Question 6

What are the quarter turn valves?

Accepted Answer

Ball valves, Butterfly valves, and Plug valves are rotary motion control valves that require only a quarter turn to come into action.

Question 7

What's the direction of valves?

Accepted Answer

Ball valves and gate valves are bi-directional. Globe valves, check valves, and Y-strainers have arrows on the body to indicate direction.

Question 8

What's the difference between rising stem and non-rising stem of gate valve?

Accepted Answer

In a rising stem gate valve, the stem is visible to show if the valve is open or closed, but it requires more installation space. In a non-rising stem valve, the stem is not visible, the handwheel moves up and down, and it takes up less space.

Question 9

What's the difference of gate valve and globe valve?

Accepted Answer

Gate valves are bi-directional, while globe valves are single-way with a fixed direction. Globe valves offer better sealing as fluid pressure helps keep the disc closed.

Accepted Answer

Check valves are unidirectional valves that allow flow in one direction only. Types include swing, lift (piston and ball), vertical, butterfly, and wafer types (spring return, single disc, double disc).
