ZDLP electric single-seat electric control valve, the PS series and 3610 series of straight-stroke electric actuator and low-flow resistance through the single-seat valve (also available with other brands straight stroke actuator). Electric actuator for the electronic integration structure, with a servo amplifier, the input control signal (4-20mADC or 1-5VDC) and the power to control the valve opening, to the pressure, flow, level, temperature and other parameters adjust. With sensitive action, simple connection, large flow, small size, high regulation accuracy. Control accuracy and performance than the DKZ type has significantly improved.

Single-seat valve for leakage on the strict requirements of the valve before and after the low pressure and a certain viscosity of the occasion. Widely used in electric power, metallurgy, chemical industry, petroleum, environmental protection, light industry, equipment and other industries.

Note: 
 1, the same grid on the row for the double-sealed type allows the pressure difference, the lower row is a single sealed type to allow pressure. 
 2, the actual configuration needs to be based on specific process parameters. If the pressure difference is not clear or the maximum working pressure is out of the range, please contact us and take appropriate measures to solve it.
