阀门材质有不锈钢和青铜可选，派克Bestobell的止回阀装有一个可来回摆动的盘式阀芯，允许停留在所需位置使用。其嵌入式的聚四氟乙烯密封圈，嵌入盘式阀芯，在环境温度下以实现摆动下降时关闭紧密。应用旋启式止回阀，可适应在较低压降时，阀门较大开度能实现较好的流量性能。 Available in Stainless Steel and Bronze, Parker Bestobell's check valves are fitted with a swing return, allowing for use in any position. The PTFE seal incorporated into the valve disc ensures a drop tight shut off at ambient temperatures. With the swing check valve, wide openings also allow high flow rates at low-pressure drops.

标准化部件被用于派克Bestobell摆动阀，截止阀，球阀和闸阀上。派克Bestobell的提升式止回阀通常与截止阀、旋启式止回阀连接，也可以用于与闸阀或球阀连接。 Standardised parts are used in Parker Bestobell's swing valves, globe, ball and gate valves. Parker Bestobell's lift check valves are often specified in conjunction with globe valves and swing check valves would be used in conjunction with gate or ball valves.

提升式止回阀具有锥形阀座设计，无泄漏关闭，因此大限度地提高了安全性和使用性能。 The lift check valves feature a cone seat design for zero leak shut off, therefore maximising safety and performance.
