Abstract: A system includes a flow inlet conduit and a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles. An equalization bypass valve (EBV) connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles. The EBV is connected to an equalization conduit (EC). A pressure equalization solenoid is connected to the EC to selectively connect a servo supply pressure conduit and/or a return pressure (PDF) conduit into fluid communication with the EC. An EBV rate limiting orifice (RLO) is connected in the PDF conduit. A bypass conduit branches from the PDF conduit on a first side of the EBV RLO and reconnects to the PDF conduit on a second side of the EBV RLO. An orifice bypass valve (OBV) is connected to the bypass conduit and acts to selectively bypass the EBV RLO.

Abstract: A ball valve includes a housing and has an inlet port, an outlet port and a central ball chamber. A ball member is received within the ball chamber and has a shaft connected to a motor such that the ball member can be rotated. The ball member is movable between a closed position at which it blocks fluid connection between the inlet port and the outlet port and to an open position at which a central passage in the ball member communicates the inlet port to the outlet port. A seal is mounted for movement with the ball member to provide a seal against the housing. A ball valve system is also disclosed.

Abstract: An inline valve includes a sliding piston having a radially outer stop portion with a forward end. A radially inner sliding portion is connected to the radially outer stop portion by an arm. A housing includes an outer housing body surrounding the piston. The housing has a stop surface selectively in contact with the forward end of the radially outer stop portion of the piston to block flow for a housing inlet to a housing outlet. The radially inner sliding portion slides on a support tube. At least a portion of the radially inner sliding portion is formed of a first material having better wear resistance than a second material forming the outer stop portion of the piston. The second material has a greater resistance to high temperature and pressure than the first material. A vent valve for a compressor is also disclosed.
