniformly, cutting friction and lowering butterfly valve actuation torque.
- Centric Butterfly Valve Seal Using Fluid Pressure for Low-Wear Sealing
A free-moving seal uses fluid pressure to improve centric butterfly valve sealing while reducing torque, wear, and seal stress.
- Fivefold Asymmetric Butterfly Valve Sealing for Low Wear Torque
A fivefold asymmetric sealing surface lets the seal break contact at minimal rotation, cutting shaft-area wear, friction, and actuation torque.
- Butterfly Valve Sensor Module for Wireless Condition Monitoring
A locking-screw sensor module adds wireless access to valve position, pressure, and temperature data for earlier leak and seal-wear detection.
- Twin-Disc Butterfly Valve Sealing for Compact DIB/DBB Isolation
A sloped annular seal lets twin butterfly discs shut off uni- or bi-directional flow in a smaller DIB/DBB valve assembly.
