2. Informació de seguretat
ADVERTIMENT: Improper installation, operation, or maintenance of this safety relief valve can result in property damage, serious injury, or death. Always follow all local codes, regulations, and manufacturer instructions.
- Ensure the valve is installed by qualified personnel in accordance with all applicable codes and standards.
- Verify that the valve's set pressure (15 psi) is appropriate for the system it is protecting.
- No tamper with the factory-set pressure. Any adjustments must be performed by authorized personnel using proper calibration equipment.
- Ensure proper discharge piping is installed to safely vent steam or fluid away from personnel and equipment.
- Regularly inspect the valve for signs of damage, corrosion, or leakage.
- Always depressurize the system before attempting any maintenance or inspection.

4. Configuració i instal·lació
Installation of the Apollo Valve 14-200 Series Safety Relief Valve should only be performed by a qualified and licensed professional in accordance with all local and national plumbing and boiler codes.
Passos d'instal·lació:
- Preparació del sistema: Ensure the boiler system is depressurized and cooled before beginning installation.
- Connexió d'entrada: Thread the 2-1/2" male NPT inlet of the valve into the designated female NPT connection on the boiler. Use appropriate thread sealant to ensure a leak-free connection. Do not overtighten.
- Connexió de presa: Connect suitable discharge piping to the 2-1/2" female NPT outlet of the valve. The discharge piping must be adequately sized, sloped for drainage, and routed to a safe discharge point where steam or hot water can be safely released without causing harm or damage. Avoid any restrictions or valves in the discharge line.
- Drain Connection (Optional): If required, connect a 3/8" NPT drain line to the side tapping for condensate drainage.
- Comprovació final: After installation, slowly repressurize the system and carefully inspect all connections for leaks.
5. Principis de funcionament
The Apollo Valve 14-200 Series Safety Relief Valve operates automatically to protect the boiler from overpressure conditions. It is a spring-loaded, direct-acting valve.
- Under normal operating conditions, the system pressure is below the valve's set pressure (15 psi), and the valve remains closed, maintaining system integrity.
- If the system pressure exceeds the 15 psi set point, the force exerted by the pressure on the valve's disc overcomes the spring force, causing the disc to lift and the valve to open.
- Excess steam or fluid is then discharged through the outlet, reducing the system pressure to a safe level.
- Once the system pressure drops below the reseating pressure, the spring force closes the valve, restoring normal operation.
- The valve also features a manual lift lever for periodic testing, which should be performed carefully and only when the system is at a safe operating pressure, to ensure the valve is not seized. Consult boiler operation guidelines for proper testing procedures.
6. Manteniment
Regular maintenance is essential to ensure the continued reliability and safety of your Apollo safety relief valve. All maintenance should be performed by qualified personnel.
Programa de manteniment:
- Inspecció anual: Visually inspect the valve for any signs of external damage, corrosion, or leaks. Check the discharge piping for obstructions.
- Prova de funcionament: Periodically test the valve by manually lifting the lever to ensure the disc moves freely and reseats properly. This should be done in accordance with boiler manufacturer recommendations and safety protocols.
- Neteja: If the valve shows signs of weeping or leakage, it may indicate debris on the seat. A gentle manual lift of the lever while the system is under pressure (if safe to do so per boiler manual) can sometimes clear minor debris. If leakage persists, the valve may need to be replaced.
- Substitució: Safety relief valves have a finite lifespan. It is recommended to replace the valve according to boiler manufacturer guidelines or if it fails any operational tests, shows signs of significant wear, or has discharged frequently.
