soupapes à pincement et vannes de tuyau
Une fois complètement ouverte, une vanne à pincement offre un passage libre et sans restriction, réduisant ainsi les risques d'obstruction, d'accumulation de matières et d'usure excessive. Son fonctionnement repose sur la compression mécanique ou pneumatique de la gaine en caoutchouc, ce qui permet son utilisation pour l'arrêt et la régulation de débit.
De nombreuses vannes à pincement industrielles sont conçues avec un manchon en caoutchouc remplaçable, permettant ainsi de changer la principale pièce d'usure sans remplacer la vanne entière. Cette solution offre une solution durable et économique pour les applications exigeantes dans des secteurs tels que l'exploitation minière, le traitement des minéraux, le traitement de l'eau, la chimie et autres procédés de manipulation de fluides chargés.
Lined Knife Gate Valve
Our Lined Knife Gate Valves are designed for reliable on/off isolation in abrasive and corrosive process applications. The valve body and chest are fully lined with moulded rubber, protecting the metal components from direct contact with the process media.
The flush-bottom, full round port design eliminates cavities where solids can collect and provides zero discharge to atmosphere, making the valve well suited for slurry and other demanding media.
Wafer Knife Gate Valve
Our Wafer Knife Gate Valves provide a compact solution for slurry and abrasive media applications where installation space is limited. The full port design allows the gate to be fully isolated by the sleeves in the open position.
When closed, the gate moves between the sleeves to provide a bi-directional bubble-tight seal with zero downstream leakage. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
Flanged Knife Gate Valve
Heavy-duty rubber sleeves protect the valve from wear, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
High Pressure Slurry Knife Gate Valve
Heavy-duty rubber sleeves provide sealing and wear resistance, while the gate passes through the sleeves during closing. Solids are purged through the bottom of the valve housing, helping prevent clogging and gate jamming.
Severe Service Lined Knife Gate Valve
The double-layer sealing system uses an inner seal to isolate the process flow and an outer seal to prevent leakage to atmosphere, providing extended service life and reliable containment in severe-duty applications.
Urethane Lined Knife Gate Valve
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.
Severe Service Wafer Sleeve Knife Gate Valve
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere, improving reliability and service life.
Lined Moulded Knife Gate Valve
The flush-bottom, full round port design eliminates pockets where solids can collect and provides zero discharge to atmosphere.
