Conbraco 1061410 VLV - REL, 3/4x22 x 1x22 50 psi, BRZ 1, 418, 000 BTU

Description

They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. This relief valve is American Society of Mechanical Engineers (ASME) safety rated for Section IV heating boilers and is suitable for hot water heating boilers and hot water supply systems.Relief valves remove excess pressure or vacuum from a system. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. This Apollo Valve 10-600 series hot water relief valve protects against excessive water pressure due to failure of controls to regulate BTU input. The spring is steel for resistance to corrosion, and a fabric-reinforced, molded EPDM (ethylene propylene diene monomer) diaphragm isolates the spring from water at all times. It has a bronze body, a 50 pounds per square inch (psi) relief pressure, and a 3/4" female National Pipe Thread (NPT) inlet connection and 1" female NPT outlet. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in. The seat is silicone for resistance to high temperatures and is elevated for draining water away from the seat area.
