1.wedge type GATE VALVE has small flow resistance.

2 when the open-close direction and medium flow wedge movement direction perpendicular, thus on-off is more economical.

3 The volume is large, so the installation space is required to be large.
4 the wedge type gate valve threads in the external transmission, lubrication and fluid corrosion. Therefore according to the movement direction of the stem and intuitive judgment of valves open position, not by accident caused by running ones.
5 this series of valves with manual device in the match, pneumatic device or electric equipment form of manual valves, pneumatic valves and electric gate three categories of products.

6.In the opening state, the guide slot of gate valve is stored easily by impurities, resulting in that the gate valve cann't be cut off strictly while closing the valve.

7. GATE VALVES have short service life.
