NOTICE
Use of water as a primary solvent it is important to control the pH level of the water used. Naturally a pH of (7) neutral
is preferred for optimal performance. If pH becomes acidic, the carbide ball and seat are susceptible to damage and will
cause excessive weeping of fluid. Typically, acidic pH water will leach out the key binders in the carbide ball and seat.
Maintaining good pH balance on waterborne applications is critical for life of the 74160-00 carbide seat and ball. The
DR-1 regulator is designed to handle waterborne paints based on coated stainless-steel construction of the assembly.
Maintaining good pH level of the waterborne materials will assure optimal life.
Product Updates for 2023 - DR-1 Regulator Changes & Improvements
• Release of updated diaphragms (74157-03, 74157-04) used in DR-1 regulator. This change went into effective the 4th
quarter 2023. Test #1 & #2 notes prior vs. new diaphragms.
• Improved sealing power of the carbide ball and seat (74160-00) in the regulator assembly. This change went into
effective the 1st quarter 2024. Test #3 notes prior ball and seat vs. improvements with use of thinner viscosity
fluids.
Replacement Parts Overview
Diaphragms 74157-03 & 74157-04
The DR-1 Regulator is an industrial leader on handling various fluid flows used in a wide variety of viscous fluids. The
regulator is accepted globally as benchmark for controlling fluids for accurate delivery. However, through market shift
supply issues in 2022, it was deemed necessary to source replacement components in the diaphragm assembly both
(74157-03 and -04). The goal was to assure minimal interruption of input pressures to achieve same fluid flows from the
DR-1 regulator. Shown below in various charts are flow rates addressing the many different ratios offered within the DR-1
regulator offerings. These charts outline prior original design diaphragm vs. new design. Test shows we have closely
mimicked the original diaphragm design vs. new design with little performance changes. The goal was to assure minimal
interruption in overall product performance, yet conform to available materials offered within the current marketplace.
Carbide Ball & Seat 74160-00
Focusing on customer requests we are providing product improvements on the DR-1 (74151-XX). We have addressed an
issue on the carbide ball seat to improve performance on thinner viscosity fluids. Complaints were noted that materials
below 10-15 centipoise would allow weeping from the regulator. From product enhancement we have improved the product
to handle 5 centipoise materials to prevent weeping. See page 7 for charts showing leakage of before vs. new at 300
PSI inlet pressure. We have quantified performance based on no leakage within a 2-minute test. The test is using various
viscosity fluids ie...… various solvents, water and both the 40 and 25 second materials tested prior.
