True or False? On industrial steam boilers, safety valves are required to be mounted in the vertical up position.

Safety valves on industrial steam boilers are designed to operate effectively under specific conditions, and mounting them in the vertical up position is crucial for their proper functioning. When installed vertically, the valve's weight provides a consistent sealing force against the pressure of the steam, allowing the valve to open quickly and relieve excessive pressure as needed. This positioning helps ensure that any built-up pressure can bypass the valve efficiently and minimize the risk of dangerous overpressure conditions.

Additionally, a vertical orientation helps avoid the trapping of steam and debris, which could impede the valve's operation, and promotes proper draining of condensate, ensuring reliability and safety. Therefore, stating that safety valves are required to be mounted in the vertical up position is accurate, as it aligns with safety practices and regulatory requirements in the industry. This positioning is vital for maintaining the safe operation of steam boiler systems.
