Description:

  Knife gate valve (knife gate) is a type of gate valve in which the locking element is made in the form of a flat knife (gate). The main mechanism of the gate valve is a knife, which is a steel plate with a stem. The locking mechanism moves along the guides between the two flanges and interrupts the flow.

Conventional wedge gate valves are designed with places where residues of the working medium can accumulate, the so-called "stagnant zones". Solid particles collected there can interfere with its normal operation. Knife gate valves (knife gate valves), due to their design, do not have this drawback: they have a knife that, when opened, goes out, and when closed, it cuts solid particles of the working medium with a sharp edge, which ensures tightness.

Knife gate valve (knife gate valve) ABRA-KV-01 is a special fitting used in rather harsh and harsh conditions. Knife gate valves (knife gate) ABRA-KV-01 are used for complete closing or opening of the medium flow, i.e. are shut-off valves.

Such a gate valve has a double-sided tightness. Gate valve ABRA-KV-01 is controlled by a handwheel with a non-rising stem

Gate valves undergo double quality control - after hydrotesting, they are additionally tested with air.
