Check valves TFW silent, ball, etc.

Double-leaf check valves

The double-leaf flanged check valve TFW will be used in complex engineering systems to prevent the consequences of hydraulic shocks, for example, when the pump is turned off. The shut-off element of the valve is made in the form of a disk, which is folded in half under the influence of the flow of the medium, and when exposed to the reverse flow, the disk returns to its original position, thereby blocking its further movement in the pipeline system.

Models: with two plates, with one plate; with double pump; made of cast iron, carbon steel and stainless steel.

Rotary check valves

Rotary check valves TFW for industrial purposes are used for pumping a variety of media, industrial water purification, pumping stations and other complex equipment. The devices are usually mounted in conjunction with shut-off valves and perform the function of preventing the reverse flow of media, for example, at the outlet of a hydraulic pump, where a wedge valve and a check valve are installed together.

Models: BS5153, ANSI B16; made of cast iron.

Silent check valves

Silent check valves TFW are designed to prevent hydraulic shock by forcibly closing before flow reversal can occur. The valve closes silently, is reliable and does not require regular maintenance. Silent check valves are commonly used in vertical turbine pumping units when pumping from a well to an elevated reservoir.

Models: DN40-300; made of cast iron/ductile iron.

Ball Check valves

Ball check valves TFW are a type of pipeline fittings that provide a one–way flow of working media in various engineering systems. Due to its special design, such a valve passes the medium in one direction and prevents its reverse movement. This principle of operation makes it possible to secure systems operating under pressure.

Models: DN40-250; made of cast iron.
