Frequently Asked Questions
Common questions about valve selection, specifications, and certifications for this industry.
Choose a valve based on the application, flow rate, operating pressure, water quality, pipeline size and required function. Butterfly valves and gate valves are commonly considered for isolation, check valves for reverse-flow prevention, and control valves for flow regulation.
Common options include butterfly valves, gate valves, ball valves, check valves, control valves and knife gate valves. The suitable type depends on whether the system handles clean water, treated water, sludge, wastewater or media containing suspended solids.
Knife gate valves may be suitable for certain sludge and slurry applications, particularly where suspended solids are present. The final selection depends on solids concentration, particle characteristics, pressure, flow conditions and the valve's design.
A butterfly valve uses a rotating disc and is often selected where compact installation and quick operation are important. A gate valve uses a gate to provide isolation and is often considered for applications requiring a relatively unobstructed flow path when fully open. The best option depends on pipeline design and operating requirements.
Consider the chemical composition, concentration, temperature, pressure and corrosion characteristics of the fluid. The valve body, trim, seat and lining materials must be compatible with the actual service conditions. Chemical compatibility should be confirmed before ordering.
Yes. Pneumatic and electric actuators can be used for remote valve operation and automated process control when correctly selected. Consider operating torque, opening and closing time, power or compressed-air supply, control signals, duty cycle and fail-safe requirements.
A correctly selected check valve can help prevent reverse flow. Water hammer may require additional measures based on the pipeline design, flow velocity, pump operation and valve closing characteristics. The complete system should be assessed before selecting a solution.
Yes, but the same valve design may not suit both services. Clean-water lines and wastewater lines can have different requirements for solids handling, corrosion resistance, sealing, maintenance and operating conditions. Select each valve according to its specific application.
