所屬類別：Special fluorine regulating valve

ZDLT electric diaphragm valve by the PS and 3610 series of straight travel electric actuator and valve. Electric actuator for the electronic integrated structure, a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to adjust to working parameters of pressure, flow, liquid level, temperature etc.. Is sensitive, simple connection, big flow, small volume, high accuracy regulation. The control precision and has better performance than DKZ.
Diaphragm valve body flow smoothly, a throttling element for the elastic diaphragm, valve without stuffing box cover. The valve flow capacity than the general valve and no leakage, the allowable pressure shut-off valve can be used within the scope of. Condition of the valve is suitable for high viscous fluid, suspended particles, fiber media and toxic, corrosive medium.
