Summary. What is WJ341H-16C globe valve.

Hello dear, J41H-16C is a flanged globe valve, in fact, it is a globe valve with flange connection as the connection method, and its working principle is the working principle of the globe valve - apply torque to the valve stem, so that the valve stem exerts pressure on the valve disc in the shaft direction, so that the sealing surface of the valve disc and the valve seat are tightly fitted, so as to prevent the medium from leaking from the gap.

Advantages: 1. The flanged globe valve is a forced sealing valve, which has good sealing, small friction between sealing surfaces and long service life.

2. The flanged globe valve is composed of several parts: valve body bonnet, valve stem, valve disc, valve stem nut, packing, gasket and hand wheel, which are relatively convenient for manufacturing and maintenance.

3. When the opening height of the valve disc reaches 25%-30% of the nominal diameter, the flow rate reaches the maximum value, indicating that the valve has been in a fully open state, and the disc stroke of the flanged globe valve is small, and its working stroke is also small, and the time required for opening and closing is short.

The globe valve w seal table is a hard seal.

It is called a seal pair where both sides are made of metal or other hard materials"Hard sealed"The sealing performance of this kind of seal is poor, but it is resistant to high temperature, wear and tear, and has good mechanical properties.

When the hard seal gate valve is closed, the sealing surface can only rely on the medium pressure to seal, that is, rely on the medium pressure to press the sealing surface of the ram to the valve seat on the other side to ensure the sealing of the sealing surface, which is self-sealing. Most gate valves are forcibly sealed, that is, when the valve is closed, the ram should be forced to the valve seat by external force to ensure the tightness of the sealing surface.
