Frequently Asked Questions

Common questions about valve selection, specifications, and certifications for this industry.

Which industrial valves are used in chemical processing plants?

Ball valves, butterfly valves, gate valves, globe valves, diaphragm valves and control valves may be used in chemical plants. Selection depends on the chemical composition, concentration, operating pressure, temperature and required isolation or flow-control function.

Which valves are suitable for handling corrosive chemicals and acids?

Suitable stainless steel, alloy, diaphragm or lined valve designs may be considered depending on the chemical and operating conditions. The valve body, trim, seat, seals and lining must be compatible with the specific chemical, its concentration and temperature.

When should I choose a PTFE-lined valve for chemical applications?

PTFE-lined valves may be considered when chemical compatibility and corrosion resistance are important. Confirm compatibility with the process fluid, concentration, temperature, pressure, vacuum conditions where applicable, and the lining manufacturer's limitations before selecting the valve.

What is the difference between a stainless steel valve and a PTFE-lined valve?

A stainless steel valve uses a metallic body and wetted components, while a PTFE-lined valve has a protective PTFE lining over specified internal surfaces. The better choice depends on chemical compatibility, pressure, temperature, mechanical requirements and the valve design.

Which valves are suitable for chemical dosing and precise flow control?

Control valves and suitably designed diaphragm or ball valves may be considered, depending on the dosing system and required accuracy. Selection should account for flow rate, pressure differential, chemical properties, leakage requirements and compatibility of wetted materials.

How do I select the right valve material for chemical processing?

Identify the exact chemical, concentration, temperature, pressure and cleaning conditions. Check the compatibility of the body, trim, seat, seals and lining using reliable chemical-resistance data and the manufacturer's technical documentation.

Can pneumatic and electric actuated valves be used in chemical plants?

Yes. Actuated valves can support remote isolation and automated process control. Consider operating torque, cycle frequency, available power or compressed air, control signals, fail-safe requirements and any hazardous-area protection required by the application.

How can chemical plant operators reduce valve corrosion and leakage?

Select valves with materials and sealing arrangements suited to the actual process conditions. Correct installation, appropriate operation, routine inspection and preventive maintenance can help reduce corrosion-related damage and leakage.

What should I check before purchasing valves for highly corrosive chemical service?

Confirm the exact chemical composition, concentration, operating and cleaning temperatures, pressure, wetted-material compatibility, seal selection and any lining limitations. Request the relevant technical documentation and verify suitability for the intended service before ordering.
