Casting steel gate valve stem selection is the key

Selecting a cast steel gate valve and selecting the stem is very important. Why? How can you tell which stem is good? The stem is just a part of the gate valve. Why is it so important?

Cast steel gate valve stem is a material difference between the two, the small accessories have now been many manufacturers as a "fudge" place, in order to maximize their own interests, or to a customer, the price, it is usually, valve is 304, but the stem is 321 or worse, other buyers also seldom go to care about the small accessories, it also has caused many wussy cast steel gate valves of the boss, how also think impassability, why you do a valve 304 to 28 block, can sell some manufacturers to $26. If not too much, these are small sales techniques, but hopefully don't disrupt the entire valve market.

In the casting steel gate valve manufacturers, integrity first.
