DELCO Cast Steel Electric Actuator Globe Control Valve Introduction:
This product includes the ZDLP/ZDLM electronic electric actuator combined with a compact single-seat (sleeve) regulating valve. The actuator features an integrated design with built-in electronic controller modules, eliminating the need for additional servo amplifiers. It offers high precision and easy installation. The characteristics of the sleeve valve are as follows:
- Utilizes a balanced valve core, resulting in minimal unbalanced force, allowing for large pressure differences and stable operation.
- The spool’s large guide surface mitigates oscillations caused by eddy currents and shocks, reducing wear and tear.
- Reduces noise by approximately 10 dB compared to standard single and double seat regulating valves.
- Simple structure, making assembly and disassembly convenient.
