Manual Valves
On a human scale—millimeter precision, century-grade reliability.
Next-Level: Precision You Can See, Lifespan You Can Count.
- 0.1 mm travel, visualized—mechanical memory pointer + laser scale, read at a glance.
- Zero power, zero electronics—stays rock-solid on day one, even during blackouts, blizzards, or explosive atmospheres.
- 100-year design life—nitrided stem + Stellite seat, no re-grinding for life.
Manual Valves Series
Ball Valves
A 90° lever swing spins the sphere for instant bubble-tight shut-off and wear-free sealing in high-cycle, high-pressure pipelines.
Butterfly Valves
A simple hand-wheel turns the slim disc 90°, delivering rapid, low-torque isolation and accurate flow control in large-bore, space-tight systems.
Gate Valves
A few clockwise turns raise the solid wedge, creating full-bore, pressure-tight isolation with zero flow restriction for straight-pipe, low-loss duties.
Knife Gate Valves
One quick hand-wheel stroke drives the razor-edged blade, slicing through thick slurries and providing bi-directional, drop-tight shut-off in abrasive lines.
Globe Valves
Finger-tip wheel rotation advances the plug along the guided stem, granting linear throttling and Class VI shut-off under high-ΔP, high-temperature process loops.
Check Valves
Flow itself lifts the gravity-assisted disc, opening wide for minimum loss and snapping back to prevent water-hammer and back-flow—no hand action required.
