Safety relief / holding pressure valve (AX742) installed in the pipe in high-rise buildings, fire water supply system and other water supply system, water supply pipeline when the pressure exceeds the pressure relief valve set pressure, the pressure relief valve opens automatically rapid relief, protection of pipeline safety, also can be used for holding pressure valve, ensure the main valve the upstream water supply pressure.
Product overview
■ safety relief valve (AX742X) used in high-rise building general test cycle system, the pressure relief can be more than the safety valve pipe set value of the pressure release, to prevent a sharp increase in pressure piping and equipment damage, and to maintain pressure on the security value of a pipe
■ safety pressure holding valve (AX741X) used in industrial and mining enterprises, high-rise buildings, fire water supply and drainage system to reduce dynamic pressure, static pressure of the occasion, the upstream higher pressure drop to meet the requirements of the downstream normal pressure. Can replace the intermediate water tank, the resistance is small, large flow, the outlet pressure regulating range is wide, can reach the valve before the pressure of 10% ~ 80%
