GTL-Z41W Stainless Steel Gate Valve

Gate valve is the most widely used valve. It controls the opening and closing of the valve through the lift of the gate. The gate is perpendicular to the direction of the fluid, and the size of the channel can be changed by changing the relative position between the gate and the valve seat.

Application specification:

1.Design and manufacture according to GB12234-89

2. Structure length according to GB12221-89

3. Flange size according to JB/T79-94

4. Valve inspection and test according to GB13927
