Meaning and Definition
A valve that opens and closes a port by sliding a flat plate or disc across it, typically used to control fluid flow in engines and pumps.
In broader engineering contexts, any valve mechanism where the sealing action is achieved by linear sliding motion rather than rotation or hinging. In metaphorical use, can describe a person or system that regulates flow or access in a straightforward, binary manner.
Dialectal Variation

Differences
No significant lexical difference. Minor potential differences in related terminology (e.g., 'slide valve gear' vs. 'valve train' in broader engine contexts).
Connotations
Neutral technical term in both varieties.
Frequency
Equally low-frequency in general language but standard in relevant engineering fields in both regions.

Frequently Asked Questions
They are similar in principle (linear sliding gate), but 'gate valve' is a broader category for pipeline valves, while 'slide valve' is often more specific to engine and pump intake/exhaust systems.
In historical or museum contexts involving steam engines, certain types of air compressors, and in some textbook diagrams of basic valve mechanisms.
It is a standard historical and descriptive term in engineering, but many modern applications use more specific or advanced valve types (e.g., spool valves in hydraulics).
No, it is exclusively a noun. The action is 'to actuate a slide valve' or 'the valve slides'.
