What does API 607 mean?

What does API 607 mean?

API 607 provides fire test criteria for quarter-turn valves and other valves with nonmetallic seating under pressure, whereas API 6FA provides the fire testing requirements for API 6A and API 6D valves. API 6FA is applicable for metal seated valves.

What is the latest edition of API 607?

Product Details: Revision: 7th Edition, June 2016. Published Date: June 2016.

What is a fire safe butterfly valve?

A fire safe butterfly valve can have various body designs like wafer, lugged and double flanged. This type of butterfly valve is configured to withstand harsh conditions, extreme temperature rating and nominal pressure.

What is fire safe test?

Fire Safe Testing of valves These tests determine the resistance of fire-safe-valves to a burn under controlled conditions as defined in common industry standards like: ISO 10497, API 607, 6FA, 6FB, 6FD.

What is quarter turn valve?

Quarter turn valves require just that, a quarter of a turn. These are a newer type of valve that uses a ball valve design. You have to turn the valve 90 degrees to move the hollowed-out ball. The ball blocks the path once you turn the valve handle.

When Should a valve be fire safe?

The fire safety test, as conducted by TÜV SÜD, ensures that the valves demonstrate minimal leakage and can still be operated in case of fire. The valves are placed under pressure (75% of the max. working pressure) with water, and must withstand a fire (temperatures between 750 – 1000°C) for 30 minutes.

How do you test a butterfly valve?

To test a butterfly valve’s sealing performance, the test medium should be introduced from the medium inflow end. Make sure the butterfly plate is opened, the other end closed, and inject the test medium at the pressure specified by your testing requirements.

Is Gate valve fire Safe?

For this reason the first types of valves to be considered fire-safe were gate and globe valves because of their metal-to-metal seating.

Which are better multi-turn or quarter turn valves?

Most will say quarter-turn for build quality and ease of use. Some will stick with multi-turn compression valves because they’re used to them, and trust them. Chances are that whatever you choose, it will work fine for years.

What are the test for valves?

Closure tests are required to test the closure mechanism of several types of valves, including gate, globe, plug, check, and ball valves. Shell leakage tests are required for valves that are used in “full open” and “full closed” service, such as check, stop, and isolation valves.
