SOD103 Top Directed Double Seat Regulating Valve

SOD103 Top Directed Double Seat Regulating Valve

SQD103 top-guided double-seat regulating valve adopts double-guided 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 wide, and the flow characteristic accuracy is high. Due to the guidance at the top and bottom of the spool, it has the characteristics of anti-micro wear resistance. The regulating valve is equipped with a multi-spring film actuator, which has a small structure and a large output force. It is more suitable for good stability, high reliability, high pressure, high pressure difference and good control under the process conditions where the slurry is easy to block in the fluid medium.

Valve function (core formal)

Air-off FO (with positive action actuator)
When the air supply fails, the actuator spring will open the valve.
Air-open FC (with reaction actuator)
When the air supply fails, the actuator spring closes the valve.

Accessories (configured as required)

Positioner, air filter pressure reducing valve, handwheel mechanism, limit switch, solenoid valve, valve position transmitter, relay, position retaining valve, others
