Designed for acid-corrosive fluid control scenarios, this assembly is widely applied in power and petrochemical industries, including:
What makes the KOSO 301R valve acid-resistant?
It adopts acid-resistant alloy materials (316/316L) for the valve body and acid-proof sealing parts, specially processed to resist corrosion from various acidic media in power and petro processes.
Can the 6300RB pneumatic cylinder actuator be used alone?
Yes, the 6300RB is a standalone universal pneumatic cylinder actuator, compatible with most industrial ball valves and butterfly valves of matching specifications.
What actuation modes are available for fail-safe operation?
The single-acting 6300RB actuator supports fail close or fail open modes via spring return; double-acting version can achieve fail lock with auxiliary accessories.
How to select the right connection type for the 301R valve?
Flanged connections (ANSI/JIS) are recommended for large-diameter and high-pressure pipelines in power/petro plants; threaded connections for small-diameter, low-pressure branch pipelines.
What maintenance is needed for acid-resistant performance?
Regularly inspect the valve sealing and anti-corrosion coating, clean the valve core and seat, and replace worn acid-resistant seals in time to maintain anti-corrosion and sealing performance.
Is the assembly compatible with digital control systems?
Yes, it can be equipped with pneumatic positioners, limit switch boxes and transducers to connect with PLC, DCS and other industrial digital control systems.
Can custom materials be selected for extreme acid corrosion?
Yes, duplex stainless steel or Hastelloy can be customized for the valve body for ultra-strong acid-corrosive media in special petrochemical processes.
