Click For Soft Seal Gate Valves You Don't Know
Soft Seal Gate Valve Overview
The soft seal gate valve is a common type of valve used in water supply and drainage projects, mainly for connecting and cutting off the flow of pipeline media. The soft seal gate valve structure is very simple, consisting of a valve seat, valve bonnets, discs, glands, stems, handwheels, gaskets, and hexagonal bolts.
The soft seal gate valve is coated with electrostatic powder inside and outside the valve body and baked in a high-temperature oven, which ensures the smoothness of the entire path and the wedge-type groove inside the gate valve. The appearance also leaves aiming impressions on viewers.
The soft seal gate valve is normally blue when used in general water pipelines, and red when used in fire fighting pipelines.
Use of soft seal gate valves
Soft seal gate valves are mainly used in waterworks, sewage pipes, municipal drainage projects, fire fighting pipeline projects, and industrial pipelines. We are also able to customize according to the site use, such as open stem soft seal gate valves, concealed stem soft seal gate valves, extended stem soft seal gate valves, buried soft seal gate valves, electric soft seal gate valves, pneumatic soft seal gate valves, etc.
1. Soft seal gate valves overall are adopted ductile iron QT450. The cost will be much more affordable than the cost of cast steel, stainless steel. For engineering bulk purchase, it is quite affordable and guaranteed in terms of quality.
2. The construction design of the soft seal gate valve is simple, easy to disassemble. After long-term use of the soft seal gate valve, its resilient gate will lose elasticity because of frequent switching, resulting in poorly sealing performance and valve leakage. At this point, the advantages of the structure design come out. It allows maintenance personnel to directly disassemble and replace the gate in-situ, without taking down the entire valve. This will save your time and effort, manpower and material resources.
