Features and advantages

Casting body, with sufficient strength to meet the requirements of the working environment, fluid flow will not be hindered.

Elastic wedge, can automatically adapt to the pipe stress caused by the deformation of the valve body.

The welded seat ring is sealed to prevent leakage.

Stem: T – disc – stem connection to prevent stress applied to the side of the stem to ensure smooth operation.

Packing: packing containing preservatives, avoid rust stem. Deep stuffing box ensures long service life of packing.

Seat ring: the valve seat is sealed and welded, which can eliminate the leakage channel and prolong the service life.
