Set of 2 DN15 Brass Automatic Air Drain Valves for Solar Water Heater Pressure Relief

Premium Material: Our solar water heater is made of high-quality brass, the interior is molded with high-precision parts, and the draining mechanism is stable and reliable.

【Automatic Design】If the system is filled with water or if the system pressure is too high and a complete draining is necessary, this automatic pressure relief valve can operate reliably. As long as there is a pressure difference between the inside and outside of the system, the radiator drain valve continues to vent.

【Easy to Disassemble】To ensure that no water is drained during the process, our automatic drain valve uses a special design for the steam and water separation tank. Easy to disassemble and repair, so the system does not need to be drained.

Package Contents: 2 pieces with DN15 threaded brass automatic heating vent, size: 68.8 × 45 mm, weight: 115 g, pressure rating: PN1.6, removes excess air during the operation of the exhaust and HVAC systems.

【Application】The solar air vent valve is used to release excess air during the operation of the exhaust and HVAC systems, and features high-temperature resistance, rust protection, and reliable sealing.
