Which valve provides pressure-relieving protection in sections of piping and hose where lp-gas can be isolated?

• A. Hydrostatic Relief Valve
• B. Pressure relief valve
• C. Check valve
• D. Safety valve

Answer: (A)

When LP-gas piping can be isolated, trapped liquid propane can heat up and expand, causing pressure to rise in that closed section. A hydrostatic relief valve is designed specifically for this situation: it opens when pressure in the isolated segment becomes too high and vents the gas to a safe location, preventing a rupture or burst in the piping or hose. This targeted protection is different from a general pressure relief valve, which is typically used on tanks or vessels to protect against overpressure, or from a check valve, which merely blocks backflow, or a safety valve, which serves a different equipment-specific purpose. In short, the hydrostatic relief valve provides the necessary protection for isolated piping sections where LP-gas can accumulate and expand.
