Plug Valves TRIZ Cases

Double-seat valve prevents direct pressurization of the seat area via pre-lift phases and tangential flow paths.

Segmented RF-controlled valve shuts off polybutylene piping flow to prevent oxidation leaks while maintaining sprinkler pressure.

An axial locking slide plate secures insulated valves without disturbing thermal layers.

A dual seat ball valve design equalizes pressure between sealing surfaces to reduce contact forces and prevent deformation.

An elliptical valve seat with a hemispherically contoured sealing face creates a fluid-tight seal around the spherical ball member.

A conically widening outlet bore ensures complete drainage of liquid samples through unstable adhesion and gravity.

A trunnion ball valve packing uses a pressing mechanism to increase seal surface pressure at the tip outer peripheral region.

Local radius variations on the plug and house create a tight seal, eliminating costly silicone coatings and reducing operational effort for fluid drainage.

Segmenting the valve into a fixed housing and removable cartridge allows rapid maintenance while keeping the pipeline connected.

Segmented bridging elements alter internal fluid resistance to establish linearity between rotation angle and flow rate, eliminating non-linear control errors.

Porous lattice cores in additive manufactured ball valves cut weight by half without sacrificing strength, easing transport and assembly.

A mix-proof double seat valve uses a hollow rod design to create a self-draining leakage cavity for leak-free switching.

An integrated check valve within a disposable dental valve prevents backflow and cross-contamination, eliminating the need for separate sterilization cycles.

Segmenting stop contours onto a separate control housing eliminates tight tolerance coordination between housings, simplifying manufacturing.

Closed liquid medium actuation reduces sanitary valve size while preventing contamination risks.
