Where do gate valves in PE fittings leak

Gate valves

Most gate valves leak from the gate valve gasket. This is due to the accumulation of sediment on the seal, the seal has a little displacement.

All that is needed to prevent leakage on the gate valve gland is to tighten the gland nut. Another cause of leakage is likely to be the main valve connected to the valve body, which can be unscrewed. Thread upper ring with raw material belt for spare; Place a new fiber washer on the support to secure the area. The third place where the leak occurred was in the nut and spindle area.

What caused the gate valve to break

The reason for the gate valve rupture is that the pressure to close the gate valve is too high due to its fragile nature. The spindle thread does not go deep into the valve, so if too much pressure is applied there is not enough position to prevent external resistance. Tianjin gate valves

Why is the gate valve stuck

The gate valve is stuck because iron and scale deposits accumulate in the water passing through the main pipe, along with other circulating deposits, including hot and cold water systems. All sediments tend to stick to rough areas more easily than rough areas, while flat areas tend to be valves. Sediment enters a mechanism that causes a moving part to block rather than move smoothly.
