The PRDHF, non-relieving, single stage pressure regulator is ideal for applications requiring high flow while operating with a steady inlet pressure, up to 500 psig. 

The PRDHF allows for significantly higher flow when compared to the PRD and PRDB series pressure regulators.  The large valve to sensing area ratio and frictionless design, helps to maintain low pressure regulation, such as ½ psi.  The maximum outlet pressure range is (0 -50) psig.  Available with a variety of body (brass, aluminum and 303/316 stainless steel) materials and optional (Viton®, EDPM) seal/diaphragm materials.  Contact our team of application engineers to assist you with your product design.
