ZDLSY type electric steam trap is according to the thermal power plant equipment steam drain and professional development design and production of a new generation of steam trap, the product has small volume, light weight, large capacity of valve, switch, valve core and valve seat with hartz alloy welding, close no inner leakage, anti high pressure resistance, but also in the inflammable and explosive occasions to use, according to the control system, or adjust the signal of instrument, cut off or open the valve, so as to realize the use of accused parameters requirements. So it is widely applied in coal-fired power plants and other industries of the remote control. This type of product by the positive action and reaction, their level of nominal diameter dn (mm) of 20 ~ 100 mm; Nominal pressure level pn by 150 lb (2.0 mpa), 300 lb (5.0 mpa), 600 lb (mpa) 10, 900 lb (15 mpa) such as multiple hierarchical; Signal within 4 ~ 20 (ma); Almost approximate to zero leakage, leakage of the product has a variety of specifications to choose from.

* actuators have open, electrical closed two forms: when the input signal increases, the valve in the closed position gradually turned to open position for electricity open, when the input signal increases, the valve gradually shift from the open position to the closed position for the electric type.

Department of titanium alloy, surfacing valve core seat is suitable for high temperature and cryogenic and other harsh working conditions.
