The pure gum rubber sleeve of the Type A Valve offers excellent abrasion resistance, and since the Type A uses only air pressure to operate, there are no moving parts to break or wear out.

型夹管阀采用的纯树脂橡胶具有优异的抗磨损能力，因为A型夹管阀只是采用气压进行操作，因此没有活动部件会断裂或磨损。

This system is quickly becoming obsolete due to the introduction of the DIS and coil per cylinder systems with fewer moving parts and wear factors.

该系统正在迅速落伍，由于DIS和有更少运动部件和磨损因素的每罐线圈的引入，测量火花塞的电压是要求在不同条件下能跳掉插头。
