公称压力：表示安全阀在常温状态下的Zui高许用压力，高温设备用的安全阀不应考虑高温下材料许用应力的降低。安全阀是按公称压力标准进行设计制造的。
开启压力：也叫额定压力或整定压力，是指安全阀阀瓣在运行条件下开始升起时的进口压力，在该压力下，开始有可测量的开启高度，介质呈可由视觉或听觉感知的连续排放状态。
排放压力：阀瓣达到规定开启高度时的进口压力。排放压力的上限需服从国家有关标准或规范的要求。
超过压力：排放压力与开启压力之差，通常用开启压力的百分数来表示。
回座压力：排放后阀瓣重新与阀座接触，即开启高度变为零时的进口压力。
启闭压差：开启压力与回座压力之差，通常用回座压力与开启压力的百分比表示，只有当开启压力很低时采用二者压力差来表示。
