Correct Installation and Daily Maintenance of Flexible Seat Gate Valve

　　For a long time, water leakage or rust has been common in the general gate valves used in the market. The elastic seat sealing valves produced by our company by introducing European high-tech rubber and valve manufacturing technology overcome the defects of poor sealing and rusting of the general gate valves. The elastic seat sealing valves achieve good sealing effect by compensating the micro-elastic deformation of the elastic gate plates. The valve has a switch. Lightweight, reliable sealing, good elastic memory and long service life.

　　The installation and maintenance of gate valves should pay attention to the following matters:

　　1. Handwheels, handles and transmission mechanisms are not allowed to be lifted and collisions are strictly prohibited.

　　2. Double gate valves should be installed vertically (i.e. the stem is in the vertical position and the handwheel is at the top).

　　3. Gate valves with bypass valves should be opened before opening (in order to balance the pressure difference between inlet and outlet and reduce the opening force).

　　4. Gate valves with belt drive mechanism shall be installed according to the specifications of the product.

　　5. Lubricate the valve at least once a month if it is frequently switched on and off.

　　Elastic seat gate valves have been widely used in various fields such as petroleum, chemical industry, liquefied gas, water supply and drainage, food, pharmaceuticals, power generation, boiler steam system, mineral resources, urban construction, municipal administration, and daily life of residents.
