air cylinder is a basic need for many industries

Clean, dry, oil free compressed air and air cylinder is a basic need for many industries.
One drop of unwanted oil can cause an entire automated process to malfunction. It can cause seals in pneumatic valves and cylinders to swell, resulting in sluggish operation - or in worst cases, complete seizure of moving parts.
3 things that can contaminate your compressed air system and ruin your product or processes.
1) Solid particles come from ambient air contaminants like dust and from rusted, oxidized pipework. They will cause pneumatic equipment to malfunction, cause instrument and control failures, and contaminate end products.
2) Condensed water droplets come from the humidity in ambient air. Water will oxidize pipework and pneumatic equipment, ruin paint finishes and end products.
3) Liquid oil and oil vapors are introduced by compressor lubricants and by hydrocarbon vapors present in ambient air. Oil-free compressed air is particularly important in food and pharmaceutical processes.
Compressed Air Filters effectively and efficiently remove solid particles, remnants of oil, water mist and other liquid from compressed air and gas which can…
-wear out pneumatic machinery
-block valves and orifices, causing high maintenance
-corrode piping systems which cause costly air leaks
-result in abrupt equipment stoppages, lost product, time and money
How to clean your Compressed Air…

The Hunter HPV series of Solenoid valve has all the usual features you would expect from a product marketed from Hunter, the self-professed “innovators of irrigation.” First, the valves are made from solid PVC material in construction. What is the significance of PVC? This is ultra-hard material that is also resistant to corrosion and UV-rays. However, this strength is not enough for Hunter. They have also added rigid internal support so as to protect the system from stress failure. After all, you have material flowing at very high-pressure speeds so some reinforcement is to be expected.
The Hunter HPV series of valves was given even more “weight” with a captive diaphragm and solenoid plunger. These features allow for protection against leaks and lifelong capability. Tight bonnet screws ensure that there are no lost parts, whereas internal manual bleed technology keeps the valve box very dry for optimal operation. Though flow control may not be present on some valve products, for the Hunter HPV series of valves maximum flow control is offered to the user, so precise that you can actually control the flow of each system zone.
