    Abstract: A balance or flow limiting valve features a valve body/member having a flow rate indicator/scale containing setting having printed flow rates calibrated in units of measure in volume per time increment between a minimum flow rate position (MIN) and a maximum flow rate position (MAX); and a knob/handle having a position indicator and being moveable to any continuous position on the flow rate indicator/scale between MIN and MAX in response to a user applied force, where the relationship between the flow rate indicator/scale and the position indicator is based on calibrated flow characteristics of the balance or flow limiting valve. The user can set an exact desired flow rate in one operation by moving the knob/handle to a desired position between MIN and MAX without consulting a printed flow curve or balance calculator to determine the desired exact flow rate.

    Abstract translation: 平衡阀或流量限制阀具有阀体/构件,该阀体/构件具有流量指示器/刻度尺含有设定,其具有以最小流量位置(MIN)和最大流量位置之间的每时间增量的体积测量单位校准的印刷流量 (MAX); 以及具有位置指示器并且可响应于用户施加的力在MIN和MAX之间的流量指示器/刻度上的任何连续位置移动的旋钮/手柄,其中流量指示器/刻度与位置指示器之间的关系为 基于校准的平衡阀或限流阀的流量特性。 用户可以通过将旋钮/手柄移动到MIN和MAX之间的所需位置,而不必咨询打印​​的流量曲线或平衡计算器来确定所需的精确流量,从而在一个操作中设置精确的期望流量。

    Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion, and has two sides, a first side to respond to the fluid flow in a first direction and move the check valve portion away from a fluid opening to the one or more open positions depending on the fluid flow to allow the fluid to flow through the fluid opening, and a second and opposing side to respond to fluid flow in an opposite direction through the fluid opening and move the check valve portion towards the fluid opening to the closed position to seal the fluid opening and stop fluid flow. The check valve portion a near-sloped portion formed nearest to the pivot portion, having a near-sloped contoured surface curving away from the pivot point to a first point of inflection with a first curvature, and a far-sloped portion formed farthest from the pivot portion, having a far-sloped contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature, the near-sloped portion and the far-sloped portion combining to form a combined surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
