Using WCB material, full consid-eration of corrosion allowance, minimum shell wall thickness, pressure and temperature rating.
The unique air exhaust valve makes the trap no air blocking phenomenon caused by air and other non-condensable gases during initial or normal opera-
Effectively prevent pipeline impurities from entering the valveKeeps traps working properly while preventing water hammer from damaging internal components
Defect-free laser-welded float ensures long service life of the trapStainless Steel Float
Unique flexible closing mechanism No rigid impact to ensure long life Micron-level high-precision valve seat. The valve core ensures reliable and tight
Precisely calculated structure of the floating ball assembly enables the closing system to work in a water-sealed state without steam leakage
The lever ball float trap has the charac-teristics of large displacement, long life, good energy saving effect, water hammer resistance, beautiful appearance, etc. It is widely used in process heat tracing, jacketed heating kettles tank, reboilers
The technical advantages of VMV traps are: unique and reasonable structure , high-precision internal parts.
The flexible closing system is applied to the lever ball float trap, which solves the problems of short life and lax closing. In the design, the strength of the shell, the pressure and temperature grade, the manufacturability of casting, the impact caused by the fluid flow channel and the water-vapor mixing are considered, and the closed system works in a water-sealed state.
Lever ball float steam trap works on the difference in density between steam and condensate. When the valve body is filled with condensed water and non-condensable gas, the air exhaust valve is opened to remove the non-condensable gas,the floating ball moves up to drive the valve core to open, and after the condensate is drained, the floating ball drives the valve core to move down and closes the trap.
The biggest advantage of lever ball float trap is high back pressure rate (differential pressure 0.0lbar can work), long life, reliable action, easy maintenance and no original steam
The lever ball float type steam trap is made of ASTM216 WCB/WC6/CF8/ CF8M stainless steel, some bonnets are made of ASTM A105/F304/F316,the inner parts are made of stainless steel, and there is a built-in filter device.

The lever ball float type steam trap is for continuous
drainage, the subcooling degree is about 5℃, and the
back pressure rate is over 95% (back-end pipeline
pressure/steam pressure). In general, the safety factor
is 2-3 times when selecting, and 5-8 times for air
separation units and drying cylinders. Condensate volume and differential pressure of steam-using equipment are
important indicators for model selection. The same type
of trap increases with the increase of pressure differ-
ence and displacement. See the details on displacement
curve.
Special reminder: Please do not mistakenly think that a
trap with a large diameter has a large displacement.
The lever ball float trap is installed horizontally at
the bottom of the pipeline or equipment, and the SFT10
trap can be installed horizontally or vertically. The
basic configuration is shown in the figure on the right.
Lever ball float traps are best suited for back pressure recovery of condensate.
