带有球体排放结构的相同阀门适用于次氯酸钠（漂白剂）和其他残留液体可能形成腐蚀性结晶体渣滓或由于气体淤积造成压力增加的化学应用场合。阀门的球体具有一个3毫米直径排放孔以补偿内部液体压力。在阀门处于关闭状态下将带有排放孔球体的阀门安装在压力端（上游）上。
Same valve with special ball vent design for sodium
hypochlorite (bleach) and other chemical applications where entrapped
fluids may form caustic crystalline residues and pressure build up from
gases developed. Valve has a 1/8" vent hole
in ball to equalize internal fluid pressures. Install valve with ball
vent on the pressure (upstream) side when in closed position.
