Question 1

What is the difference between a ball valve and a gate valve?

Accepted Answer

Ball valves use a rotating ball for quick quarter-turn shut-off and are ideal for frequent operation. Gate valves use a sliding gate mechanism, open slowly, and are best for infrequent operation where fully open or fully closed positions are needed. Ball valves are more compact and have less pressure drop.

Question 2

Can I use a ball valve for throttling or flow control?

Accepted Answer

Ball valves are designed for on/off service, not throttling. Partial opening can damage the ball and seats due to high velocity flow. For flow control, use a globe valve or butterfly valve instead. Ball valves should be operated fully open or fully closed.

Question 3

What does full port vs. standard port mean?

Accepted Answer

Full port (or full bore) valves have a ball opening equal to the pipe size, allowing unrestricted flow with minimal pressure drop. Standard port valves have a smaller opening (typically one size smaller), causing more pressure drop but at lower cost. Choose full port for high-flow applications.

Question 4

Are these valves suitable for natural gas?

Accepted Answer

Yes, our gas-rated ball valves are EN 331 certified for natural gas and LPG service. They feature enhanced sealing, safety-rated PTFE seats, and lockable handles. Always specify gas service when ordering and ensure professional installation by licensed gas fitters.

Question 5

How often do ball valves need maintenance?

Accepted Answer

Our brass ball valves require minimal maintenance. In typical water service, they can operate 10+ years without service. For best results, cycle the valve (open/close) every 6-12 months to prevent seat sticking. Replace if leakage occurs or handle becomes difficult to operate.

Question 6

Can ball valves be installed in any orientation?

Accepted Answer

Yes, ball valves can be installed horizontally, vertically, or at any angle. The handle can be positioned for convenient access. However, avoid installing with handle pointing down in overhead locations where it could be a head hazard.

Question 7

What pressure rating do I need?

Accepted Answer

For residential water systems, PN16 (16 bar/232 psi) is typically sufficient. Commercial buildings may require PN25. Industrial applications often need PN40 for safety margin. Always choose a pressure rating higher than your system's maximum pressure. Our team can help you select the right rating.

Question 8

Do you offer actuator-ready valves for automation?

Accepted Answer

Yes, we offer ball valves with ISO 5211 mounting pads for electric or pneumatic actuators. These are ideal for remote operation, automation systems, and applications requiring motorized control. Custom specifications available with MOQ of 500 units.
