I would like to ask the experts: how should high-pressure valves be maintained on a regular basis?
Thread Content
1. Should the stem cover at the top of the valve be oiled and sealed? (Are there any relevant specifications?) 2. There are traces of liquid flow in the small holes on the side of the valve – is it used for drainage? 3. Is it necessary to provide a canopy to cover such valves? Thank you for your advice!
1. Should the stem cover at the top of the valve be oiled and sealed? (Are there any relevant specifications?) Applying oil to the valve stem cover for sealing can effectively prevent dust and rain from entering, ensuring that the valve remains flexible for long periods of time when opened and closed! 2. There are traces of liquid flow in the small holes on the side of the valve; is it used for drainage? This hole is not a drainage hole. This small hole is used to remove the ring that provides retention on the upper part of the valve cover. 3. Is it necessary to provide a canopy to cover such valves? It’s best to install a canopy for shade or set it up indoors!
