1.Adopt elastic FTEE as dynamical saline seif-cmpensating filling, which possrss self-sealing performance.
2. Large diameter seal ring or back seal structure can ansure the safety and reliability of dynamical sealing.
3. Equipped with dustproof ring of valve handle in order to protect the interior parts of valve from erosion of exterior arvironmart.
4. The valve body adopts barrel stnrcture and possesses high intensity and beautiful appeararue. The sealed auxiliary adopts the fireproof structure.
5. Non-forcible dynamical sealing stnchue posers small open and close torque. The handwheel can be smoothly operated.
1.The valve is specially d紐,med for the pipeline or equipment of petroleum and liquefied gas.
2.The sealed auxiliary adopts nylon 1010 stainless steel. The sealing is reliable. Reliable upper sealing equipment can strictly protect the filling and absolutely avoid the leakage.
3.Adopts the fireproof structure.Even if the soft sealing material is burned,the metal seal still takes effect.
