The present invention relates to a valve assembly for blowing or draw-blowing preforms made of polymer material, applicable to a machine suitable to transform said preforms into bottles or containers.

In particular, the invention relates to a valve assembly (1) comprising a control block (2) and a blowing block (3), in which the blowing block (3) comprises an outer body (50) having a longitudinal axis, inside which a blowing cylinder ending at the bottom with a nozzle (58) suitable to be coupled with the neck of a container (C), is slidingly accommodated, and wherein the control block (2) receives pressurized air from at least one pressurized air source and sends it to said blowing block (3) according to a predetermined pressure profile dependent on the selected blowing cycle, in which the control block (2) comprises a plurality of valves for dispensing pressurized air at different pressures, and an air exhaust valve, characterized in that said valves are driven by pressurized air at a pressure between 15 and 40 bar.

A plastic valve for preventing distortion is disclosed. The plastic valve comprises a connection member made up of plastic, a case member formed on an outer surface of the connection member, and a flange member made up of plastic and formed at an end part of the connection member. A pipe is connected by being inserted into a hole of a central part of the connection member and a distortion prevention member for minimizing a force corresponding to distortion applied in a direction opposed to a direction of the connection is formed in the flange member. The connection member is made up of fluoride resin and the case member is made up of engineering plastic.

A stop assembly includes a top plate and a stem. The top plate is configured to seat onto the stem. The stem is configured to rotate within grooves of the top plate so as to open and close a valve. The stem has a lower surface and an upper surface and includes a mating aperture through the central body extending above the upper surface. It also has a pair of tabs protruding from the upper surface adjacent the mating aperture. The mating surface and the pair of tabs divide the upper surface to form opposing ledges partially around a perimeter of the central body. The top plate has a central aperture and a pair of opposing grooves that create a pair of stops. The stops are configured to rest adjacent the opposing ledges, such that rotation of the stem contacts the pair of stops against the pair of tabs.

Disclosed is a server rack system within an enclosed building and a process for directing air through a server facility. Air is channeled within a server rack assembly and then through a closed loop back again into the server rack assembly. Impediments may control the degree of airflow availability.

A coolant control valve is provided that includes at least one actuator, a first rotary valve body and a second rotary valve body, each rotary valve body driveably connected to the at least one actuator. The second rotary valve body is arranged non-coaxially to the first rotary valve body.

A valve having a flow trim assembly that can be quickly and efficiently removed and repaired or replaced. A body section having a central through bore that defines an inlet, an inner chamber or space, and two selectable outlets. Further the selectable outlets can direct flow in either a 90 degree “angle” orientation or at straight “in-line” orientation. An actuator stem extends into the inner chamber. A first (movable) trim member is attached to the rotator, and can be selectively rotated relative to a second (fixed) trim member. The first and second trim members cooperate to adjust flow opening through the valve. A valve bonnet that allows direct coupling of an actuator to the valve.

A plastic faucet body and a die for molding the same are disclosed in present invention. The plastic faucet body comprises a left water inlet pipe and a right water inlet pipe, where a connecting cross-beam is disposed between the left water inlet pipe and the right water inlet pipe, the left water inlet pipe and the right water inlet pipe are embedded with a threaded copper pipe, respectively, the copper pipes are formed integrally with the plastic faucet body by means of a single stage process and are in communication with the corresponding left water inlet pipe and the right water inlet pipe, respectively.

A modular valve assembly is formed from multiple modular valves having a valve base and a valve actuator. Each base includes at least a first channel and a second channel and an internal passage forming an opening in the first channel so as to be in selective fluid communication with an exterior port of the valve base, and with the second channel being a through passage that is not in fluid communication with the internal passage. Adjacent valve bases are interconnectable in one of two orientations either with the first and second channels of one valve base being aligned with the first and second channels, respectively, of an adjacent valve base, or with the first and second channels of one valve base being aligned with the second and first channels, respectively, of an adjacent valve base. The valve bases may be provided with third and fourth channels for three-way operability.
