Where does a low pressure safety and relief valve typically discharge?

A low pressure safety and relief valve is designed to maintain the pressure within a system at a safe level. When the pressure exceeds the set limit, the valve opens to allow steam or other fluids to escape safely. The correct discharge location for this type of valve is typically a designated drain system. This ensures that any discharged fluids are safely removed from the operational area, reducing the risk of accidents or pressure build-up.

In contrast, discharging into a holding tank or directly into the boiler can pose significant risks. Discharging into the atmosphere could also be unsafe if the released steam is not properly managed, while draining directly into the boiler is not advisable as it could lead to a dangerous situation if excessive pressure were to build up. Therefore, directing the discharge into a drain is crucial for maintaining safety and compliance with regulations.
