German Standard DN100 F4 Copper Gland Gate Valve Copper Lock Nut Z45X Resilient Seat Seal Soft Seal Gate Valve

product description

When the elastic seat gate valve is closed, the sealing surface can be sealed only by the medium pressure, that is, the sealing surface of the gate plate is pressed against the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forced to seal, that is, when the gate valve is closed, the gate plate must be forced to the valve seat by external force to ensure the tightness of the sealing surface.
When the gate valve is opened, when the lift height of the gate is equal to 1:1 times the diameter of the gate valve, the fluid channel is completely unblocked, but this position cannot be monitored during operation. In actual use, the apex of the valve stem is used as a sign, that is, the position where it cannot be opened, as its fully open position. In order to take into account the lock-up phenomenon due to temperature changes, it is usually opened to the top position, and then back to 1/2-1 turn, as the position of the fully open gate valve. Therefore, the fully open position of the gate valve is determined according to the position of the gate (ie, the stroke). The sealing surface is easy to wear, which affects the service life. When opening and closing, the two sealing surfaces of the gate and the valve seat rub against each other and slide, and the medium pressure is required. It is easy to cause abrasion and wear, affecting the sealing performance and shortening the service life.
For a long time, the general gate valves used in the market generally have the phenomenon of water leakage or rust, which overcomes the defects of poor sealing and rusting of general gate valves. It has obvious advantages such as light switch, reliable sealing, good elastic memory and service life. It can be widely used in tap water, sewage, construction, petroleum, chemical industry, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system and other pipelines as regulation and interception devices. This is the benefit and advantage of a resilient seated gate valve
