直动型溢流阀按阀芯结构，可分为座阀和滑阀两种形式。座阀结构又分为球阀和锥阀两种；滑阀结构又有滑阀、带阻尼孔的滑阀和差动滑阀三种。直动型溢流阀结构简单， 灵敏度高， 压力受溢流流量变化影响较大，调压偏差大，不适于在高压、大流量下工作，常作安全阀或调压精度要求不高的场合WGAM-20/11/100维拓斯WGAM-20/11/210先导溢流阀VTOZWGAM型先导式溢流阀WGAM-10/10/100WGAM-10/10/210WGAM-10/10/350WGAM-10/11/100WGAM-10/11/210WGAM-10/11/350WGAM-20/10/100WGAM-20/10/210WGAM-20/10/350WGAM-20/11/100WGAM-20/11/210】WGAM-20/11/350WGAM-32/10/100WGAM-32/10/210WGAM-32/10/350WGAM-32/11/100WGAM-32/11/210WGAM-32/11/350WGAM-20/11/100维拓斯WGAM-20/11/210先导溢流阀VTOZWGIR，WGIU型压力控制阀WGIU-10/10/50WGIU-10/10/100WGIU-10/10/210WGIU-10/11/50WGIU-10/11/100WGIU-10/11/210WGIR-10/10/50WGIR-10/10/100WGIRR-10/10/210WGIR-10/11/50WGIR-10/11/100WGIRR-10/11/210VTOZWQV-06型流量控制阀WQV-06/1WQV-06/6/VWQV-06/11WQV-06/16WQV-06/24/VVTOZWDP型单向阀WDR-06/4WDR-10/4WDR-15/4WDR-25/4WDR-06WDR-10WDR-15WDR-25VTOZWHMP，WKM型叠加式溢流阀WHMP-011/50WHMP-012/50WHMP-013/50WHMP-014/50WHMP-015/50WHMP-011/100WHMP-012/100WHMP-013/100WHMP-014/100WHMP-015/100WHMP-011/210WHMP-012/210WHMP-013/210WHMP-014/210WHMP-015/210WHMP-011/350WHMP-012/350WHMP-013/350WHMP-014/350WHMP-015/350WKM-011/50WKM-012/50WKM-013/50WKM-014/50WKM-015/50WGAM-20/11/100维拓斯WGAM-20/11/210先导溢流阀WKM-011/100WKM-012/100WKM-013/100WKM-014/100WKM-015/100WKM-011/210WKM-012/210WKM-013/210WKM-014/210WKM-015/210WKM-011/350WKM-012/350WKM-013/350WKM-014/350WKM-015/350)
