Features

• The construction of the slanted stem and the optimum flow path form the medium flowing in a nearly straight line with a high Cv value and low head loss.

• The valve-guided valve flap of the valve body has an upper and lower guide ring, and the top and bottom of the valve flap are simultaneously guided to form a piston valve flap in the middle of the valve body, which can eliminate the jam caused by various force conditions. , surface scratches, flap tremors and other phenomena. The guide ring at the bottom of the disc allows fluid to pass in a nearly straight line, effectively eliminating valve failure caused by side impact.

• The valve sealing surface is made of hard alloy or solid carbide. It has excellent comprehensive mechanical properties, wear resistance and erosion resistance, and can maintain the long service life of the valve.

• Garlock Inside uses Garlock high-temperature packing to ensure optimum sealing and lubrication, making it easy to operate safely.

• The main body of the valve is welded with a special processing to weld the hard alloy sealing surface. The structure is compact, and the tapered sealing design reduces the axial force and provides a reliable and durable sealing.

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