High pressure valve with ball closure - has long external lever arm permitting opening under low operating force
摘要
<p>The high pressure valve closure in a housing has an external actuator to lift the closure from the seat. Between the actuator lever and closure (29) are arranged a number of transmission elements within the valve housing. The closure element is a spring loaded ball, lifted from its seat by actuating an external lever (60) via a pivoting shaft (53) and internal actuating shorter lever (59). This lever may actuate the ball via a plunger.</p>
