摘要： A valve mounting arrangement comprises a mounting member (27) for fixing to valve actuator (12) and a rotatable part (25). The rotatable part is, or is connected to, a directional fluid control valve for controlling the supply of fluid the actuator. The mounting member (27) has first and second ports (41,42) for communication with corresponding ports on the actuator. The control valve has at least one first fluid passage for the supply of fluid to the actuator and at least one second fluid passage for the exhaust of fluid from the actuator. The control valve is rotatably coupled to the mounting member for rotation about a rotational axis such that the first and second fluid passages are in fluid communication with the first and second ports of the mounting member irrespective of the rotational position of the directional control valve body relative to the mounting. A clamping member (28) clamps the rotatable part against rotation at a selected position.

摘要： An assembly comprising a first fluid flow control device (27) coupled to a second fluid flow control device (25). The first fluid flow control device has a body with a first fluid passage and the second fluid flow control device has a body with a second fluid passage, the first and second fluid passages being in fluid communication to form a first fluid path. The first and second fluid flow control devices are coupled together by means of a rotary coupling comprising a first coupling part and a second coupling part defining mutually co-operating guide surfaces for supporting relative rotation of the first and second fluid flow control devices. The first coupling part (56) is provided by the first fluid control device is penetrated by at least part of the first fluid passage. The second coupling part connected to one of the first and second fluid flow control devices and comprises a releasable clamping member (28) for movement between a first position in which the first and second fluid flow control devices are rotatable relative to one another about a rotational axis and a second position in which it clamps against a clamping surface of the other of the first and second fluid flow control devices so as to clamp the devices against relative rotation in at least one selected position.

摘要： A flow control device (120) comprises a body (122) having first and second fluid ports (41) between which fluid may flow, the direction being dependent on the pressures at the respective ports. First and second valve seats (147) associated with the first and second fluid ports are spaced apart in the body to define a clearance between them. A fluid pressure actuated floating valve member (155) in the clearance is arranged to travel in a direction towards the first valve seat and away from the second valve seat and in the opposite direction, depending on the prevailing fluid pressures. At least one stop (158,159) limits the travel of the valve member towards the first or second valve seat. At least one of the first and second valve seats is adjustable to vary its position
