Selection points

Material: Choose the appropriate material according to the characteristics of the medium in the HVAC system. 304 stainless steel is suitable for general environments, while 316 stainless steel is more suitable for highly corrosive media.

Pressure level: When selecting, make sure that the pressure level of the valve can withstand the maximum pressure in the system.

Valve size: Choose a stop valve of appropriate size according to the diameter of the pipeline to ensure flow control and sealing effect.

FAQ

1.How to install stainless steel globe valves in HVAC systems?

Stainless steel stop valves are generally installed on horizontal pipes to ensure that the flow direction of the medium is consistent with the arrow marked on the valve body, and the valve stem is vertically upward for easy operation and maintenance.

2.How to ensure the sealing performance of stainless steel globe valves?

The sealing surface and valve seat are precisely machined to ensure close contact when closed. At the same time, the corrosion resistance of stainless steel helps to extend the life of the sealing surface and reduce leakage caused by corrosion.

3.How to perform daily maintenance on stainless steel stop valves in HVAC systems?

Regularly check the valve stem, valve disc and sealing surface to ensure that there is no wear or corrosion. Properly lubricate the valve stem to prevent poor operation due to excessive friction.

4.How to extend the service life of stainless steel stop valves?

The service life of ss stop valves can be extended by selecting suitable materials, ensuring correct installation, regular maintenance and use within the design pressure and temperature range.

5.Is the stainless ss globe valve suitable for media containing particles?

It is not recommended to be used for media containing solid particles. The particles may wear the sealing surface and cause the seal to fail. It is recommended to install a filter or use other types of valves before the granular medium.
