⚙️ Which Valve Types Are Compatible with SIRCA Actuators?
🔹 1. Ball Valve
✅ Most suitable – ball valves require high torque but short stroke (90° rotation). SIRCA actuators are the optimal solution.
Ideal for: converting manual lever ball valves to automatic control
Applications: water supply, compressed air, oil, chemical systems
Actuator types: pneumatic or electric (90° rotation)
🔹 2. Butterfly Valve
✅ Perfectly compatible – butterfly valves also operate with 90° rotation and can be easily mounted using the ISO 5211 standard flange.
Applications: HVAC, fire-fighting systems, water treatment
Advantages: lightweight actuator, ideal for slim-body butterfly valves
Torque range: suitable for DN50 to DN400 sizes
🔹 3. 3-Way Ball Valve
✅ SIRCA actuators support 90° or 180° rotation, allowing precise control of L-port or T-port 3-way ball valves.
Applications: flow diversion, mixing control
Options: modulating actuators with positioning control
Available in 3-point control or analog signal (4-20mA) electric versions
🔹 4. Plug Valves & 2-Piece Industrial Ball Valves
✅ SIRCA actuators can be adapted for plug valves or heavy-duty 2-piece ball valves, ensuring precise automatic operation—even in corrosive or high-vibration environments.
🔹 5. Custom Check Valves with Actuation Mechanisms
➡️ For check valves requiring custom actuation mechanisms, SIRCA actuators can be engineered to match OEM-specific mounting designs or factory-built configurations.
