Issues that should be noted for forged steel check valves

Forged steel valves often overlook the issue of grease injection. After refueling the grease gun, the operator selects the valve and grease connection method for the low-temperature shut-off valve before proceeding with the grease injection operation. There are two types of forged steel gate valves: on the one hand, the amount of grease injected is insufficient, and the sealing surface is accelerated due to a lack of lubricant. On the other hand, excessive fat injection can cause waste. The reason is that there is no precise calculation of the sealing capacity of different valves based on their type and category. The sealing capacity can be calculated based on the size and type of the valve, and an appropriate amount of lubricating grease can be injected reasonably.
