Electric O cast steel WCB flange ball valve

Q941F electric O flange ball valve

This product adopts an electric actuator, flange connection, and O spherical flow channel. The model field on the current page is Q941F-16C/16P, with a caliber of DN25-DN800. The material field also includes WCB, CF8, and CF8M. Therefore, the actual valve body material should be confirmed according to the specific product configuration and order.

What is the main function of the ordinary O ball valve?

The ordinary O ball valve is mainly used for opening, closing, and cutting off pipelines. Even if the actuator can stay in the middle position, it cannot be directly recognized as a professional continuous regulating valve; Continuous throttling requires verification of the spherical flow channel, valve seat, allowable pressure difference, and actual flow characteristics.

How to choose PN16, Class150, and 10K?

The three belong to configurations under different standard systems and cannot be directly considered equivalent. It should be checked separately based on the design standards, flanges, materials, and design temperatures used in the project.

Selection of execution mechanism

The electric actuator needs to be configured according to the actual opening and closing torque, power supply, action requirements, control mode, valve position feedback, and on-site environment. Control signals and communication protocols shall not be used as default features for all products.

Frequently Asked Questions

Can Q941F ordinary O ball valve be throttled for a long time?

It cannot be generalized that ordinary O ball valves are mainly used for opening, closing, and cutting off. Long term throttling requires separate evaluation of the valve seat and operating conditions.

Are WCB and CF8 configured with the same material?

No, the selection should be based on the medium, temperature, corrosiveness, and project material requirements.

Is 4–20mA standard for electric ball valves?

No, it is only applicable when configuring corresponding regulating actuators and control modules.
