Seat, sealing completely made of metal materials, and surface hardening treatment, even if the opening and closing is frequent, can still maintain a high sealing performance of the valve, put an end to the multi-layer sealing structure not scour resistance and other shortcomings, greatly improve the service life of the valve;
2. Rely on torque seal
Valve throughout can keep superior two-way sealing performance and valve sealing force does not rely on media, completely provided by the drive torque seal, valve can reliable sealing under high and low pressure. The sealing performance test results are in accordance with the standards of API 609 and ISO5208.
3. The seat/sealing ring can be replaced on site
Replaceable seat/sealing ring design to facilitate valve site maintenance;
4. High performance of packing seal
The combined packing sealing system is adopted to ensure the maximum leakage rate of valve is less than 20ppm. The movable seal structure can be used to keep the stuffing durable and prolong the packing period.
