Frequently asked

Valve questions, answered.

Quick answers to the questions our engineers hear most often. Still unsure? Send us your application details and we’ll confirm the right choice.

How do I know which valve is suitable for my application?

Valve selection depends on the media, pressure, temperature, pipe size, valve function, material compatibility, sealing requirement, and whether the valve is for isolation, throttling, or control.

What details should I prepare before inquiring about a valve?

Helpful details include the media, pipe size, pressure rating, temperature, line connection, valve material, seat material if required, and whether the valve will be manual or automated.

Can Flowtork help assess valves for steam or severe service applications?

Yes. Steam and severe service applications require careful review of pressure, temperature, valve design, material compatibility, sealing performance, and operating conditions.

What should be checked before replacing an existing valve?

The valve size, pressure rating, connection type, material, face-to-face dimension, application, and installation conditions should be reviewed before selecting a replacement.

Are spare parts available for valves?

Spare parts may be available depending on the valve brand, model, size, material, and component requirement. Common replacement items may include seats, seals, gaskets, discs, stems, or repair kits, depending on the valve type.

Why is valve maintenance important?

Valve maintenance helps prevent leakage, difficult operation, corrosion-related issues, seat damage, and unexpected downtime. Regular inspection is especially important for critical or frequently operated valves.

Can Flowtork assist with pipe replacement, mating flanges, or related installation items?

Depending on the project scope, Flowtork can assist with pipe replacement, mating flanges, and other appurtenances needed for proper installation.

Can valves be supplied with actuators?

Yes. Valves can be paired with actuators based on the valve torque, control requirement, power supply, operating environment, and process conditions.
