A piston regulated pressure reducing valve
A piston regulator of a type that seals on the low-pressure side of a valve seat (10) includes a mechanism by which the valve can be shut off, for example for transport or storage, without risk of overloading the seat (10). Two exemplary mechanisms are disclosed. The first involves applying a closin...

| description | A piston regulator of a type that seals on the low-pressure side of a valve seat (10) includes a mechanism by which the valve can be shut off, for example for transport or storage, without risk of overloading the seat (10). Two exemplary mechanisms are disclosed. The first involves applying a closing load to a regulating piston (6) via a closing piston (17) with a surface that is acted on by secondary pressure to press it away from the regulating piston (6). The second arrangement is based on a nested regulating element: an inner sealing element (901) and outer slidable casing (900) are separable when a closing force is applied. This allows the casing (900) to transfer forces arising from secondary pressure and excessive closing force; the sealing element (901) is pressed onto the seat through a load supplied by a closing spring (903). In both cases, the load on the seat is limited. The nested regulating element can additionally be loaded by an adjustment spring or similar to provide a variable-pressure regulated output. |
