Our control valves are fluoroplastic-lined pneumatic control butterfly valves that come together with the equipment; their main advantage is corrosion resistance, which is very important.
Should I use an imported or a domestic Fisher control valve? Imported ones are of good quality
For the main system control valves, imported fluorinated butterfly valves are often used; however, the butterfly valve needs to be manually adjusted to the desired flow rate, and switching to an automatic control method can ensure greater stability
For caustic soda control valves, it is recommended to use 316L stainless steel bellows globe valves. Valve seat made of 316L stainless steel; valve cover made of Stellite soft alloy for a tight seal with no leaks. Valve positioners can be selected as domestic or imported, depending on the operating conditions. The price is only about half of that of imported ones. The manufacturer’s warranty period is one and a half years. Consultation phone: 18660528336 (Mr. Liu)
This depends on the process conditions and requirements; different media and temperatures require different valves
The selection of control valves depends on the location where they will be used; it is recommended to use imported valves for critical locations. In recent years, the quality of domestically produced control valves has also been quite good
