Abstract: The present invention relates to industrial gate type sealing valves for low and high pressure. In particular, the present invention relates to a sealing assembly and to a gate valve comprising such an improved sealing assembly. The sealing assembly ensures excellent sealing performance at low and high pressures by exclusively using thermoplastic material sealing elements, completely eliminating the drawbacks which afflict the sealing systems of known type, in particular in relation to the reliability of the sealing elements made of elastomeric material. The sealing assembly comprises one seat (30) insertable in said valve body and defining an axial cavity (6) for the passage of a pressurized fluid, said seat defines a main housing at a front surface (30A), a first sealing element (3), made of thermoplastic material, being accommodated with interference in a first portion of said main housing, a second sealing element (4), made of thermoplastic material, which is accommodated within a second portion of said main housing axially delimited by a closed bottom surface (52) and radially delimited between a outermost surface of said main housing and said first sealing element, wherein said second element is accommodated with radial clearance in said second housing portion to be floating, with respect to said seat, along a direction parallel to said central axis when said seat is installed in said valve body and when said seat is internally crossed by said pressurized fluid.

Abstract: The present invention relates to sealing valves used in the petroleum and gas extraction industry, in particular but not exclusively, to medium- or high-pressure ball valves. In particular, the present invention relates to a sealing assembly (101, 102) for ball valves (1), and to a ball valve comprising such an improved sealing assembly. The sealing assembly ensures excellent sealing performance at low and high pressures by exclusively using a thermoplastic material sealing element (31), thus completely eliminating the drawbacks which afflict the sealing system of known type, in particular in relation to the reliability of the sealing elements made of elastomeric material.
