◆With a fast-detachable structure, seat adopts threadless design, with convenient disassembly
and assembly.On-line examine and repair can be carried out after opening the bonnet.
◆For the same diameter, the trims with several Cv can be exchanged to settle for expansion of
production capacity and to realize an accuracy control of flow reduction.
◆High-strength integral valve plug stem can never drop off, bend and anti-rotation and be ease on
even control of turbulent flow under the conditions of high temperature and differential pressure.
◆Inherent flow characteristics such as equal percentage and linear are defined as per different
designs of type of seat.
◆Snap-in self-sealed seat, can be automatic centering, no need of grinding, and closely shut off.
◆All-metal plug seat adopts a special-designed angle to ensure a bidirectional linear sealing and
realize a close shutoff.
◆The seal seat, designed for double-protecting and metal-inserted with long service life, no worry
about erosion and blockage of granule medium.
