摘要： A hydraulic valve having a body defining an inlet and an outlet. A motor is supported by the body and operates a shaft extending through an interior of the body, the shaft terminating in a gate. A spring is supported within the housing and influences the gate in an open position to permit fluid flow between the inlet and outlet. Upon the occurrence of a pressure differential resulting from a fluid flow through the inlet exceeding a biasing force of the spring, the gate is caused to displace against a valve seat communicating the inlet with the outlet in order to interrupt fluid flow in a standby mode and to define a closed position. The motor operates in a further throttling mode to linearly and incrementally displace the gate between the open and closed positions said outlet and in order to adjust flow through the outlet.

摘要： A vent valve opens to provide a fluid path from a regulated pressure port to a vent port, a supply valve opens to provide a fluid path from the regulated pressure port to a supply pressure port. A control piston has a linear cam profile with a vent cam that opens the vent valve and a supply cam that opens the supply pressure valve.

摘要： Systems, methods, and apparatuses for a valve assembly are provided. The valve assembly includes an upper sleeve, a lower sleeve, and a poppet. The lower sleeve is coupled to the upper sleeve. The lower sleeve includes a bottom face, a side, a supply port, and a pilot port. The supply port extends through the side of the lower sleeve. The pilot port extends through the bottom face of the lower sleeve. The poppet is operable between a first position and a second position. The poppet is contained between the upper sleeve and the lower sleeve. The poppet includes a first end, a second end, a side, a central cavity, and a hydraulic port. The second end is spaced from the first end, the side is adjacent one of the first end and the second end. The central cavity extends from the first end of the poppet towards the second end of the poppet. The hydraulic port extends from the side of the poppet into the central cavity. The hydraulic port is configured to receive hydraulic fluid at a first flow rate from the supply port and to supply hydraulic fluid to the central cavity at a second flow rate less than the first flow rate.

摘要： A manifold having a first sub-manifold defining a first fluid passage, a second sub-manifold defining a second fluid passage, and a seal-sub occupying an interface between the first and second fluid passage and that seals against the first and second fluid passages to prevent fluid leaks at the interface. The first sub-manifold defines an opening for receiving the seal-sub into the first fluid passage from outside the first sub-manifold that is separate from the interface.

摘要： A normally closed subplate mounted valve has a lower valve seat defining a function port, an upper seat, and a sleeve between the upper seat and the lower seat. The sleeve defines a first port. The poppet is movable within the sleeve to selectively seal against the lower seat in a piloted position or to seal against the upper seat in an offset position. The poppet blocks the first port when the poppet is positioned in an offset position. A piston shaft is affixed to the poppet for moving the poppet into the piloted or offset position. A spring biases the poppet in the offset position for preventing fluid flow into the first port. A pilot port supplies pressure for sliding the piston to compress the spring and to move the poppet away from the offset position to the piloted position so that fluid may flow into a supply port and out of the function port. A second port may be provided in the sleeve. The ports may be selectively configured for supply or vent. Components may be joined with retainer springs. The piston shaft and poppet connector may be a key and key slot engagement. The ports may be shaped for progressive exposure by movement of the poppet. The poppet may be designed to enable pressure assist through the first port when moving the poppet to the piloted position. The valve seats may be provided with angled sealing surfaces that are angularly offset from their mating counterparts.
