ZDLSY electric drain valve

Product Description:
The zdlsy electric drain valve is a new generation of steam drain valve specially developed, designed and produced by our company based on steam drainage of thermal power plant equipment. This product has the characteristics of small volume, light weight, large valve capacity, sensitive opening and closing, and the valve core and seat are welded with Hastelloy alloy, which can close without internal leakage and resist high pressure difference. It can also be used in flammable and explosive situations. According to the signal of the control system or regulating instrument, the valve can be cut off or opened to meet the requirements of the controlled parameters. Therefore, it is widely used for remote control in industries such as thermal power plants. This type of product is divided into positive and negative effects, with a nominal diameter grade dn (mm) ranging from 20 to 100mm; The nominal pressure rating pn is divided into multiple levels such as 150lb (2.0mpa), 300lb (5.0mpa), 600lb (10 mpa), 900lb (15 mpa), etc; Signal range 4-20 (ma); The leakage rate is almost zero, and there are multiple specifications to choose from for this product.
*The actuator has two forms of action: electric opening and electric closing. When the input signal increases, the valve gradually shifts from the closed position to the open position, which is called electric opening. When the input signal increases, the valve gradually shifts from the open position to the closed position, which is called electric closing.
*The valve core/seat is welded with Si Ti Lei alloy, suitable for high temperature/deep cold and other harsh working conditions
