Drawings and dimensions: 

Features:

1.Soft seal, gate plastic bag, corrosion-resistant;

2.Not easily broken, long service life;

3.For tap water, sewage, construction, electricity, medicine, metallurgy, textile, energy systems and other fluid lines

4.Fluid resistance is small, medium flows through the gate valve does not change its flow direction, so the fluid resistance is small. The company is located in:

5.Opening and closing torque is small, more open and close effort, because the gate valve opening and closing direction of flow and medium flow perpendicular to the valve, compared with the closing valve, gate valve opening and closing more effort.

6.Media flow direction is not limited, no spoiler, not reducing pressure, the medium can flow from either side of the gate valve in any direction

7.The length of the structure is shorter because the gate of the gate valve is placed vertically in the valve body and the stop valve flap is placed horizontally inside the valve body so that the length of the structure is shorter than the stop valve. The company is located in:

8.Sealing performance, fully open when the sealing surface erosion by smaller. The company is located in:

9.Full open, the sealing surface by the erosion of the working medium smaller than the stop valve. The company is located in:

10.Simple shape, casting technology is better, a wide range of applications.
