Fisher™ 4660 Pneumatic High-Low Pressure Pilot - Emerson
The Fisher 4660 pneumatic high-low pressure pilot activates safety shutdown systems for flowlines, production vessels, and compressors.
Low Pressure Pilot When used within standard safety systems, a pressure sensor monitors a specific media or process pressure source for changes to the norm.
High/Low Assembly - Ruelco
Our standard assembly comes with two pressure switches mounted on a 6″, 1/2″ NPT manifold, tubed together using a 1/4″ stainless steel tubing. The pressure switches can be set to customer-specified settings. The manifold also has a 1/4″ NPT port which can be used as a test connection.
The 4660 high‐low pressure pilot (figure 1) activates emergency shutdown systems for flowlines, production vessels, and compressors. The pilot can be used with either a single or dual set point capability to maintain full output pressure when the process is operating within the set point range.
HLR Controls, original producer of the 7970 Pressure Pilot
The model 7970 pressure switch/stick pilot is our flagship products having sold tens of thousands of units. It is most impressive in its ability to repeatedly retain any setpoint from 10psig to 10,000psig without requiring field personnel to order additional parts and pieces.
HiLo-Matic Pressure Pilot - Plainsman Manufacturing
HiLo-Matic Pressure Pilot is a two position, three-way valve that reliably reacts to pressure input from pipeline. It is used in conjunction with a hydraulic controller and an actuator/valve combination to provide unmanned emergency shutdown of a …
High/Low Pilots | Petro Control
The Petro Controls “R Pilot” is a 3-way, normally closed or normally open, automatic, pressure sensing device. By choosing the appropriate inlet, the sensor can detect pressure above (PSH) or below (PSL) any desired pressure setting.

Model 7970 Pressure (Stick) Pilot based products
The model 7970 pressure sensor is a heavy duty pneumatic or hydraulically controlled switch that can sense pressures ranging from 10 to 10,000 psig - in 1 switch, no extra parts or different springs are needed. This is accomplished by dividing the sensing pressure field into four ranges via a brilliantly designed variable area sensing piston.
