Abstract: In the embodiment, a steam valve device has, a steam regulating valve, and an intermediate flow path connecting the main steam stop valve and the steam regulating valve. The main steam stop valve and the steam regulating valve respectively have: casings where flow paths are formed between horizontal inlet ports and outlet ports opened downward and valve seats are arranged in the flow paths; valve elements movable up and down in the casings; and valve rods for driving the valve elements. The valve rods extend upward, and they are pulled off upward in a direction to outside of the casings when opening the flow paths. The intermediate flow path changes the flow direction of main steam flowing out of the outlet port of the main steam stop valve from downward direction to horizontal direction to guide the main steam toward the outlet ports of the steam regulating valves.

Abstract: A throttling valve assembly has an outer housing that is sealed. An actuator is connected to a pressure balanced shaft that extends into the housing to operate a plurality of linkages that can rotate blades in tandem. With the surrounding housing sealed, the shaft penetrations of the blade support shafts no longer need seals or a purge system to supply process gas during times of reduced pressure in situations with the blades nearly closed. A pressure equalization system has balance passages internal to the housing to allow flow from higher pressure zones to lower pressure zone of the process gas so as to avoid creation of a condition that can draw air into any zones of reduced pressure in the housing.

Abstract: A valve with an integral means for bleeding internal pressure prior to separation of a bonnet for the valve from its engagement with the valve body, provided by a bore through the valve body. This allows the internal pressure of the valve to equalize with atmospheric pressure prior to complete disassembly of the bonnet from the valve body. The bore through the valve body also serves as a leak detector, by providing a path for fluids passing through the valve to leak to the exterior of the valve body in the event of a failure of the seal between the bonnet and the valve body, which can readily be detected by passersby upon inspection of the exposed end of the bore at the exterior of the valve body.

Abstract: An unloader includes a first volume bottle with a cavity formed therein of predetermined volume, and a port in the forward end with a plug operably mounted to selectively open and close the port. A second volume bottle is stacked on the first volume bottle and has a port in the forward end with a plug operable to open and close the second bottle port. The second bottle is arranged such that the second port will fluidly connect the first and second bottles. Actuators are connected to the plugs in the first and second bottles to selectively open only the first bottle or both bottles together, to thereby provide a two stage internal clearance for the reciprocating compressor cylinder.

Abstract: A main valve mechanism for opening and closing a main flow path between a first port and a second port has a main valve body, a large-diameter first piston for opening the main valve body, a main pressure operating chamber for driving the first piston, and first spring means for closing the first piston. An auxiliary valve mechanism for opening and closing an auxiliary flow path has an auxiliary valve body, a small-diameter second piston for opening the auxiliary valve body, an auxiliary pressure operating chamber for driving the second piston, and second spring means for closing the second piston. The main pressure operating chamber and the auxiliary pressure operating chamber are connected to each other through a connecting hole. There are such relationships between piston diameters of both the pistons and repulsing forces of both the spring means that the second piston is actuated by lower fluid pressure than the first piston.
