ZDSG type straight stroke electric control valve has the advantages of simple structure, small resistance, circulation flow path than with other large caliber valve, no leakage, can be used to adjust the high viscosity fluid and suspended particles, according to different membrane materials (rubber or PTFE) suitable for regulating alkali, strong corrosive medium. The diaphragm valve equipped with PSL series electric actuator. The electric actuator in the servo system, no additional servo amplifiers, have the input control signal (4-20MA or 1-5VDC) and single-phase power can control the operation, we can adjust the parameters of pressure, flow, temperature, liquid level etc..
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
Actuator: PSL intelligent direct stroke actuator, 3810 electric actuator, detailed information, please refer to the corresponding implementation
