Product Details

NSV Y-type globe valve is the most widely used valve. The reason why it is so popular is that it has little friction between sealing surfaces in the process of opening and closing, and it is more durable. The opening height is not too high. Its closing principle is that, depending on the pressure of the valve stem, the sealing surface of the valve disc and the sealing surface of the valve seat closely fit together to prevent the flow of medium. The globe valve only allows unidirectional flow of medium and has directivity when installed. The structure length of globe valve is larger than gate valve, and the fluid resistance is large.

STRUCTURAL FEATURES

◎Seat
For carbon steel globe valve, the seat is usually forged steel. The sealing surface of the seat is spray welded with hard alloy specified by the customer. Renewable threaded seat is used for NPS≤10 globe valve and welded on seat can be also optional if being requested by the customer. Welded on seat is used for NPS ≥ 12 carbon steel globe valves. For stainless steel globe valve, integral seat is usually adopted, or to weld hard alloy directly integrally. Threaded or welded on seat is also optional for stainless steel globe valve if being requested by the customer

.

◎ Stem Nut

Usually, the stem nut is copper alloy. It is also can be made of ASTM A439 D2 if being requested by the customer. For large sized globe valve, rolling bearing is fitted at the two sides of stem nut in order to minimize the open and close torque of the globe valve.

◎ Stem Design

The stem is of integral forged design. The minimum diameter of the stem shall per the standard requirement.
