Product information
Cast Steel Electric Actuator Globe Control Valve
Overview:
This product consists of 3810L series electronic electric actuator and a small single-seat ( sleeve ) regulating valve. The actuator has an integrated structure with built-in electronic controller modules, eliminating the need for additional servo amplifiers . It has high precision and is easy to install The characteristics of the sleeve valve are as follows:
- Adopting balanced valve core, the unbalanced force is small, the pressure difference is allowed to be large, and the operation is stable
- The large guide surface of the spool improves the oscillation caused by eddy currents and shocks and reduces damage
- The noise of the ordinary single and double seat valve regulating valve is reduced by about 10dB
- Simple structure, convenient assembly, and disassembly
