Main features: It uses a self-lubricating liner embedded in the valve body, and the liner is pressed in under pressure to prevent leakage between the liner and the valve body. There is no need to inject sealing grease that will contaminate the medium during use, and it flows in both directions. Widely used in oilfield extraction, transportation, and refining equipment, as well as in the petrochemical, chemical, coal gas, natural gas, liquefied petroleum gas, HVAC industries, and general industries.
