<p>A valve manifold that is adapted to be positioned between a main flow line and a measuring instrument, including a body; a pair of fluid flow passages in said body, each having one port for coupling with the main flow line and an opposite end port for coupling with the measuring instrument; a pair of valve members for controlling the fluid flow through the respective pair of fluid flow passages; and a pair of handles for respectively controlling said pair of valve members. Each of the valve members includes a control end coupling with a respective handle to control the position of the valve member and a valving end adapted for positioning in a valve passage that extends transverse to the fluid flow passage. Each valve member further has a resilient seal member that is supported by either the body or valve member and that, in a closed position, provides a seal about the fluid flow passage between the valve member and body so as to inhibit fluid flow through the fluid flow passage, and that, in at least a partially open position, enables fluid flow through the fluid flow passage.</p> |
