 Lever ball float steam trap is not subject to the greatest advantage of the pressure, temperature, condensate flow fluctuations, continuous drainage, water that row, the minimum undercooling is 0 ℃, can achieve the best efficiency of heating equipment; Lever ball float steam trap seat total in the level below, forming a water seal, no steam leakage; its minimum working pressure 0.01Mpa, the maximum back pressure ratio ≤ 85%; with internal exhaust, float lever steam trap with automatic drain valve, can automatically exclude non-condensing gas, very sensitive, high quality of work, long service life. The trap design for a balanced two-seat structure, a large displacement of small size can be achieved, especially for large heating equipment and heat resistance gas station equipment, drainage, heating equipment is a large choice of steam traps.
