Abstract: A bi-directional relief valve includes a cage (12) including a bore (32), a spool (14) located in the bore (32), and biasing means urging the spool towards a closed position. The cage further includes a first inlet/outlet port (50) and a second inlet/outlet port (52). Each port is connected with the bore. The bore includes a central section (38) having a first diameter and a reduced diameter section (42) having a second diameter, which is smaller than the first diameter. The spool is movable with respect to the cage within the bore. The spool includes a smaller diameter section (60) received in the reduced diameter section (42) of the bore and a larger diameter section (62) received within the central section (38) of the bore. The spool includes a passage (70) open to the first port (50) and a radial aperture (90) extending through the spool from the passage. The biasing means urges the spool towards the closed position where fluid flow is blocked through the radial aperture between the passage and the second port. When the biasing force of the biasing means is overcome, the spool moves toward an open position where the smaller diameter section of the spool moves toward the central section of the bore such that fluid flow is no longer blocked through the radial aperture between the passage and the second port.

Abstract: The invention relates to valves and particularly, though not exclusively, to gate valves. There is provided a valve comprising a housing (1) and a valve member (2) moveable within the housing (1) to open and close the valve. In a first aspect the valve is provided with means to reduce friction between the housing (1) and valve member (2). In a second aspect the valve is provided with an operating member (20) which is associated with the valve member (2) and passes through an aperture (21) in the housing (1) which is sealed when the valve is in the open position. Such a valve addresses difficulties relating to the operation of prior art valves, particularly gate valves, and specifically the difficulties created by frictional drag upon movement of the valve member, and difficulties in maintaining the valve.

Abstract: The invention relates to a shut-off valve (17) for shutting off large-diameter ducts. Said valve comprises a housing (1), a shut-off element (19) with a ring (3) and a shut-off disk (2) which are joined together, as well as two housing seats (21) assigned to the shut-off element (19). The aim of the invention is to improve the shut-off disk such that with reduced effort a uniform sealing action is obtained which is independent of the peripheral position at the shut-off element. To this end the invention provides for the two housing seats (21) of the housing (1) to have no contact with the ring (3) or shut-off disk (2) in any operating position, for the distance between the two housing seats (21) and the ring (3) or shut-off disk (2) to remain substantially constant and for it to be possible for an annular gap present between the two housing seats (21) and the ring (3) or the shut-off disk (2) to be filled with an expandable seal (5) which is arranged especially in the housing seats (21).
