摘要:
A bellows valve assembly (11) includes a valve body (13), a bellows housing (39) and a valve actuator (15). The valve body (13) includes an inlet (17), an outlet (19) and a valve seat (29). A valve closure element (25) is engageable with the valve seat (29) to control fluid flow. The valve closure element (25) has a stem (27) that has an upper portion (27b) having an average diameter at least 25 % smaller than the diameter of the lower portion (27a). A pressure balancing bellows assembly (61) divides the bellows housing (39) into a first chamber (69) connected by a passageway (67) to the fluid passage downstream of the seat (29) and a second chamber (55) connected by a passageway (65) to the fluid passage upstream of the valve seat (29).
摘要:
The invention relates to an electrovalve with two hydraulic connections (3, 4), a coil (5) and a guided core (8) in a cylinder (7) of the coil body (6). When the core (8) is moved by magnetizing the coil (5), the electrovalve (1) is opened. When the coil (5) is disconnected, the electrovalve is closed by the force of a spring (27). The core and the valve (1) closing device are pressure relieved due to the fact that the face side of the core (8) has an active surface which corresponds to an active surface (18) on the valve body (14). The elastic main seat seal (20) is located in the housing (2). The pointed main valve seat (13) and the compensating diameter (12) are assembled together and accommodated in a movable seat casing (11).
摘要:
The invention relates to a direct action, pressure-relieved straight valve (1) with a hollow, displaceable sealing tube (19) comprising a valve seat (20) and a valve body (49) with a valve seat seal (21). A drive unit (7) is located outside the medium flow on a side close to the sealing tube (19). A toothed segment (15) on the lengthening lever (14) of the drive unit (7) engages with a toothed segment (18) on the sealing tube (19). The drive unit (7) can be removed from the fluid housing (2) without interrupting the flow of the medium.

A valve (1) for fluids, preferably for gases, comprises an inlet passage (2); an outlet passage (3); a shutter (4) interposed between the inlet passage (2) and the outlet passage (3) and movable between an open position and a closed position; actuating means (26,27). The valve (1) also comprises actuating means (26,27) operatively active on the 5 shutter (4), which comprises an electromagnet (26) and a ferromagnetic element (27) that is movable as a function of the field generated by the electromagnet (26) for displacing the shutter (4) along the movement direction (L). In particular, the actuating means comprises a tubular body (5) made of non-magnetic 10 material in which the ferromagnetic body (27) is inserted.
摘要:
[0037] Embodiments of the present disclosure include a system for controlling a fluid flow. The system includes a valve body (224, 336) including a bore (108) extending along an axis (208, 3134), a stem (210, 316) extending through the bore (108) along the axis (208, 314), and a valve member (206, 310) coupled to the stem (210, 316). The valve member (206, 310) is movable between a closed position (302) where the valve member (206, 310) blocks the flow passage to an open position (306) where the valve member (206, 310) does not block the flow passage. The system also includes a balancing system (202, 308) coupled to the valve member (206, 310), the balancing system (202, 308) comprising a tether (214, 318) and a balance member (218, 320), wherein an opening force unseating the valve member (206, 310) is translated to the balance member (218, 320).
