Features

• The special structure design of the valve cage type and its own patented multi-stage buck labyrinth disc ensures the flushing and wear of the small opening moment and the air exhaust when the opening is fast.

• The core has cage guidance, good stability and low noise. The valve flap has a double throttle piece, which can effectively protect the sealing surface and greatly extend the service life.

• The valve trim is made of high-quality materials, hardened on the surface and has a long service life.

• There is a balance hole on the valve flap to reduce the unbalanced force. The drive unit is light and easy to operate.

• Imported GARLOK packing, good sealing performance, low friction coefficient, no damage to the valve stem.

• Sealed surface overlaid with hard alloy, which is resistant to abrasion and corrosion and is resistant to erosion.

• The modular design of the trim allows quick disassembly and replacement of trim on site, eliminating the need for cutting and welding valves, facilitating maintenance and reducing maintenance costs.
