A drain valve for a sterile container includes: a valve housing; a bypass that connects a container gas volume with an external gas volume; a valve body that blocks the bypass; and an actuator that displaces the valve body between a passage position and a blocking position. The valve body is displaceable according to a temperature and/or a pressure of the bypass gas volume. The valve housing has: at least one holding web, at least part of which can be located in a holding bracket of the valve receptacle; and a closure. The valve housing is pivotable from an open position into an installation position in which the closure can be fixed to a closure receptacle. When the valve housing is transferred into the installation position, the valve body is transferred into the blocking position and subjected to a closure force.

The cooling water temperature control device includes a thermo valve 2 that opens a main flow passage R1 when the temperature of a sensed region R1a in the main flow passage R1 reaches or exceeds an operating temperature set in advance, a sub-valve 3 that opens and closes a sub-flow passage R2 bypassing the thermo valve 2, and a control unit 6 that opens the sub-valve 3 when the temperature of the cooling water on an upstream side of the thermo valve 2 is a predetermined temperature. One end on the upstream side of the sub-flow passage R2 is connected to the sensed region R1a in the main flow passage R1 or to a downstream side of the sensed region R1a, and the operating temperature of the thermo valve 2 is set to be equal to or lower than the predetermined temperature.

Provided is a downsizable valve unit. A valve unit 1 includes a valve case 4 including a valve case main body 4A where a thermo valve 2 is housed and a valve seat 4Aa which a valve body 2b unseats from and seats on is formed, and a sleeve 4B formed protruding outward from the valve case main body 4A; a sub-flow path R2 formed to include a cooling water storage chamber S formed inside the sleeve 4B, a lead-out passage 4Ae communicating the upstream side of the valve seat 4Aa in the valve case main body 4A with the cooling water storage chamber S, and a lead-in passage 4Af communicating the downstream side of the valve seat 4Aa in the valve case main body 4A with the cooling water storage chamber S; and a sub-valve 3 attached to a sleeve 4B to open and close a sub-flow path R2.

A heat exchanger is configured to adjust a flow restriction of flow passages through the heat exchanger in response to changes in temperature of elements that define at least a portion of the flow passages. The elements include a first material having a first coefficient of thermal expansion, and a second material having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion.

An activation assembly for a sealed container includes a striker, a detent, and a shape memory alloy (SMA) wire connected to the detent. The SMA wire may move the detent from a first position to a second position relative to the striker based on activation of the SMA wire where, in the first position, the detent is engaged with the striker, and, in the second position, the detent is disengaged from the striker and the striker is movable from a stowed position to a deployed position.

A passive tube closure valve comprising an elongated body extending along a first axis made of a shape memory alloy with a threshold contraction along the first axis at a threshold temperature. The closure valve further comprises a passageway extending along a second axis different from the first axis shaped to surround a conduit line extending along the second axis. The closure valve further includes a first modifying structure on a first portion of the passageway and a second modifying structure on a second portion of the passageway opposite the first modifying structure. Contraction of the elongated body can cause the first modifying structure and the second modifying structure to move towards each other; where movement of at least one of the first modifying structure or the second modifying structures can be configured to modify the conduit line.

A valve including: a body having: a first aperture; a second aperture; a first channel in fluid communication with the first aperture; a second channel in fluid communication with at least part of the second aperture; and an outlet aperture; an adjusting portion associated with the body, the adjusting portion providing a stop; a piston in fluid communication with the first channel, the second channel and the outlet aperture; a thermostatic element configured to assist with moving the piston in response to engaging with the stop, the piston being configured to regulate fluid flow from the first channel and the second channel to the outlet; and a return spring configured to assist with biasing the thermostatic element, wherein part of the fluid flow entering the first channel flows along the piston and exits from a portion of the second aperture.

A passive thermal control valve comprising a thermal actuator coupled to a valve body having first and second ports. The thermal actuator including an actuator body having an inner bore. An adjustment stop engages the actuator body. A cylinder is received within the actuator body inner bore and the cylinder has a cylinder bore open at one end. An actuator spring within the actuator body biases the cylinder towards the adjustment stop. An actuator rod is at least partially received within the cylinder and has first and second ends. At least a portion of the actuator rod is allowed to extend through the open cylinder bore. A sealing element forms a seal between the actuator rod and the cylinder and defines a sealed chamber within the cylinder. A thermal fluid is contained within the cylinder. A lever mechanism is connected to the valve body and includes a lever having a first end connected to the valve body. A valve spool is connected to a lever second end. The valve spool is arranged and designed to close the first port and allow a system fluid to flow through the second port, close the second port and allow the system fluid to flow through the first port, or allow the system fluid to flow through both the first and second ports.

A deaeration valve includes a housing and a ball in fluid communication with housing. The ball can include a body, a seat defining a bleed passage therein, and a deaeration pin slidably disposed within the bleed passage.
