Check Valves Models

Check Valves

This is a non-return type valve for preventing back flow. Upon request, the manual closing speed option can be obtained through dash-pot.

It can be manufactured from special material according to NACE corrosion standards and/or temperature class.

Swing Check Valves

Swing check valves are produced within a wide range of sizes, which allows the flow from one direction. They have an obturator, which automatically blocks the flowing in one direction. Flow direction is marked on the body, for correct assembly. The vertical and horizontal mounting is possible through the line.
It is a full bore valve, suitable for the pig transition. It is used as line valve in natural gas and crude oil pipelines and also used in Pig Stations, Compressor & Metering Stations, Regulating & Metering Stations, Pumping and Filling Stations.
Special sizes are available as tailor made.

E400

Dual Disc Check Valves

This model is a Dual Disc Compact Valve. Wafer type is preferred, which can be mounted between two flanges. Upon request Lug Type and Double Flange types are available. It keeps the flow rate loss at the lowest level, in the processes. This design prevents shocks and strikes.
At pump start-up flowing fluid enters the valve from the seat end and forces the two disc to open fully, until they strike touch-on disc stop pin. When there is a counter flow or in pump shut-down cases, valve closes rapidly with help of the torsion springs.
It can be used instead of ’tilting disc’ check valve. When compared with other check valves, it outstands with the ability to work in any connections, vertical-opposite, horizontal or inclined. Pigging is not applicable.

E40D

Nozzle Check Valves

This type of check valve can operate without an impact by absorbing shock and vibrations.The flow is provided in laminar state. It is possible to have the required flow rate by adjusting the flow orifice. Pigging is not applicable.
