In addition to the advantages of elastic seat seal gate valve, German standard soft seal gate valve can be more intuitive valve opening, opening and closing quickly and reliably. Therefore, it is often used in fire and industrial systems, and is generally installed at a higher position from the ground.
German standard soft seal gate valve overcomes the defects of poor sealing, elastic fatigue and easy rusting. German standard soft seal gate valve is the replacement product of traditional gate valve. It can achieve good sealing effect by using the compensation function of slight deformation of elastic gate valve. German standard soft seal gate valve has the advantages of light switch, reliable sealing, good elastic memory and long service life.
German standard soft seal gate valve parts material:
1. Valve body: ggg50;
2. Disc: ggg50 + EPDM, ggg50 + NBR;
3. Disc nut: brass;
4. Stem: AISI 420;
5. Gasket: EPDM / NBR;
6. Valve cover: ggg50;
German standard soft seal gate valve can be widely used in water, sewage, construction, food, electricity, medicine, metallurgy, light textile, energy system and other fluid pipelines as regulating and intercepting devices.
