摘要 |
A regulator having a valve body defining a flow-path for a fluid and having a valve seat, an actuator casing coupled to the valve body, a control member disposed within the actuator casing and adapted for displacement relative to the valve body and the valve seat for regulating a flow of the fluid through the flow-path by moving between an open position and a closed position wherein the control member engages the valve seat, and a spring operatively coupled to the control member and biasing the control member toward the open position. The control member includes a surface facing the valve seat that is recessed. The recessed surface may be a counter-bore, or may have a convex shape, conical shape, or other appropriate recessed surface. So configured, the regulator displaced improved stability in high inlet pressure, low output pressure, high flow rate implementations. |
