හැඳින්වීම
This manual provides essential information for the proper installation, operation, and maintenance of the Watts Series 335 ASME rated Boiler Pressure Relief Valve. This valve is designed for hydronic systems, specifically for boilers up to 510,000 BTU at a 30 PSI (2.11 bar) set point. Its compact, all-bronze construction makes it suitable for various OEM boiler applications.

Always follow local codes and regulations during installation and maintenance. Ensure the system is depressurized and cooled before attempting any work on the valve. Wear appropriate personal protective equipment (PPE).
- ටී එපාamper with the factory set pressure.
- Ensure proper discharge piping is installed to safely route discharged water.
- Regularly inspect the valve for signs of corrosion or damage.
සැකසුම සහ ස්ථාපනය
The Watts 0342691 Pressure Relief Valve is designed for straightforward installation. It features a 3/4-inch female threaded inlet and a 3/4-inch FNPT outlet.
- සකස් කිරීම: Ensure the boiler system is completely shut down, depressurized, and cooled. Drain any water from the system if necessary.
- පැරණි කපාටය ඉවත් කරන්න (අදාළ නම්): Carefully unthread the existing pressure relief valve from the boiler.
- නූල් සීලන්ට් යොදන්න: Apply an appropriate thread sealant (e.g., PTFE tape or pipe dope) to the male threads of the new Watts valve.
- නව කපාටය ස්ථාපනය කරන්න: Thread the new valve into the boiler's pressure relief valve port. Tighten securely with a wrench, ensuring not to overtighten.
- Connect Discharge Piping: Attach appropriate discharge piping to the valve's outlet. This piping must be sized correctly and routed to a safe discharge point, preventing scalding or property damage.
- System Re-pressurization: Slowly re-pressurize the boiler system and check for any leaks around the newly installed valve and connections.

මෙහෙයුම් මූලධර්ම
The Watts 0342691 is an automatic pressure relief valve designed to protect hydronic heating systems from over-pressurization. It is factory-set to open at 30 PSI (Pounds per Square Inch). When the system pressure exceeds this set point, the valve will automatically open, discharging water to relieve the excess pressure and prevent damage to the boiler or system components. Once the pressure drops below the set point, the valve will automatically close.
The valve also features a manual test lever. This lever allows for periodic manual testing of the valve's operation. When the lever is lifted, the valve will open, discharging water. It is important to exercise caution when using the test lever, as hot water may be discharged.
නඩත්තු කිරීම
Regular maintenance ensures the longevity and proper function of your pressure relief valve.
- වාර්ෂික පරීක්ෂණය: It is recommended to inspect the valve annually for any signs of corrosion, leaks, or damage.
- අතින් පරීක්ෂා කිරීම: The manual test lever should be operated at least once a year to ensure the valve is not seized and can open freely. When testing, lift the lever briefly to allow a small amount of water to discharge, then release it. Ensure the valve reseats properly without dripping. Note: Some experienced users advise against frequent manual testing on older systems due to the risk of dislodging sediment and causing a leak. Consult a qualified technician if unsure.
- පිරිසිදු කිරීම: Keep the exterior of the valve clean. Do not use harsh chemicals that could damage the bronze finish.
