Air pilot switch consists of a high-pressure sensor operator connected directly to a three-way air valve that can be operated either normally open or closed. The spring in the sensor applies a counteracting force to the switch and is adjustable within the spring range. All air pilot switches are subject to dead band conditions, which should be considered when using the valve. A dead band is described as the difference in pressure between a set point of sensing pressure and a pressure at which the air valve returns to the original position. Dead band conditions vary by pressure range in percentage with high-pressure conditions reducing the dead band range. Air pilot switch valves are most commonly used to control automatic turn on and shut off of a gas booster or pump system and are used in conjunction with a remote pilot on the booster or pump.

Air Power Hacksaws provide pneumatic power and reciprocating motion to blades. These hacksaw cuts up to 12″ (305 mm) diameter pipe with a single set-up or up to 24″ maximum pipe with optional chain extensions and several clampings.
