Description Specifications Literature Description The Haskel 28755-3 air pilot switch is a pressure switch that produces a pneumatic signal up to 150 psi at any sensing pressure within its adjustment range of 150-700 psi. It is a 3-way normally closed valve that shifts from its normal position by a rod from the sensing end, which first must overcome an adjustable force spring. The air pilot switch is made of stainless steel and has a PTFE seat seal for positive bubble-tight sealing. It can be used for high-pressure applications up to 60,000 psi and has a high corrosion resistance. The Haskel 28755-3 air pilot switch is ideal for controlling the operation of air driven gas boosters, air amplifiers and liquid pumps.
