The 2000 psi isolation valve is rated at what pressure?

The 2000 psi isolation valve is rated at what pressure?

• A. 1000 psi
• B. 1500 psi
• C. 2000 psi
• D. 2500 psi

Answer: (C)

The key idea is that a valve’s rating is the maximum pressure it can safely seal against. A valve described as a 2000 psi isolation valve is, by specification, rated to withstand up to 2000 psi when closed. That’s why 2000 psi is the correct rating. Applying more than 2000 psi could compromise the valve, while ratings lower than that wouldn’t match the component's stated capability. The other pressures don’t reflect the valve’s rated limit. In practice, you use a valve rated at or above the system’s maximum pressure to ensure a secure isolation.
