Semi-Precision Dial Knob Regulator - 51R (Miniature, Relieving, Prep-Air II)

Brand: Parker Hannifin

Parker 51R non-modular dial regulators provide a convenient and low cost method to reduce a supplied air pressure to desired outlet pressure. 

They provide quick response and accurate pressure regulation for the most demanding industrial applications. 

This regulator utilizes a pressure indicating dial face that allows full pressure adjustment in 270° turn. 

They are generally used in a wide variety of applications where reduced pressure is highly desirable for energy conservation, safety requirements, air circuit control and air instrumentation. 

51R units are an excellent product for panel mount application. 

For specific flow and space restricted applications, this product can provide a solution that does not sacrifice performance. 

Pressure regulators transform a fluctuating air supply to a relatively constant reduced air pressure within the operating range of the regulator itself.
