1.Tight Internal Leakage Seal: internal leakage meets the requirements of API 598 bidirectional sealing; the valve is not restricted by on-site installation conditions and can be installed in any direction.
2.Reliable External Leakage Seal: External leakage meets the requirements of ISO 15848 and TA-LUFT, and can be used in toxic and harmful media conditions.
3.Rapid Opening and Closing: The valve has a 1/4 switch characteristic and has fast response and tight shutoff functions.
4.Anti-static Design: The valve body, ball, valve stem and other metal parts of the valve are in close contact to form a complete electrostatic conduction circuit, so that the static electricity generated in various parts can be discharged in time, avoiding the risk of failure caused by local static electricity concentration.
5.Fireproof Structure Design: With a unique fireproof structure, even if the soft sealing valve seat is burned due to fire inside the pipeline, the ball is in close contact with the metal structure, which can still prevent the fire from spreading further.
6.Anti-blowout Stem Design: The valve stem structure adopts an anti-flying step design. Even if the packing gland is loosened, the valve stem will not fly out due to internal pressure and cause a safety accident.
7.Dynamic Packing Loading Design: provides continuous preload for packing, compensating for fluctuations in pressure and temperature and wear of packing.
8.Diversified Operation Modes: The valve adopts a universal design and can be adapted to various types of actuators such as manual, start-up, electric, and hydraulic according to requirements.
9.Others: Structural design such as central cavity relief, insulation jacket, diameter reduction, etc.
