ABSTRACT:
A pressure-operated valve is disclosed including a choke positioned between one or more inlet ports to the valve and a flow port within the valve defined by a seat to which a valve element may be sealed to close the valve. The choke includes one or more orifices to provide a constricted flow path such that control fluid, entering the inlet port, experiences a pressure drop before reaching the flow port, whereby fluid pressure downstream of the flow port may effectively control the configuration of the seat-and-valve element combination. The choke, which is sealed within the valve to prevent fluid flow around the choke, may be positioned at the inlet port to receive fluid flow into the valve.
