Expansion plug valves are valves that use a plug body with a through hole as the opening and closing parts. Plug body with the valve stem rotation, to achieve opening and closing action. Due to the movement between the sealing surfaces of the plug valve with a wiping effect, and in the fully open can completely prevent contact with the flowing medium, so it can also be used for the medium with suspended particles usually.

  • Features

Dual shut-off and bleed functions are usually achieved by using two separate valves and a spool pipe with a bleed port, which not only takes up a lot of space and weight, but is also expensive to maintain.
Full valve control DEPV integrates DIB functionality in a single valve body with a compact design and few moving parts, resulting in low maintenance, long service life and significantly reduced operating costs for the end user.
Our DEPV operates without any friction or contact between the seal and seat area while maintaining a 100% tight shutoff and bi-directional seal.
Top and bottom access enables online inspection and maintenance without the need for special tools.
Thanks to the backseat design, the stem packing can be updated while the valve is pressurized.
DEPV is non-lubricated.
