Summary. Hello dear<>

<> the material of the J41T-16 globe valve is cast iron, and the J41T-16 globe valve usually uses cast iron material. In general, cast iron is usually used for smaller size globe valves, while cast steel is usually used for larger size globe valves because of the better strength and corrosion resistance of cast steel. However, the specific situation also needs to be selected according to the use requirements.

Is the material of the J41T-16 globe valve cast iron or cast steel?

Hello dear<>

<> J41T-16 shut-off valve is made of cast iron, and J41T-16 shut-off valve is usually made of cast iron. Generally speaking, cast iron is usually used for smaller size globe valves, while cast steel is usually used for larger size globe valves, because of the better strength and corrosion resistance of cast steel. However, the specific situation also needs to be selected according to the use requirements.

Is the J41T upper valve with a thread buckle or with a flange?

The connection method of J41T shut-off valve is usually threaded connection. There are many ways to connect the pipe of the globe valve, but there are two main types: thread connection and flange connection.

On the J41T globe valve, according to the common product specifications and connection methods, it is generally connected by threads. The characteristics of the wire blind carry-on connection are easy connection, good sealing, easy installation, and do not require special tools and techniques.

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.

J41W-16 indicates manual flange globe valve.

The meanings of numbers and letters are as follows:

j stands for globe valve.

4 indicates flange connection.

1 indicates the DC channel, and the disc is unbalanced.

W indicates that the seat sealing surface is directly machined from the body material.

16 indicates that the nominal pressure is 16 kg.

Flanged globe valves are forcibly sealed, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve six from the bottom of the valve disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing material and the thrust generated by the pressure of the medium, and the force of closing the valve is greater than the force of opening the valve, so the diameter of the valve stem should be larger, otherwise the fault of the top bend of the valve stem will occur. In recent years, after the emergence of the self-sealing valve, the medium flow direction of the flange globe valve has been changed from the top of the disc into the valve cavity, at this time, under the action of medium pressure, the force of closing the valve is small, and the force of opening the valve is large, and the diameter of the valve stem can be reduced accordingly.

At the same time, under the action of the medium, this form of valve is also tighter. Our valves"Three chemical give"It has been stipulated that the flow direction of the shut-off valve shall be top-down.

When the globe valve is opened, the opening height of the disc is 25% of the nominal diameter 30%, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the globe valve should be determined by the stroke of the disc. This type of valve should generally be installed horizontally in the pipeline.

J41W-16, manual flange globe valve.

j-globe valve;

4-flange connection;

1-DC channel, disc unbalanced;

The W-seat sealing surface is directly processed by the valve body material;

The nominal pressure is 16 kg.

Flanged globe valve 16 pressure hard sealed.

It should be a stainless steel flange globe valve.

I have production here.

According to the provisions of "JB T 308-2004 Valve Model Preparation Method".

j-globe valve;

4-flange connection;

1== Straight through the runner.

t== Sealing surface material: copper.

16== Pressure Rating:

DN20: nominal diameter.

According to the provisions of "JB T 308-2004 Valve Model Preparation Method": J is the globe valve, 4 is the flange connection, 1 is the straight flow channel, and T is the sealing surface material copper. Specification 16DN20 is the pressure class, and the nominal diameter is DN20.

The general class is based on the globe valve JB T2203 1999 "Globe Valve Structure Length". At present, most domestic globe valve manufacturers are designed and produced according to this standard. However, this standard is not perfect, the specifications are incomplete, the maximum nominal diameter of the single gate globe valve is DN1200, and the maximum nominal diameter of the double gate globe valve is DN1500.

According to the specifications and information of the globe valve produced by the manufacturer, the minimum nominal diameter of the angle globe valve is DN15, and the nominal diameter of the Z-type straight-through globe valve reaches DN2000.
