H41T Cast Iron Rising Stem Check Valve Introduction 

Cast iron check valves, H41T cast iron lift check valves, and cast iron flange check valves are used on pipelines where the working temperature is ≤ 200℃, to prevent the reverse flow of the medium and serve as one-way shut-off valves. Lift check valves rely on the movement of the medium itself to automatically open and close the valve disc. Lift check valves are a type of automatic valve.Cast iron check valves, H41T cast iron lift check valves, and cast iron flange check valves are used on pipelines where the working temperature is ≤ 200℃, to prevent the reverse flow of the medium and serve as one-way shut-off valves. Their main function is to prevent the reverse flow of the medium, stop the rotation of pumps and electric motors, and regulate the filling of the container. Lift check valves rely on the movement of the medium itself to automatically open and close the valve disc. Check valves can also be used in pipelines that provide supplementary supply to systems where the pressure drop can be reduced to exceed the system pressure. Lift check valves are a type of automatic valve. The main functions of check valves can be divided into swing check valves (based on center adjustment) and lift check valves (moving along the axis). 

 Their main function is to prevent the reverse flow of the medium, stop the rotation of pumps and electric motors, and regulate the filling of the container.Structural features of the H41T cast iron lift check valve: 

The valve disc of the lift check valve is disc-shaped and rotates around the rotating shaft of the valve seat channel. Check valves can also be used in pipelines that provide supplementary supply to systems where the pressure drop can be reduced to exceed the system pressure. Due to the streamlined inner channel, the resistance during movement is smaller than that of the upward butterfly check valve. It is 

suitable for large-diameter places with low flow rate and where the movement does not change frequently, but it is not suitable for pulsating flow. Its sealing performance is inferior to that of the lift type. The main functions of check valves can be divided into swing check valves (based on center adjustment) and lift check valves (moving along the axis). 

 The butterfly check valve is divided into single-leaf type, double-leaf type and half-leaf type.Structural features of the H41T cast iron lift check valve: 

 These three types are mainly classified according to the valve opening diameter, with the aim of avoiding weakening the hydraulic impact when the medium stops moving or flows backward.

 Due to the streamlined inner channel, the resistance during movement is smaller than that of the upward butterfly check valve.1. It is suitable for large-diameter places with low flow rate and where the movement does not change frequently, but it is not suitable for pulsating flow. Its sealing performance is inferior to that of the lift type. Lift check valve: A check valve where the valve disc slides along the vertical centerline of the valve body. The internal thread check valve can only be installed on a horizontal pipeline. The butterfly check valve is divided into single-leaf type, double-leaf type and half-leaf type. On high-pressure small-diameter check valves, the valve disc can be made into a spherical shape. These three types are mainly classified according to the valve opening diameter, with the aim of avoiding weakening the hydraulic impact when the medium stops moving or flows backward. 

Features of H41T Cast Iron Lift Check Valve 

1. The disc-type check valve has the same body shape as the globe valve (and can be used interchangeably with the globe valve), so its fluid resistance coefficient is relatively large. Lift check valve: A check valve where the valve disc slides along the vertical centerline of the valve body. The internal thread check valve can only be installed on a horizontal pipeline. Its structure is similar to that of the globe valve, with the valve body and valve disc being the same as those of the globe valve. On high-pressure small-diameter check valves, the valve disc can be made of a spherical shape. The upper part of the valve disc and the lower part of the valve cover are machined with guide sleeves, and the valve disc guide sleeve can freely rise and fall within the valve seat guide sleeve. The butterfly check valve has the same body shape as the globe valve (and can be used interchangeably with the globe valve), so its fluid resistance coefficient is relatively large. When the medium flows in the opposite direction, the valve disc opens by the medium thrust. Its structure is similar to that of the globe valve, with the valve body and valve disc being the same as those of the globe valve. When the medium stops flowing, the valve disc falls freely to the valve seat, serving to prevent the reverse flow of the medium. The upper part of the valve disc and the lower part of the valve cover are machined with guide sleeves, and the valve disc guide sleeve can freely rise and fall within the valve seat guide sleeve. When the medium flows in the opposite direction, the valve disc opens by the medium's thrust. The straight-through disc-type check valve has the medium inlet and outlet channels perpendicular to the valve seat channel direction; the vertical lift check valve has the medium inlet and outlet channels in the same direction as the valve seat channel direction, and its operating resistance is smaller than that of the straight-through type. 

2. When the medium stops flowing, the valve disc falls freely to the valve seat, serving to prevent the reverse flow of the medium. Lift check valve: A check valve where the valve disc rotates around a pin inside the valve seat. The butterfly check valve has a simple structure and can only be installed on horizontal pipelines. It has good sealing performance. 

3. The straight-through butterfly check valve has the medium inlet and outlet channels perpendicular to the valve seat channel direction; the vertical lift check valve has the medium inlet and outlet channels in the same direction as the valve seat channel direction, and its operating resistance is smaller than that of the straight-through type. 

2. Lift check valve: A valve in which the valve disc slides along the centerline of the valve body. Lift check valve: A check valve where the valve disc rotates around a pin inside the valve seat. The pipe-type check valve is a newly emerged type of valve. The butterfly check valve has a simple structure and can only be installed on horizontal pipelines. It has good sealing performance. 

3. It has a small size, light weight, good processing manufacturability, and is one of the development directions of check valves. Lift check valve: A valve in which the valve disc slides along the centerline of the valve body. However, its fluid resistance coefficient is slightly larger than that of the swing-type check valve. 

 The pipe-type check valve is a newly emerged type of valve.4. It has a small size, light weight, good processing manufacturability, and is one of the development directions of check valves. Compression-type check valve: This type of valve is used as a shut-off valve for boiler feed water and steam. However, its fluid resistance coefficient is slightly larger than that of the swing-type check valve. It combines the functions of a lift check valve and a globe valve or angle valve. 

4. In addition, there are some check valves that are not suitable for pump outlet installations, such as bottom valves, spring-type, Y-type, etc.

Application of H41T Cast Iron Lift-type Check Valve 

1. When the medium flows into the valve body from the direction indicated by the arrow, the pressure of the medium acts on the valve disc, generating an upward thrust. The lift check valve has the advantages of simple structure, reliable operation and convenient maintenance. When the medium thrust is greater than the weight of the valve disc, the valve opens. It is widely used in production processes such as purification equipment, petroleum, chemical industry, metallurgy, power, and textile.

2. When the medium flows into the valve body from the direction indicated by the arrow, the pressure of the medium acts on the valve disc, generating an upward thrust. When the force of the medium pressure behind the valve disc, plus the weight of the valve disc itself, is greater than the force of the medium pressure in front acting on the valve disc, the valve closes to prevent the backflow of the medium. When the medium thrust is greater than the weight of the valve disc, the valve opens. When the force of the medium pressure behind the valve disc, plus the weight of the valve disc itself, is greater than the force of the medium pressure in front acting on the valve disc, the valve closes to prevent the backflow of the medium.
