电磁换向阀：德国哈威HAWE电磁换向阀G系列阀体用的是全钢制作，受压力比较强，密封好，不渗漏，正常使用的情况下，寿命也相对较长，是非常好的阀门。一般阀门在压力冲击对阀体的影响表现在运作的时候外表会产生细微的裂纹，全额作用压力之下更为明显。而哈威电磁换向阀G系列是不会出现这种情况的，它可以避免这种情况的出现，因为G系列换向阀的阀体内孔所用的是金刚衍磨。阀心经过淬硬和磨削，再经过抛光去掉所有的毛刺，阀心经过这一系列的打磨，其圆度和精度很好，密封间隙距离恰当，能确保泄露小。
 
无压力的零部件的铸造材料一般为锌和铝的模压铸件，像壳体、弹簧盖、地板等等。当然也可以提供墨铸铁做的手动操纵机构壳体，这样的壳体在恶劣工况下或者阀串联链接时使用。
 
在电磁阀的生产材料中，橡胶是一个不可缺少的材料。所以对橡胶性质的了解，是区别不同电磁阀特性的重要依据。NBR丁晴橡胶(nitrilebutadienerubber)耐油性极好，耐磨性较高，耐热性较好，粘接力强。其缺点是耐低温性差、耐臭氧性差，电性能低劣，弹性稍低。此外，它还具有良好的耐水性、气密性及优良的粘结性能。橡胶具有优良的耐油性,其耐油性仅次于聚硫橡胶和氟橡胶，并且具有的耐磨性和气密性。丁晴橡胶的缺点是不耐臭氧及芳香族、卤代烃、酮及酯类溶剂，不宜做绝缘材料。EPDM三元乙丙橡胶(Ethylene-Propylene-DieneMonomer)EPDM最主要的特性就是其优越的耐氧化、抗臭氧和抗侵蚀的能力。

sun插装阀和其阀孔的设计通用性的重要性在于大批量生产。就某一种规格的插装阀为例，为了批量生产，其阀口的尺寸是统一的。此外，不同功能的阀可采用同一规格阀腔，例如：单向阀、锥阀、流量调节阀、节流阀、两位电磁阀等等。如果同一规格、不同功能的阀无法采用不同阀体，那么阀块的加工成本势增加，插装阀的优势就不复存在。 　　插装阀在流体控制功能的领域的使用种类比较广泛，已应用的元件有是电磁换向阀，单向阀，溢流阀，减压阀，流量控制阀和顺序阀。通用性在流体动力回路设计和机械实用性的延伸，充分展示了插装阀对系统设计者和应用者的重要性。由于其装配过程的通用性、阀孔规格的通用性、互换性的特点，使用插装阀完全可以实现完善的设计配置，也使插装阀广泛地应用于各种液压机械。
