Revisamos la válvula de paso.

Revisamos is the nosotros form of revisar. In this kind of sentence, it usually means we check, we inspect, or we examine.

Depending on context, revisar can mean:

• to check
• to inspect
• to review

With something mechanical like la válvula de paso, we inspect/check the shut-off valve is the most natural idea.

Yes. Revisamos can be either:

• present tense: we check / we are checking
• preterite: we checked

Spanish has this overlap in the nosotros form for many -ar verbs.

So this sentence could mean either:

• We check the shut-off valve
• We checked the shut-off valve

Only the context tells you which one is meant.

Because Spanish usually omits subject pronouns when the verb already shows who is doing the action.

• Revisamos already tells you it is we
• So nosotros is optional

You could say Nosotros revisamos la válvula de paso, but it would usually be used only for emphasis, contrast, or clarity.

Válvula de paso is a fixed technical expression. It usually refers to a shut-off valve, stop valve, or isolation valve.

It is not best understood word-for-word as valve of passage. In real usage, it means the valve that controls or cuts off the flow of water, gas, or another fluid.

So it is better to learn válvula de paso as one unit.

Here, de paso is part of the set phrase válvula de paso.

In other contexts, de paso can mean things like:

• in passing
• on the way
• incidentally

But in this sentence, it does not have that everyday meaning. In plumbing or mechanical contexts, válvula de paso is simply the standard term for a valve that regulates or cuts off flow.

In Spanish, definite articles like el, la, los, and las are used more often than in English.

So Spanish commonly says:

• la válvula
• literally the valve

Even if English might naturally say we checked the shut-off valve or just we checked a valve depending on context, Spanish often includes the article when referring to a specific known object.

Yes. Válvula is a feminine noun, so it takes:

• la in the singular
• las in the plural

Examples:

• la válvula
• las válvulas

That is why the sentence uses la válvula de paso.

The written accent in válvula shows where the stress goes:

• VÁL-vu-la

Without the accent, the stress rules of Spanish would suggest a different pronunciation. The accent mark tells you the stress falls on the first syllable.

A simple pronunciation guide is:

reh-bee-SAH-mos lah BAL-boo-lah deh PAH-so

A few notes for Spain:

• v and b sound very similar in Spanish
• z in most of Spain sounds like the th in think, so válvula is not affected, but this is useful to know for other words
• stress falls on:
  • reviSAmos
  • VÁlvula
  • PAso

No. Other verbs could appear depending on the situation:

• comprobar = to verify/check
• inspeccionar = to inspect
• examinar = to examine
• mirar = to look at

But revisar is very natural because it suggests a practical check or inspection. It works especially well in technical, maintenance, or repair contexts.

Yes, it sounds natural, especially in a technical, maintenance, plumbing, or repair context.

A speaker in Spain would understand it as a normal sentence meaning that we checked/inspect the shut-off valve. It has a practical, work-related tone rather than a casual everyday one.

The standard word order is:

Revisamos + la válvula de paso

That is the most neutral and natural order:

• verb first
• then the direct object

Spanish can sometimes change word order for emphasis, but in a normal statement this version is the best one to learn.

Yes. In this sentence, la válvula de paso is the direct object because it is the thing being checked.

You can test it with a pronoun:

• Revisamos la válvula de paso
• La revisamos

Here, la stands for la válvula de paso, which confirms that it is a feminine singular direct object.
