The Ruelco pressure switch is the most versatile, robust and easy to adjust pressure switch available. With a maximum overpressure up to 10,000 PSI at any set point or range, the standard Ruelco Pressure switch can be put into almost any pressure environment with 100% function reliability. The easy to change ranges add to the versatility of the product. Unlike our competitors, you will simply change one o-ring if a change of range is needed. This flexibility allows the Ruelco pressure switch to be used in a variety of applications. The combination of our experienced Engineering team and the simple o-ring design also allows the Ruelco switch to be outfitted to meet the customer’s specific fluid or temperature needs. Available in 3 different error ranges and instrument pressures up to 6,000 PSI, the Ruelco pressure switch family can meet any application.

The Ruelco Pressure Switch is used to detect and react to a high or low level signal from a flow source. When the predetermined level has been reached by the sense pressure, the switch will block the inlet instrument signal and bleed the outlet signal. This will cause an instrument pressure drop in the entire system. When a high/ low assembly is used in conjunction with a Ruelco relay, the system can shutdown an actuator or other pneumatically controlled device quickly and safely.

The pilots also have an optional scale which allows the operator to set the switch without the need for trial and error testing. With our all Stainless steel construction, the Ruelco pneumatic or electric pressure switch can meet all of your pressure sensing functions.
