FAQ
What is the difference between 331L and 331T models?

The 331L features a L-port ball for flow diversion, while the 331T has a T-port ball for flow mixing and diversion, both optimized for different process control needs.

Can the 6300RB actuator be configured for fail-safe operation?

Yes, the 6300RB actuator is available in single-acting (spring return) configuration for fail close or fail open fail-safe operation as required.

What media can these valves handle?

They are suitable for water, oil, gas, steam, and most non-corrosive/corrosive process fluids (material dependent).

Is the assembly compatible with digital control systems?

Yes, it can be equipped with positioners and transducers for integration with PLC, DCS and other digital industrial control systems.

What maintenance is required for the valve-actuator assembly?

Regular inspection of seals and pneumatic connections, periodic lubrication of moving parts, and filter replacement for pneumatic supply (per operation manual).

Can custom materials be selected for specific applications?

Yes, custom body, ball and seat materials are available for high temperature, high pressure or corrosive media applications.

What is the typical service life of the assembly?

With proper installation and regular maintenance, the assembly delivers a long service life of over 100,000 cycles for standard industrial use.
