Electrostatically-Controlled, Self-Pneumatically-Actuated Microvalve with High Pressure Tolerance and Low Pressure Loss This paper describes a microvalve to control liquefied gas in a micro fuel reforming system. To realize both high pressure leak tolerance and low pressure ... D Satoh,S Tanaka,M ...
As shown especially inFIG. 1A, each one of the pneumatically actuated or operated components10A to1OH,11A to11H,12A to12H and13A to13H further includes or is respectively associated with and connected to an allocated control valve, in order to control the supply of pressurized air to the ...
The valve consists of a pneumatically actuated piston actuator, a stainless steel housing and a bellows element. This bellows element serves primarily as a seat seal, but also to hermetically seal of the media chamber. Due to the comparatively short stroke, these valves achieve a very high numbe...
The externally piloted angle seat valve is operated with a single or double-acting piston actuator. The actuator is available in two different materials, depending on the ambient temperature. High flow rates are attained with the virtually straight flow
Adjustable pressure reducer and foot-controlled flow rate valve are positioned in flexible pipe. Union is oriented axially of casing. Parts of injector are made from elastic deformation plastic. Method involves using similar disposable medical syringe as blank. EFFECT: increased efficiency and reduced ...
It is therefore a primary object of the present invention to provide an actuating system for a valve which system may be actuated mechanically and pneumatically. Another object of the present invention is to provide two different modes for effecting mechanical actuation of a valve. ...
