4 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official ZHA/B series are multi-spring pneumatic diaphragm actuators for linear control valves, with direct or reverse action and handwheel options. Provide valve connection, stroke, thrust and air supply; piston or electric actuator capability cannot be inferred from catalogue names.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
For electric actuators, the control signal is typically 4–20 mA per IEC 60381, with a supply voltage of 24 V DC ±10%. Pneumatic actuators use supply pressure of 0.4–0.8 MPa per ISO 5211. Confirm the exact signal type and range for your model.
Diaphragm materials include EPDM, PTFE, and FKM, as per ASTM D2000. The choice depends on chemical compatibility with the process media. Consult the manufacturer for specific recommendations.
The ingress protection rating is IP54–IP65 per IEC 60529, depending on the model. Higher ratings are available for harsh environments. Verify the rating for your specific actuator.
