Siemens valve advantages:
High thrust - suitable for high flow rates and large pressure differentials
Safe and reliable - able to ensure safe and reliable operation even under extremely harsh conditions
Economy - sturdy structure, long service life

Suggestions for actuator selection:

For applications that prioritize high thrust and safety, long stroke valves used in conjunction with electric hydraulic actuators are undoubtedly the best choice. Electric hydraulic actuators are a choice for demanding regional heating applications and large-scale equipment. They have excellent performance in terms of positioning, robustness, agility in spring reset, and many other functional aspects. Electric hydraulic actuators are an ideal choice for controlling sub circuits in machine rooms and high flow systems.
