A modular valve system includes a modular valve body having an inlet, an outlet, a through-hole, and a fluid flow path between the inlet and the outlet. The modular valve body is used to assemble any one of a pressure regulating valve, a slam-shut valve, or a flow control valve, and the through-hole is configured to receive a component of any one of the pressure regulating valve, the slam-shut valve, and the flow control valve.

Modular valve system

A flow control device includes a valve body defining an inlet, an outlet, and a flow path. A valve seat assembly includes a fitting coupled to the valve body, a seat ring coupled to the fitting and defining a valve seat. The seat ring includes an inner groove formed on an interior surface of the seat ring. A control element is movable relative to the valve body between a closed position, in which the control element engages the valve seat, and an open position, in which the control element is spaced away from the valve seat. The seat ring is coupled to the fitting by snap-fit connection such that a portion of the fitting is disposed in the inner groove of the seat ring.

Valve seat assembly

A valve assembly including a valve body having a first pressure chamber and a second pressure chamber, the pressure of the first pressure chamber being lower than that of the second pressure chamber. The pressure of the second pressure chamber is discharged to the first pressure chamber in response to the change of the pressure of the first pressure chamber. A blocking device is arranged between the first pressure chamber and the second pressure chamber. A valve stem is arranged in the valve body with one end movably contacting the blocking device. A diaphragm is connected to the valve stem and is arranged adjacent to or above the first pressure chamber. When the pressure of the first pressure chamber is changed, the diaphragm forces the valve stem to move by sensing the pressure change of the first pressure chamber.
