The main features of the products as follows:
1, the valve has good appearance and a smooth channel lines that reduce flow resistance coefficient. So they are energy-saving products.
2, the valve seal used bellows seal and graphite + stainless steel , reliable sealing, do not have to change packing when long-term use . Valve leakage has obvious damage : high temperature, highly toxic, inflammable, explosive, radioactive leakage media not only pollute the environment, but also often cause significant personal and financial losses legislation. The sealed structure of our products can effectively solve the problem of leakage, so called green products abroad.
3, the valve design  manufacturing standards is in accordance with the advanced Germany standards strictly, the inspection test is in accordance with the standard DIN3230 strictly.
4, the valve has  small torque so reduce labor intensity, and can take any form of device drivers, so convenient for remote control.
