試驗(yàn)點(diǎn)應(yīng)至少包括信號(hào)范圍中的0、25%、50%、75%、100%這5個(gè)點(diǎn),測量儀表基本誤差應(yīng)限于被測試閥基本誤差限的四分之。其次是回差,采用同樣的試驗(yàn)方式,在同一輸入信號(hào)上秘得的正反行程的大差值即為回差。

液壓閥的始終點(diǎn)偏差也是如此,信號(hào)的上限(始點(diǎn))處的基本誤差即為始點(diǎn)偏差;信號(hào)的下限(終點(diǎn))處的基本誤差即為終點(diǎn)偏差。泄漏量較方便地試驗(yàn)介質(zhì)為常溫水,當(dāng)閥的壓差小于350kPa時(shí),實(shí)驗(yàn)壓力按350kPa做,當(dāng)閥的工作壓差大于350kPa時(shí)按允許壓差做;而B試驗(yàn)方試按閥的工作壓差做。
