派克的座阀型单向阀设计用于最严酷的应用工况。由于采用带有导向的座阀设计，此类阀在流量大至132 gpm及压力高达 6000 psi的工况下，仍能稳定地工作。其最普通的型式为采用球形座阀的设计，并对阀芯与阀座采用级差硬化处理，这些特征保证了此类阀的泄漏量低至每分钟不超过5滴，且因磨损特性得到了改善，使用寿命铰长。
派克球型单向阀的设计为：通过弹簧将一个球形阀芯压靠在阀座上。这样，可阻止液流在一个方向上流动，但在相反方向上，当压力高至能推动球阀芯离开阀座表面时，便允许液流通过，该允许液流通过时的压力就称为开启压力。通过使用硬化的球阀芯及精加工阀座，此类单向阀在关闭方向上的泄漏量不超过每分钟5滴。
派克可提供规格及开启压力众多的各种类型单向阀,其耐用的座阀式设计，对大量的工业或工程机械应用均十分理想，这些应用领域包括：建筑、农业、垃圾处理、起重机、载重卡车、工业动力单元、压机、锻造以及材料处理。
