Frequently Asked Questions

Q: What are the primary advantages of stainless steel flanged ball valves over WCB valves?

Stainless steel valves offer superior corrosion resistance (rust, pitting, and chemical erosion), making them ideal for chemical plants and marine environments where WCB carbon steel would fail prematurely.

Q: How does the lockable handle benefit industrial safety?

Lockable handles allow operators to secure the valve in an open or closed position with a padlock, preventing unauthorized access and accidental actuation during critical maintenance or in high-risk environments.

Q: What is the correct sequence for tightening bolts during installation?

Bolts should be tightened in a diagonal, criss-cross pattern using a calibrated torque wrench to distribute pressure evenly and avoid crushing gaskets or deforming the valve body.

Q: Can stainless steel flanged ball valves be used for radioactive media?

Yes, the robust construction and material properties of stainless steel ball valves make them suitable for controlling radioactive media, along with oil, mud, and corrosive liquids.

Q: Why is pipeline flushing necessary before installing a new valve?

Flushing removes welding debris, dust, and foreign materials that could otherwise scratch the precision-machined sealing surfaces or interfere with the rotation of the ball.

Q: Which international flange standards does Ningjin Thriveon support?

Our valves are manufactured to conform to ANSI and DIN standards, ensuring reliable connections and pressure integrity for clients in the US, Europe, Middle East, and beyond.
