SOD203 Top Directed Double Seat Regulating Valve

SOD203 Top Directed Double Seat Regulating Valve

SQD203 electronic double-seat regulating valve adopts cool guiding structure, the valve body structure is tight and light, the fluid passage is $streamlined, the pressure drop loss is small, the circulation volume is large, the adjustable range is solid and wide, and the flow characteristic precision is high. Since the top and bottom of the valve core guide are fixed and have the characteristics of anti-vibration and wear resistance, the regulating valve is equipped with a small, hard-core and high-precision actuator that receives ON-OFF or 4~20mADC or 1~5V DC signals for proportional action, it is more suitable for good control under the process conditions requiring good dynamic stability, high reliability, high pressure, high pressure difference and easy plugging of slurry in fluid medium.

SOD203

Top-guided double-seat regulating valve

Electric Linear Stroke Regulating Valve

Product overview

SQD203 type electronic two-seat regulating valve adopts cool guiding structure, the valve body structure is tight and light, the fluid channel is S-streamlined, the pressure drop loss is small, the circulation volume is large, the adjustable range is solid and wide, and the flow characteristic precision is high. Since the top and bottom of the valve core guide are fixed and have the characteristics of anti-vibration and wear resistance, the regulating valve is equipped with a small, hard-core and high-precision actuator that receives ON-OFF or 4~20mADC or 1~5V DC signals for proportional action, it is more suitable for good control under the process conditions requiring good dynamic stability, high reliability, high pressure, high pressure difference and easy plugging of slurry in fluid medium.
