How often should you check an API 600 gate valve?
Check the valve every six months. Look for leaks, rust, or worn parts. Lubricate moving parts and replace damaged seals to keep it working well.
What’s the difference between rising and non-rising stem gate valves?
Rising stem valves show their position as the stem moves up or down. Non-rising stem valves don’t move, making them good for small spaces. Pick one based on your space needs.

Yes, they can if made from materials like stainless steel or alloy steel. These materials resist rust and chemical damage, keeping the valve safe to use.
How do you know if an API 600 gate valve meets standards?
Look for the API Monogram on the valve. This mark shows it meets API 600 rules. Manufacturers are checked regularly to keep this certification.
Tip: Always check the valve’s certifications and materials before buying.
