Document Type and Number:
Japanese Patent JPH05509375
Kind Code:
A
Abstract:
A flow control and pressure reducing valve has a valve body (250) with an inlet chamber (256) and outlet chamber (257) separated by a partition plate (258). A plurality of passages (265) are formed in the valve body spaced circumferentially around the partition plate (258) and have an inlet portion opening into the inlet chamber (256) and an outlet portion opening into the outlet chamber (257). Elastomeric flow control means (266) are positioned in the passages and are responsive to pressurized fluid introduced therein to control flow of fluid through the passages (265) around the partition plate. The valve configuration allows the mounting of inlet and outlet gates within the inlet and outlet chambers to eliminate the need for separate gate valves. An auxiliary flow passage may be provided through the partition plate and flow controlled therethrough to increase the flow capacity of the valve yet still provide full flow and pressure control. Air inlet and relief valves (279) may also be provided as an integral part of the valve.
