Operating principle
The valve is hydraulically operated, piston actuated type. This valve is studied to prevent throttling noise reduction. It reduces an higher inlet pressure to a lower downstream pressure at a fixed ratio. The valve is simple to maintain due to the minimal external accessories, built in check feature. The valve permit easily serial pressure – reduction.
Additional features
– pressure sustaining, the valve maintain a minimal inlet pressure;
– main valve totally open when the inlet pressure rich a minimal and adjustable value.
