Manufacturer profiles associated with Control Valve / Actuator.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The control signal is typically a 4-20 mA analog signal, but can also be 3-15 psi pneumatic or digital signals. The specific signal type depends on the actuator and control system. Always verify with the manufacturer.
The valve body is often made of stainless steel or carbon steel (e.g., WCB to CF8M per ASTM A216/A351). Trim materials include PTFE or elastomers for seals and packing. The actuator housing is typically aluminum or steel. Confirm material compatibility with the process fluid.
Leakage class (IV to VI per IEC 60534-4) indicates the allowable leakage through the valve when closed. Class VI provides tight shutoff. The required class depends on the application. Verify the leakage class with the manufacturer for your specific needs.
Selection requires considering process conditions such as pressure, temperature, flow rate, and fluid properties. Key parameters include nominal diameter, flow coefficient (Cv), rated travel, and actuator type. Always consult the manufacturer or supplier to confirm that the selected model meets your requirements and standards.
