1. නිෂ්පාදන අවසන්view
This manual provides essential information for the safe and effective use of the Apollo Valve 13-213 Series Bronze Safety Relief Valve. This valve is designed for protecting small to medium low-pressure steam heating boilers by removing excess pressure from the system.
ප්රධාන ලක්ෂණ ඇතුළත් වේ:
- Relief pressure preset of 15 psi for releasing excess pressure.
- 1-1/4" male NPT threaded inlet for connecting to a female NPT threaded connection.
- Cast bronze body and steel spring for corrosion resistance.
- Flat seat, PTFE-faced disc for positive seal.
- ASME safety rated for Section IV heating boilers.

- Ensure proper discharge piping is installed to safely vent steam away from personnel and equipment.
- Regularly inspect the valve for signs of wear, corrosion, or damage.
3. Components and Design
The Apollo Valve 13-213 Series is constructed with durable materials designed for steam applications. Key components include:
- ශරීරය: Cast bronze for corrosion resistance and durability.
- ආසනය: Flat seat design with a PTFE-faced disc for a positive seal, resistance to moisture, and high temperatures. This design also facilitates positive drainage of condensate.
- වසන්තය: Steel spring mechanism for reliable pressure relief.
- සම්බන්ධතා: 1-1/4" male NPT inlet and 1-1/2" female NPT outlet for secure pipe connections.

4. පිහිටුවීම සහ ස්ථාපනය
Proper installation is critical for the safe and effective operation of the relief valve. Consult a qualified professional if you are unsure about any step.
- පද්ධති සකස් කිරීම: Ensure the steam boiler system is completely shut down, depressurized, and cooled before beginning installation.
- ආදාන සම්බන්ධතාවය: Thread the 1-1/4" male NPT inlet of the relief valve into the corresponding female NPT connection on the boiler. Use appropriate thread sealant (e.g., PTFE tape or pipe dope) suitable for steam applications. Tighten securely to prevent leaks, but do not overtighten.
- පිටවීමේ සම්බන්ධතාවය: Connect the 1-1/2" female NPT outlet of the relief valve to a discharge pipe. This pipe must be adequately sized and routed to safely vent steam to an open atmosphere or a designated safe discharge area, away from personnel and equipment. Ensure the discharge pipe has no obstructions, traps, or valves that could impede flow.
- දිශානතිය: Install the valve in an upright position, ensuring the discharge path is clear and unobstructed.
- කාන්දු පරීක්ෂාව: After installation, slowly bring the system up to operating pressure and carefully check all connections for leaks. Address any leaks immediately.
5. මෙහෙයුම් උපදෙස්
The Apollo 13-213 Series Safety Relief Valve operates automatically to protect the boiler from overpressure conditions. It is designed to open when the system pressure reaches its factory-set relief pressure of 15 psi.
- ස්වයංක්රීය ක්රියාකාරිත්වය: When the boiler pressure exceeds 15 psi, the valve will automatically open to discharge steam, reducing the pressure within the system.
- Reseating: Once the system pressure drops below the reseating pressure (typically slightly below the set pressure), the valve will automatically close, restoring the seal.
- Manual Test Lever: The valve is equipped with a manual test lever. It is recommended to periodically test the valve by lifting the lever to ensure it operates freely and discharges steam. This should be done carefully and only when the boiler is at a safe operating pressure, ensuring the discharge path is clear. Refer to boiler manufacturer guidelines for specific testing frequency.
6. නඩත්තු කිරීම
Regular maintenance ensures the longevity and reliable operation of your safety relief valve. Always ensure the system is depressurized and cooled before performing any maintenance.
- දෘශ්ය පරීක්ෂාව: Periodically inspect the valve for any signs of external damage, corrosion, or leaks. Check the discharge piping for obstructions.
- අතින් පරීක්ෂා කිරීම: As mentioned in the operating instructions, perform periodic manual tests using the lever to ensure the valve opens and closes freely.
- පිරිසිදු කිරීම: Keep the exterior of the valve clean. Do not use harsh chemicals that could damage the bronze or other components.
- වෘත්තීය පරීක්ෂණය: It is recommended to have the valve inspected and serviced by a qualified professional at regular intervals, as per industry standards or local regulations.
7. දෝශ නිරාකරණය
This section addresses common issues you might encounter with your safety relief valve.
| ගැටලුව | විය හැකි හේතුව | විසඳුම |
|---|---|---|
| Valve Leaks Continuously | Debris on seat, damaged seat/disc, incorrect system pressure. | Manually cycle the valve to clear debris. If leaking persists, the valve may need replacement or professional servicing. Verify system pressure is below set point. |
| Valve Does Not Open | System pressure not reaching set point, valve stuck due to corrosion/deposits, incorrect valve for application. | Verify boiler pressure gauge accuracy. Attempt manual test. If stuck, valve may need replacement. Ensure valve specifications match system requirements. |
| Valve Opens Prematurely | System pressure fluctuating, valve spring fatigue, incorrect valve for application. | Monitor system pressure stability. If valve is old or frequently cycles, it may need replacement. Ensure valve specifications match system requirements. |
For issues not listed or if solutions do not resolve the problem, contact a qualified technician or the manufacturer.
