1、 simple and practical, chemical bolt fastening connection, flexible and reliable switches.
2、sealing material is EPDM, NBR and other elastic parts, which can avoid any leakage.
3、surrounded by sealing and two-way sealing; leakage is not greater than 5% of the DIN19569 standard requirements.
4、open valve box design; connection between extended rod and rapid joints; suitable for pneumatic, electric, manual and other installation conditions.
5、rising stem design, the stem and the work of the media is completely out of contact.
6、a unique guide and wedge-tight device allows no vibration during the whole process, and can be used as a flow control valve.
7、due to the role of the wedge, the door in the final closing stage and the door frame are pressed tightly, so the operating torque is small.
8、the overall shape of the sealing structure leads to more reliable performance.
9、the wall installation, the valve and the wall are sealed by the EPDM sealing gasket, which is conveniently installed and reliably sealed.
10、compact welding structure, less space required.
11、the valve frame can be connected to the chemical bolts fast.
12、valve has been debugged in the factory, and the installation is simple without grouting twice.
13、removable seat design, which can be online replacement.
