Forged steel ball valve is the preferred valve of gas pipeline, gas pipeline forged steel ball valve is forged steel structure, especially for gas, natural gas, acid gas, water, oil and coal slurry and other media conditions, suitable for Class150 ~ Class1500, on pipeline various conditions of oil, chemical, fire station, play a role of cutting off and turning on the media. Become forged steel ball valve materials are also carefully choose.
Ball valve used fixed structure, floating seat, under a pressure can be achieved less torque, using a self-lubricating PTFE metal sleeve, and high-strength, high-quality finish to fit the stem, the coefficient of friction to a minimum.
Forged pipeline valve use a polymer material as seat seal, sealing seat used a spring-loaded, with excellent sealing performance in a wide range of temperature changes and pressure changes, ensure no bubbles leaking seal.
