Title:
PRESSURE-BALANCED FLUID PRESSURE REGULATORS
Document Type and Number:
WIPO Patent Application WO/2013/006403
Kind Code:
A3
Abstract:
Pressure-balanced fluid pressure regulators are described. An example fluid regulator includes a fluid flow control member disposed within a fluid flow passageway of a valve body and moves relative to a seat ring to modulate fluid flow through the fluid flow passageway. A valve stem couples the fluid flow control member to an actuator. The valve stem has a pathway to allow fluid from an inlet of the fluid flow passageway to flow across the flow control member between a first side of the flow control member and a second side of the flow control member opposite the first side to pressure-balance the fluid flow control member.
